The ignition coil is composed of two sets of coils, the primary coil and the secondary coil. One end of the primary coil is connected to the low-voltage power supply (+) on the vehicle, and the other end is connected to the switch device (breaker).
Spark Plug is a device which is used to ignite the air fuel mixture in the engine cylinder. They are generally used in petrol engine.
LED headlights are used to illuminate the road in front of the car when driving at night, and are symmetrically installed on both sides of the front end of the vehicle.
Automotive sensors convert non-electrical signals into electrical signals and provide the vehicle ECU with information on various operating conditions, including vehicle speed, temperature, and engine operation.
The vehicle engine needs to inhale a lot of air during the working process, and the air contains a lot of dust and particles.
The fuel filter filters the fuel required for the combustion of the engine cylinder, prevents dust, metal powder, water and organic matters from entering the engine, prevents the fuel system from clogging and prevents the engine's precision parts from wear and other damage.
The cabin filter filters the air in the car compartment and the air circulation inside and outside the car, and removes the air dust, impurities, smoke odor, pollen, etc.
The oil filter filters impurities such as metal wear debris, oxidized carbon deposits, colloidal sediments, water, dust and other impurities generated during the working process of the engine, so as to keep the lubricating oil clean and prolong its service life.
It is one of the most important sensors in the engine electronic control system. MAPMS's crankshaft position sensors can improve vehicle engine economy and acceleration performance.
The camshaft position sensor collects the position signal of the valve camshaft and inputs it to the ECU, so that the ECU can identify the compression top dead of cylinder 1, so as to perform sequential fuel injection control, ignition timing control and detonation control.
Oxygen sensor detects the oxygen concentration and air-fuel ratio in the exhaust pipe, controls the automobile exhaust emission, reduces the automobile pollution to the environment, and improves the fuel combustion quality of the automobile engine.
Throttle position sensor, also known as throttle valve opening sensor or throttle valve switch, detects whether the engine is in idle speed condition or load condition, acceleration condition or deceleration condition, is installed on the throttle body.
The mass air flow sensor converts the inhaled air flow into an electrical signal and sends it to the ECU, so that the engine can obtain the best concentration of air- fuel mixture under various operating conditions.
Knock sensor uses the piezoelectric effect to convert the mechanical vibration generated during knocking into a signal voltage.
Vehicle speed sensor is a device used to detect the car's speed and ECU uses this input signal to control the idle speed of the engine, the lock of the torque converter of the automatic transmission, the shifting of the automatic transmission, the opening and closing of the engine cooling fan, and the cruise control.
The manifold absolute pressure sensor detects the change of the absolute pressure in the intake manifold behind the throttle body according to the engine speed and load, and then converts it into a signal voltage and sends it to the ECU, With the signal voltage, ECU will control fuel injection quantity.
The automotive air-conditioning compressor converts the low-temperature, low-pressure gaseous refrigerant from the evaporator into a high-temperature, high-pressure gaseous refrigerant through compression and sends it to the condenser, it is the heart of the automotive air-conditioning refrigeration system.
The high temperature and high pressure refrigerant from the condenser enters into the expansion valve, due to the reduction of the internal section of the expansion valve, the throttling effect is achieved, the refrigerant pressure drops.
When it is raining, the wiper blade wipes out the raindrops on the windshield glass surface, makes driver has clear and wide vision. Driving safety is very important for drivers.
Ultrasonic sensors are installed at the front and rear corners of the car to detect obstacles in all aspects, and use the buzzer and display screen to tell the driver the approximate distance and direction between the obstacle and the car, so that the driver can adjust the orientation in time.
