How the oil injector works
An oil injector is a device used to supply fuel to an engine. It works as follows:
1. Air intake: the oil injector is sucked into the air layer from the air filter of the car engine through the intake port.
2. Mixing: The air enters the gas pipe of the oil injector through the throttle valve and meets the throttle under the oil injection valve. During this process, the engine control unit (ECU) measures the intake volume through sensors and determines the appropriate fuel mix ratio.
3. Oil injection: The ECU opens the oil injection valve at the appropriate time according to the needs of the vehicle. The injection valve allows fuel to flow from the fuel supply system into the injector and then out through the tiny injection nozzles. These tiny nozzles spray fuel precisely into the air stream in the trachea, creating a combustible fuel-air mixture.
4. Mixed combustion: After injection, the fuel is mixed with air to form a combustible mixture and then sucked into the cylinder by the air rushed by the intake. Inside the cylinder, the mixture is ignited by the ignition system, creating an explosion that drives piston motion.
This is the working principle of the fuel injector, by controlling the injection and mixing of fuel, it can ensure the normal operation of the engine under different conditions, and achieve the effective combustion of fuel.
