The role of automotive sensors A sensor is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output in accordance with a certain rule to meet the transmission, processing, storage, display, record, and control. Automotive Sensor Principle The car sensor converts various operating conditions in the car, such as vehicle speed, the temperature of various media, and the operating conditions of the engine, into electrical signals to the computer, so that the engine is in the best working state. There are many automotive sensors. When judging a sensor failure, not only the sensor itself, but the entire circuit where the failure occurs should be considered. Therefore, when looking for faults, in addition to the sensors, check the wiring harness, connectors, and related circuits between the sensors and the electronic control unit. Automotive Sensor Function Introduction [Manifold Absolute Pressure Sensor] Manifold Absolute Pressure Sensor used in electronically controlled fuel injection engine: reflects the change in absolute pressure in the intake manifold, and provides the ECU (engine electronic control unit) with a reference signal for calculating the injection duration; [Air Flow Sensor] Air Flow Sensor: measures the amount of air sucked by the engine and provides it to the ECU as a reference signal for the injection time; [Throttle Position Sensor] Throttle Position Sensor: measures the throttle opening angle and provides it to the ECU as a reference signal for fuel cut, control of fuel-air ratio, and ignition advance angle correction; [Crankshaft Angle Sensor] Crankshaft Angle Sensor: detects crankshaft and engine speed, and provides it to the ECU as a reference signal for determining ignition timing and working sequence; [Oxygen Sensor] Oxygen Sensor: Detects the oxygen concentration in the exhaust and provides it to the ECU as a reference signal to control the fuel / air ratio near the optimal value (theoretical value); [Intake Air Temperature Sensor] Intake Air Temperature Sensor: Detects the temperature of the intake air and provides it to the ECU as a basis for calculating the air density; [Water Temperature Sensor] Water Temperature Sensor: detects the temperature of the coolant and provides engine temperature information to the ECU.

Daimler Stops Developing All-in Electrified Fuel Engines According to foreign media reports, Daimler executives revealed that they will stop future research and development of fuel engines. From now on, the company will focus on the development of electric vehicles. The plan also means that Mercedes-Benz will start to adopt the same strategy. The future will be the era of electric vehicles, and everyone has realized this, and Daimler is no exception. So they decided to develop only electric vehicles in the future. Daimler has previously announced plans to offer electric versions of all Mercedes-Benz and Smart-brand vehicles by 2022. German media reported that Markus Schaefer, head of development at Daimler, said that the company currently has no plans to develop the next-generation internal combustion engine and is focusing on the development of new electric power systems. Although the company is no longer investing in new internal combustion engine engines, Schaefer noted that they will continue to improve certain components to improve the performance of existing engines. Daimler has invested a lot of energy in the development of electric vehicles in recent times. With a large commercial vehicle product line, Daimler has now launched a wide range of electric models, from vans to small trucks, and even large trucks and buses. The first electric model launched by Mercedes-Benz is the EQC electric SUV, and EQB and EQS models will be introduced in the future. In addition, Smart has also become a pure electric vehicle brand. In addition, the development time of recent generations of internal combustion engines has become longer than before, and other factors may also reduce their investment value. For example, some countries have already implemented a ban on gasoline vehicles, and some have announced that they will ban the sale of new gasoline and diesel-powered vehicles by 2040. This has also led auto companies such as Volkswagen and Daimler to rethink their long-term strategies for powertrains.

