How does the fuel pump and injector work?
The injection pressure of fuel to be injected into cylinder is controlled by the fuel injector; and the amount and timing of such injection is controlled by the fuel pump. This injection pressure of a fuel injector depends upon its spring setting set by the manufacturer. On another hand a fuel pump works based on the position of cam and camshaft.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.

Can a diesel fuel pump injector be clogged?
Diesel fuel pump injectors are high-precision components. They also deal with a tremendous amount of motion and other stresses. One small visitor inside (a piece of dust, debris, etc.) can clog the injector. Worse yet, a microscopic object can leave the injector open all the time. If the injector can’t close, cylinder performance is compromised.

What happens if the fuel injector is not working?
Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.
How can I keep my fuel injector in good health?
Another great way to keep injectors in good health is; to regularly add a fuel injector cleaner to to your fuel tank. Many manufacturers claim that these cleaners, will give your car extra power or increased mpg. They probably won’t, or make much difference, to a car that is running properly.
What should I do if my fuel injection pump is stuck?
If it is stuck then don’t tap or hit it as it will damage it. You would need to take it to a diesel engineers to have the seized element replaced if you have no luck. With the TEF fuel injection pump you can also remove the cover plate to look inside at the components. Share This Story, Choose Your Platform! Comments are closed.
What are the different types of fuel injection pumps?
There are two types of injection pumps on conventional diesel engines, inline pump and distributor pump. We have discussed the difference between the two types of pumps in the previous article, you can access these 3 types of fuel injection pump in diesel engines.
When does the fuel injector open and shut off?
The fuel pump will come on when the fuel pressure within the fuel lines drops to a certain level. Once that level is reached, the fuel pump shuts off. The cycle between on and off time for a fuel pump is measured in seconds. A fuel injector will open when It receives a pulse generated by the car’s computer.
How does an inline injection pump work in a diesel engine?
Inline injection pump is a high pressure pump on a diesel engine that is used to increase diesel fuel pressure up to 18,000 PSI individually. That is, each injector will be served by a plunger unit. It can be said, in a 4 cylinder diesel engine there are 4 injectors and 4 plungers.
What are two types of fuel injection pumps?
Maybe you only know there are only two types of injection pumps in diesel engines. But if we see further, there is one type that is actually applied to many recent vehicles. 1. Individual inline pump An individual pump is a pump mechanism with an individual fuel delivery system. That means that each injector will be served by a plunger mechanism.
How does the fuel pump injector pump work?
The fuel pump or lift pump just delivers fuel from the fuel tank to the inj pump. The inj pump does all the really hard work of delivering the fuel to the cylinders via the injectors. To test the lift pump, once the engine is running, open the bleeder at the fuel filter.
What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
Where is the fuel pump on a diesel engine?
The common rail distributes the fuel to the injectors, which are mounted on each cylinder of the engine. Distributor (rotary) fuel injection pump. This diesel fuel pump is also controlled electronically by various sensors, an electronic control unit, and an actuator.
What should I replace my diesel fuel pump with?
Genuine GM Parts™ Fuel Water Separator Filter by ACDelco®. Bring your vehicle’s fuel system back to its top shape with this top-notch part. Designed as a direct-fit replacement of your worn-out or malfunctioning part, it will… Diesel Fuel Transfer Pump by Standard®.
What causes a fuel injector to stop delivering fuel?
An injector becomes clogged with fuel varnish deposits and fails to deliver its normal dose of fuel when it’s energized, or. Fuel pressure to the injector drops below specifications because of a weak fuel pump, plugged fuel filter or leaky fuel pressure regulator.
What kind of pump does a diesel engine use?
Mechanical systems are camshaft operated, while hydraulic systems use engine oil supplied by a high-pressure pump. All systems have a low-pressure pump that transfers fuel from the tank to the injection pump or unit injectors. The fuel is filtered along the way but the filters on diesel engine vehicles commonly incorporate a water separator.
