In the case of SUV, which are mostly diesel engines, and some diesel cars, sometimes the engine does not start suddenly after parking properly or the engine is turned off while driving.
The injector that injects diesel fuel, which mostly occurs in cars with a mileage of more than 60,000 km, is often a problem.
If the injector needle valve is clogged or the fuel injection is not constant due to a solenoid error, the engine may be embarrassed or the start may be delayed. By making adjustments (injector correction), it is difficult for the driver to easily notice that something is wrong.
Injectors are devices that inject fuel. Like the sprayer that waters plants, the engine's injector is a device that sprays fuel into the combustion chamber like a fog.
A good injector sprays accurately with the correct mist, the correct amount for one spray, and at the correct spray angle without dropping at the end after spraying. Different injectors have different factors that affect performance, and different injectors are cleaned, adjusted, and repaired. Injector cleaning can be regenerated and cleaned only when dedicated and professional equipment is provided.
As a simple injector cleaning method, cleaning is carried out using ultrasonic cleaning protection or pressurized and fuel motor types implemented in real vehicles.
