Crankshaft sensors are used in various fields, but with the development of technology, more are used in cars. The crankshaft sensors of each car are usually made by OEMs, and the price is also uneven. Today, Xiaobian has compiled a list of companies in the crankshaft sensors of several cars, as well as the market price of crankshaft sensors of various companies. The following are only personal opinions, but I still hope to help the readers.
Crankshaft sensor manufacturerCrankshaft sensors are now used in many applications, not only in automobiles, but also in many areas. There are also many crankshaft sensor manufacturers on the market, with different performances of different types of crankshaft sensors. The ignition time of the crankshaft sensor engine (simplified, that is, the moment the spark plug is fired, the corresponding crankshaft position) is very accurate (correctly speaking, there is a range in which the crankshaft is turned to this angle) The fire plug is required to ignite, the crankshaft has not been turned to this position, the spark plug is ignited, and the engine is impossible to work normally. The former carburetor car uses a mechanical electric switch to control the ignition of the spark plug as long as the crankshaft Turning to the switch position, the spark plug will ignite. Now that it is all electronically controlled, then the computer needs to know what angle (position) the crankshaft is going to, and can only find a way to make an electrical signal, let the computer know what angle the crankshaft is going to, and once it has turned to the best ignition position, The computer controls the ignition. The crankshaft position only has strict requirements on the ignition timing, and the injection is relatively minor, because the injection is slower and slower, and the impact on the operation fee is not too great, but if the ignition is not normal, the impact is very large. . Common crankshaft sensors are electromagnetic (there is a square gear on the crankshaft. Mounted against the gear). The simplified physical model is a small permanent magnet generator. The most common one is this one. Others There is a photoelectric type (a small disc with a lot of small holes on the upper and lower sides of the disc, correspondingly installed point device and photosensitive device, light-emitting element, emitted light, when the disc is turned to the hole position, The light shines on the light-receiving element that receives the light below.) The simplification model is actually a photocell, and the other is a Hall sensor. More than 95% of the cars on the road are the first one.
There are many types of crankshaft sensors, imported and domestic. The following is a small series of manufacturers of crankshaft sensors for everyone to refer to.
Delphi (DeLphi) company introduction:
Founded in 1890 and headquartered in Warren, Ohio, USA, Delphi is the world's largest manufacturer of automotive wiring harness systems. It supplies almost all major domestic vehicle manufacturers, including FAW-Volkswagen, General Motors, and Shanghai Volkswagen. , Dongfeng Nissan, Chery and so on.

Introduction to Siemens VDO:
This brand believes that everyone is not strange, Siemens is not only famous for making home appliances, Siemens VDO Automotive Technology Wuhu Co., Ltd. was established on May 10, 1995, by SIEMENSVDO, a subsidiary of the German multinational company SIEMENS, and the construction company of Wuhu Economic and Technological Development Zone. A joint venture company, the company is located in the beautiful river city of the Yangtze River - Wuhu. Siemens VDO Automotive Technology Wuhu Co., Ltd.'s products are mainly automotive electrical products: automotive instrumentation, sensors, fuel pump, central locking, throttle body, cruise system, idle speed stability valve.
Siemens VDO crankshaft sensor model introduction:
The price range is from tens of yuan to two or three hundred yuan.
Different crankshaft sensors have different price points according to individual needs. We simply query the prices of relevant common trading platforms for reference.
Advantages of Delphi Crankshaft Sensors:
As a partner of 25 of the world's largest automakers, Delphi is committed to providing customers with parts that are fully compliant with the original quality standards. After more than a hundred years of development history, innovation. High standards and deeper essence, the essence of the formal appearance creates a truly unique original accessory product.
Advantages of Honeywell crankshaft sensors:
Sensors that are fast and long-lived are basically compatible with other electronic circuits and produce proportional outputs that respond to the presence or interruption of the magnetic field.
Advantages of Bosch crankshaft sensors:
There are many types, genuine, quality assurance, anti-counterfeiting Peugeot. The air flow meter is a very important start signal. The air flow meter can accurately transmit the air intake amount, intake density, intake air temperature and other signals to the ECU (automobile computer). The vehicle ECU gives a match through the transmitted signal. The most appropriate gasoline (sprayed through the injector) gives the best possible air/fuel ratio.
Advantages of the Siemens VDO crankshaft sensor:
For the development partners of various automakers, the product line covers drive systems, engine management electronics and fuel injection systems, and strives to improve overall engine performance and reduce emissions.