Volkswagen Sued in Canada for Alleged Violation of Environmental Protection Law According to foreign media reports, on December 9, a Canadian government agency said that German carmaker Volkswagen was sued in Canada because the company imported nearly 128,000 cars into Canada that violated the country's environmental laws. The Canadian Department of Environment and Climate Change (ECCC) said that Volkswagen has violated the country's environmental protection legislation by importing vehicles that do not meet emissions standards into Canada, so the company faces 60 charges, including two "misleading Information "allegations. The Ontario court will hold a hearing on December 13. A Volkswagen spokesman said the company would fully cooperate with the ECCC investigation. "At the hearing, the parties will submit a proposed guilty resolution for consideration and seek court approval," he said. In 2015, the agency also launched an investigation into a number of Volkswagen vehicles, as they were allegedly equipped with "reduction devices" prohibited by law. The agency said that in this incident, the efficiency reduction device was software that reduced the effectiveness of the emission control system during normal vehicle use. Sources in 2015 said that Volkswagen used the device in vehicles to cheat in emissions tests. The move has caused Volkswagen to lose € 30 billion (about $ 33 billion), including fines, vehicle modifications and legal costs, and the incident has also led to resistance to diesel vehicles worldwide.

In recent years, the United Kingdom, France, the Netherlands, and India have announced timetables for discontinuing the sale of fuel vehicles. China has also started to formulate this plan. Therefore, it is a general trend for new energy vehicles to replace fuel vehicles as the main model. The increasing proportion of new energy vehicles in overall new car sales also means that the proportion of new energy vehicles in the used car market will also increase, but this is the biggest crisis in the used car industry. According to the data in the "2019 China Car Hedge Rate Report" issued by the China Automobile Finance and Hedging Rate Research Committee, the three-year average value preservation rate of mainstream new energy vehicles in China is only 32.31%, while similar fuel vehicles are generally about 60%. Some car dealers said that if new energy vehicles are rushed back, it is likely that they will not be sold for months or even half a year, and during this period, the risk of discounting the vehicles is also high. In other words, if the problem of battery consumption of new energy vehicles is not solved in one day, it will be difficult to increase the value preservation ratio in the used car market. Once the proportion of new energy vehicles in car sales increases in the future, the used car market must If new energy vehicles are not accepted, then these used new energy vehicles will not be sold for a long time, which will directly bring down the entire used vehicle industry. Data from a used car management system show that used car dealers in China sell about used cars with an average price of about 150,000, with an average gross profit margin of about 5%, which has continued to decline in the past two years. The average gross profit margin was only 4.6%. In the future, if new energy vehicles continue to be sold at such a low value preservation ratio in the used car market, excessive turnaround time will greatly increase the cost of the industry, and the average gross profit margin of used cars will be further reduced. Therefore, there are already car companies exploring the residual value management model of new energy vehicles. For example, Weimar has established a used car detection system, a used car e-commerce platform system, a used car official certification system and a used car quality assurance system. Xiaopeng Automobile provides a new version of the 2019 G3 owners with a 40% discount to repurchase Xiaopeng Automobile's equity after 3 years. However, these measures are doomed to the symptoms and not the root cause, and the source is still the battery. Traditional fuel vehicles have been stable for 5-7 years in various aspects and do not require overhaul. According to current battery technology, it takes about 3-5 years to replace the batteries. What's more, the current replacement of new energy vehicles is more frequent. The longer they are used, the lower the value in the used car market and the lower the possibility of their being sold. As the current second-hand car practitioners worry, "If you rush to take back new energy vehicles, you will probably hit your hands."

The head of Renault may change again. According to French media reports, the current head of Alstom (Alstom, a global leader in transportation and power infrastructure), Henri Poupart-Lafarge, may become Renault's new CEO. Henri Poupart-Lafarge In fact, the scramble over CEO position of Renault has been going on for a month. Earlier this October, Renault chairman Jean Dominique Senard expressed dissatisfaction with Thierry Bollore (then CEO of Renault). Bolloré was subsequently terminated as CEO by Renault's board, and Clotilde Delbos, then Renault's chief financial officer and senior vice president, served as interim CEO. In November of this year, Renault's board of directors stated once again that they were still dissatisfied with Delbos' work and that Renault's work of selecting a formal CEO continued. At this time, including Luca de Meo, global president of the Seat brand of Volkswagen Group, Didier Leroy, executive vice president of Toyota, and CEO of Faurecia, a component company Candidate lists such as Patrick Koller were revealed. Renault Group Today, Renault CEO candidates have changed again. If nothing else, Renault will announce the official CEO candidate during the next board meeting. In accordance with foreign media analysis, although the position of Renault CEO in the automotive industry is not attractive, Lafarge may be interested in this position, but his weakness is also very obvious, that is, he has never worked in the automotive industry. . According to Renault's previously released financial data for the third quarter of 2019, its third-quarter revenue was 11.296 billion Euros, down 1.6% year-on-year; and global sales were 852,000, down 4.4% year-on-year. The performance of Renault in the Chinese market is not optimistic. According to relevant statistics, up to October this year, the cumulative sales of Dongfeng Renault was 12,811 units, a year-on-year decline of 73%.

