The fuel injection nozzle is a solenoid valve that injects fuel into the engine cylinder. When the solenoid coil is energized, the suction force is generated. The needle valve is sucked up and the injection hole is opened. The fuel is ejected at high speed through the annular gap between the needle and the injection hole at the head of the needle valve, forming a mist, which is conducive to full combustion.
Oxygen sensor is the key feedback sensor in the control system of EFI engine, which can be divided into two types: zirconia and titanium dioxide.
The oxygen sensor is used to detect the oxygen content in the exhaust gas and obtain the air-fuel ratio signal of the mixture. After the signal is input to the ECM, the ECM adjusts the fuel injection quantity of the engine according to the signal to realize closed-loop control, so that the catalytic converter can play a better role in purification.
Ignition coil is one of the key parts of engine ignition device, which provides sufficient energy for spark plug to generate enough electric spark and improve engine performance.
The ignition coil is mainly composed of primary coil, secondary wire and iron core.
It detects the air intake of the engine. It converts the information of the engine air intake into an electrical signal and sends it to the ECU. It is a sensor to measure the amount of air intake in the automobile intake system. The engine calculates the fuel injection quantity according to the data value of the air intake volume.
Chanto auto parts is committed to the research and development of automobile engine ignition system, specializing in the production and sales of fuel injection nozzle, oxygen sensor, ignition coil, air flow meter, spark plug and other auto parts. The products are mainly exported to South America, North America, Asia, Europe and other regions.
