Specification

Description

Individual Pump and Nozzle System{In this system,each cylinder is provided with one pump and one injector.

The pump may be placed close to the cylinder or they be arranged in cluster

The high pressure pump plunger is actuated by a cam, and produces the fuel pressure necessary to open the injector valve at the correct time.

4 Common Diesel Fuel Injection Pump Problems

Fuel injection pump performance is closely tied to engine performance. If your vehicle has a fuel delivery issue, it will literally starve to death. Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.

Diesel Fuel Injection Pumps – Quick Overview

So what does a diesel fuel injection pump do? It’s about as simple as you can get: fuel injectors supply fuel to the engine’s internal combustion chamber. High-performance automobiles usually have one fuel injector per cylinder, and the pump “injects” fuel into the combustion chamber – hence the name “fuel injector.”

The fuel is dispersed from the injection pump to the combustion chamber via a fairly simple process. Pressurized fuel enters the fuel injector. Based on a signal from an electrically controlled solenoid valve – the solenoid valve acts as a type of on / off valve – the fuel enters a plunger, which prepares the fuel for the final exit. When the fuel leaves the fuel injector, a spray tip distributes the fuel as a fine mist.

A Two-Headed Monster – A Pair of Reasons that Explain Fuel Injector Pump Failure

99% of diesel fuel injector failure can be traced to two different issues:

• Faulty mechanical problems in the physical fuel injector housing

• Fuel quality (or rather, lack of quality)

From these two things, a host of problems can surface. Let’s take a look at 4 common fuel injector pump complications.