Cummins founded in February 1919 and headquartered in Columbus, Indiana, Cummins provides services to customers through its more than 500 distribution facilities and more than 5,200 dealer locations in more than 190 countries. Cummins is a Fortune 500 company in US and has been elected [Fortune", [the World`s Most Respected Company" for two consecutive years in 2008 and 2009. It is only diesel engine company on the list. In addition, Cummins has been selected for the fourth consecutive year in the Dow Jones Global Sustainability Index for its outstanding performance in economic development, environmental protection and social responsibility. Among the world's 2,500 companies, only the top 10% of the key sustainability indicators can be selected for this list. The historical origins of Cummins and China can be traced back to the 1940s more than half a century ago. On March 11, 1941, US President Franklin Roosevelt signed the Renting Act to provide wartime assistance to 38 countries including China. The "Lending Law" includes Chinese military patrol boats and military trucks equipped with Cummins engines. At the end of 1944, a Chongqing company sent a letter to Cummins Inc. that seeking to establish commercial links, and localized production of Cummins engines in China. At the time, Cummins Engine General Manager Elvin Miller expressed strong interest in the reply and hope that Cummins can build a factory in China after the end of the Sino-Japanese War. For reasons that are well known, Mr. Miller`s ideas can only be reached in the 1970s, 30 years later, with the gradual easing of Sino-US relations. Cummins invested more than US$240 million in China. As the largest foreign investor in China's diesel industry, Cummins' business relationship with China began in 1975. At the time, Mr. Elvin Miller, Chairman of Cummins, visited Beijing for the first time and became one of the first American entrepreneurs to seek business cooperation in China. In 1979, China and the United States established diplomatic relations. At the beginning of China's opening to the outside world, the first Cummins office in China was established in Beijing. Cummins has long adhered to a strategic alliance with large Chinese companies to achieve common development. As the first foreign-funded diesel engine company to come to China for localized production, Cummins has established four engine joint ventures with leading Chinese commercial vehicles including Dongfeng Motor, Shaanxi Automobile Group and Beiqi Foton for more than 20 years. Cummins 18 Eleven of the engine series have been produced locally in China. After more than 30 years of development, Cummins has become an integral part of the Chinese engine industry. Through joint venture/sole proprietorship production and technology transfer, it has made its own contribution to the modernization of China's engine industry.

It remained within a reasonable range, showing a good pattern of steady growth, good employment, stable price and supply quality and efficiency improvement. In the economic growth rate, GDP in the first half of 2017 increased by 6.9% year-on-year and about 0.2 percentage points higher than the same period of last year. This is also the highest in the fourth quarter of 15 years. Up to the second quarter of this year, the growth rate of GDP has stabilized in a medium-to-high speed range between 6.7%~6.9% for eight consecutive quarters, indicating that China`s economic fluctuations have already stabilized. In 2017, there have been new changes in the domestic auto market and aftermarket. The total amount of automotive is still at a high level, and the impact of the aftermarket is more growing. According to the statistics of the Automobile Industry Association, the sales of cars in the country have exceeded 28 million. The Traffic Management Bureau showed that the number of motor vehicles exceeded 300 million for the first time, and the number of vehicles reached 200million. The transportation department expects that the average annual growth rate of auto aftermarket in China will exceed 30% in the future. After 2018, the market scale is expected to break by one trillion Yuan and will reach 214 billion US dollars by 2020. The auto aftermarket remains robust in this first half of year, with a nearly 20% year-on-year increase. In addition, the average age of automobile in China will expect to exceed 5 years in 2018. In accordance with the development history of developed countries, once the vehicle age is more than 5 years, the auto aftermarket will usher in new prosperity! China`s new car market has reached the top of the world for 7 years and its vehicle ownership more than 200 million. Under this background, auto industry has entered into stock market, and aftermarket will fully go into the era of brand-developing. The national consumption upgrade is accelerating and the potential of vehicle personalization is huge in the market!

