What is the reason why the injector does not inject fuel?

Insufficient fuel:Under normal circumstances, when the car’s fuel lamp is on, you can still run a distance of 40-50 kilometers, so many friends will not refuel when the fuel lamp is on. The nozzle does not spray oil.

The fuel pump is damaged:As mentioned above, many friends still do not refuel in time when the fuel lamp is on, but you should know that the fuel pump relies on fuel to cool and lubricate, and once the fuel in the fuel tank is severely lacking, the fuel pump is easily damaged.

High pressure oil pump failure:In order to increase the pressure of the fuel injection nozzle and improve the atomization effect of the fuel, the fuel will be re-pressurized by the high-pressure fuel pump and then injected by the fuel injection nozzle. Once the high-pressure fuel pump fails, causing the fuel supply pressure to drop sharply, the fuel injection work of the fuel injector will be affected.

Clogged fuel injector:Because the unsaturated olefins and gums in the fuel will produce a kind of coke-like substance at high temperature, which is what we often call carbon deposits, and when the carbon deposits are heavily accumulated on the fuel injectors, the fuel injectors are extremely There may be clogging, which may affect the fuel injection of the fuel injector.

Can the injector be opened if it is broken?

If the fuel injector is damaged but still able to inject fuel, the vehicle can still be driven. However, a series of problems such as increased fuel consumption, decreased power, and engine jitter will occur during the vehicle's driving.

And if the fuel injector is seriously damaged and can no longer inject fuel normally, or the pressure of fuel injection, atomization effect and other aspects are seriously not up to standard, the engine will not start normally, and the vehicle will not be able to drive normally.
