Description

Definition and application

Injector, a device for injecting liquid fuel into an internal-combustion engine. In diesel engines fuel must be in a highly atomized form for proper combustion. Actually this is accomplished with a plunger and cylinder arrangement, which forces accurately measured amounts of liquid fuel into the combustion chambers through atomizing nozzles. Compressed air is sometimes used in place of a plunger. These injectors are widely used in such diesel equipment as railroad locomotives, trucks, buses, earth movers, ships, and stationary power plants and are sometimes found in aircraft and motor truck spark-ignition engines.

Types of injection

Many diesel engines , however, use direct injection in which the diesel is injected directly into the cylinder filled with compressed air. Others use indirect injection in which the diesel fuel is injected into the specially shaped pre-combustion chamber which has a narrow passage connecting it to the cylinder head . This ensures that the fuel is well mixed with the air before it enters the chamber.Only air is drawn into the cylinder. It is heated so much by compression that atomized fuel injected at the end of the compression stroke self-ignites.

What happens if a diesel injector fails?

Over time, diesel fuel injectors wear out and fail to close completely. When this happens they cause a leak-down, resulting in a reduction of fuel pressure across the fuel rail. This can cause a difficult- or no-start condition as well as a smokey exhaust.

Signs of diesel fuel injector wear:

1. Fluctuating power. If your vehicle is revving inconsistently or your RPM gauge is up and down, this may be a sign your fuel injector needs a clean.

2. Misfiring. Do you find your vehicle misfiring on ignition? ...

3. Fuel odours.

4. Reduced fuel economy.

Maintain

When the injector had used a long time, we need to fix up the injector in time. In order to the excavator can operate normally, avoid faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.

Blockage in the fuel injectors might affect vehicle performance. So periodic fuel injector cleaning might be an ideal choice to boost vehicle performance. It also helps to increase the mileage and keep the vehicle running for long. You need not deal with the terms like lower fuel economy in the future with regular cleaning.