According to Agence France-Presse reported on June 29, the automotive industry analyst said on the 28th: although the US new car sales down since 2016, the market stable demand on second-hand car means that the US auto dealers will remain strong sales this year. Cox Motor CEO Jonathan Smok said the data has shown that the focus of the car sales market is gradually turning to second-hand car transactions. "Dealers are now selling more cars, but selling more of them are second-hand cars." "The market changes are driven by buyers under the age of 40, those buyers bought 29% of US cars , and they are more likely to buy a used car. Whether the price of the car can be afford is an important consideration for the millennium buyers." Said Rebecca Lindland, an executive analyst at Kelley Blue Book, a US professional car value assessment network. Cox Motor International industry insight senior director Charles Chesbrough said the new car sales maintained a relatively strong level, but has been from 2016 peak 17.5 million continue to decline. "It is hard to say that this industry is on the brink of collapse unless there is a economic recession or a financial event." In recent years, the strong sales of new cars in the United States (including cars, trucks, especially sport-type utility SUVs, which are popular with American drivers and often discounted sales) mean that their competitors - The second-hand car's supplier increased. Dealers are also willing to spend more money to buy second-hand cars, to ensure that there are enough second-hand car inventory. In addition, a significant number of rental cars are returning to the market with low mileage, relatively new second-hand vehicles. According to data provided by Cox International, 3.6 million rental cars will return to the market in 2017, compared with 3 million in 2016. By the end of 2020, there will be 4.6 million leasing vehicles returning to the market each year. These rental cars are rapidly becoming an alternative to new cars, In the future, there will be more rental vehicles returning to the market. "Overall, Although the new car sales slowdown, we still believe that the current car market is healthy, and about 17.1 million car sales will make 2017 the best year for car sales in industry records," Smok said.

