when the car fuel injector is broken what will happen?

What symptoms will appear when the car fuel injector is broken?

Engine shaking, power reduction, increased fuel consumption, increased exhaust emission pollution, difficulty in starting, engine cylinder missing, black smoke from car exhaust, unstable idling.

Broken fuel injector will cause a series of problems that affect the normal operation of the engine. The following are some points that may occur after the fuel injector is damaged:

Engine shaking: Broken fuel injector will affect the normal injection of fuel, causing the engine to run unsteadily and shaking.

Power reduction and increased fuel consumption: Broken fuel injector will affect the injection volume and injection pressure, resulting in a decrease in vehicle power and increased fuel consumption.

Increased exhaust air pollution: Fuel injector failure will affect the mixing gas burning and combination, resulting in an increase in pollutants in exhaust emissions, and in severe cases, black smoke from exhaust.

Difficulty in starting: When the fuel injector is severely damaged, it may cause difficulty in starting the vehicle, or even suddenly flame out during driving.

Engine cylinder missing: Severe damage to the fuel injector of individual cylinders may cause the engine cylinder missing, causing the engine to shake violently.

Black smoke from vehicle exhaust: When the fuel injector is damaged, the fuel is poorly atomized and not fully mixed with the air, resulting in incomplete combustion, which causes black smoke in the exhaust gas.

Unstable idling speed: Broken fuel injectors may cause unstable engine speed at idle speed, resulting in unstable idling speed.

Fault light on: The vehicle's fault diagnosis system may detect a fuel injector failure and light up the fault light on the dashboard.

Although the fuel injector is a simple solenoid valve, it is crucial to the performance of the engine. When the fuel injector fails, it should be repaired or replaced in time to ensure the normal operation of the engine.