Did you meet the Cummins engine start difficult, but do not know where to start? Look at the 8 different cases to help you learn more: Case 1 Starter and engine are normal start speed, but not ignition; or sometimes before it's final starts, must experience many and long-time starting: Cause: The fuel line has air. Fault nature: mechanical failure. Fault analysis: For ISL & ISZ engines, automatic exhausting can be performed with an electronic pump. Connected to power, electronic pump automatically work for 30 seconds. Disconnect if the switch is switched on. Repeat this step to allow engine exhaust. For the ISB & ISD engine, there is no electronic fuel pump, the oil row of air is relatively difficult, often the operator felt the air to exclude clean, the actual or not completely clean. According to the actual use of the situation, you should release the oil pump back to the oil bolt to drain the air, if necessary, can release the high-pressure tubing, the use of starter to drive the engine idling to air; if only the release of the fuel filter bleed screw Exhaust air, may not be easy to completely eliminate the fuel pipeline air, more laborious. Treatment method: exhaust the fuel pipeline air. Case 2 Both the starter and the engine have a normal starting speed, but no ignition. Cause: The ECU has a fault code. Fault nature: electrical failure. Fault analysis: The vehicle are normal by checked from the mechanical aspects, diagnosed with a diagnostic device found "water temperature sensor", "rail pressure sensor", "accelerator pedal" and some fault display, clear the fault code, the engine started smoothly. This situation is maybe the maintenance or operation of the electrical control system connector plug-in operation, so the system will generate a fault code stored in the ECU, the system will protect the role of some functions can not even start. Treatment method: Clear the fault code. Case 3 Both the starter and the engine have a normal starting speed, but no ignition. Cause: The engine harness is damaged or the connector is defective. Fault nature: electrical failure. fault analysis: the probability of damage to the engine harness is small, big probability is connector defective. Do not replace the engine harness easily before eliminate the connector defective reason. At this point, you can use the diagnostic device to diagnose the approximate area of ??the occurrence of the failure, and then excluded. Treatment Method: Replace the engine harness or re-plug the connector (Note: must turn off the power first). Case 4 Both the starter and the engine have a normal starting speed, but no ignition. Cause of failure: The pump is not installed correctly or the flywheel does not match. Fault nature: mechanical failure. Fault analysis: This situation usually occurs in the engine that has been replaced with the oil pump or flywheel. For oil pump installation engine, the oil pump must be installed correctly. In addition, if the flywheel is replaced, it must use the original flywheel that have the sensor holes. Treatment Method: reinstall the pump or use the matched flywheel. Case 5 Both the starter and the engine have a normal starting speed, but no ignition. Cause: Crankshaft speed sensor and camshaft position sensor are faulty. Fault nature: electrical failure. Failure analysis: This situation is generally not much. Use the diagnostic instrument to detect the crankshaft speed sensor and camshaft position sensor at the same time, it will show the fault display. Treatment Method: Replacement. Case 6 Both the starter and the engine have a normal starting speed, but no ignition. Cause of failure: High pressure common rail failure. Fault nature: electrical failure. Fault analysis: This fault is sometimes a rail pressure sensor failure, sometimes the oil rail pressure control valve failure, if the rail pressure control valve in the open state, the rail pressure can not be established, thus can not start. Treatment Method: Replacement. Case 7 The starter has no speed. Cause of failure: No power supply, insufficient voltage or starter failure. Fault nature: electrical failure. Fault analysis: the starter electric current is too large or the ring gear can not be engaged with the flywheel; the voltage is insufficient and the engine can not reach the starting speed. Treatment Method: Turn on the power or replace the starter or charge the battery. Case 8 Both the starter and the engine have a normal starting speed, but no ignition. Cause: The neutral position switch or clutch switch is faulty. Fault nature: electrical failure. Failure analysis: This fault should belong to vehicle failure. Treatment: Replacement

Head Gasket is also named as: cylinder head gasket, cylinder gasket, CYL gasket, CYL Head Gasket, Head gasket- It`s a sealing gasket that sits between the engine block and cylinder head in an internal combustion engine, typically thickness range from 1.2mm-2.0mm. The purpose of the head gasket is to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders; it is the most critical sealing application in any engines. As part of the combustion chamber, it shares the same strength requirements as other combustion chamber components HEAD GASKET MATERIAL TYPES: Traditional composite material Head Gasket---This is an old technology, Its made from asbestos or graphite or non asbestos (Free asbestos or asbestos free).Fiber composite metal sheet body with armor together. Asbestos gaskets qty is falling because environment conservation and human health concerns. But still have a large inventory in the market. Solid copper material Head Gasket– a solid copper sheet, usually requires special 'o-ringing' that places a piece of wire around the circumference of the cylinder to bite into the copper. This O-Ringing can make the cooper gaskets durable; recently companies have started producing copper gaskets with integral sealing wires permitting their retrofit into engines without the removal of the engine block for machine work. Metal or MLS or Multiple Layers Steel Head Gasket– Modern head engines are produced with metal or MLS gaskets. These typically consist of three layers of steel, four or 5 layers are also available. The contact faces are usually coated with a rubber-like coating such as Viton or FKM that adheres to the cylinder block and cylinder head while the thicker center layer is left bare.
