How does injection pump work on a diesel?
An Injection Pump is the device that pumps fuel into the cylinders of a diesel engine. It rotates at half crankshaft speed in a conventional four-stroke diesel engine. Its timing is such that the fuel is injected only very slightly before top dead centre of that cylinder’s compression stroke.
Which part in the fuel injection pump compress the diesel?
Pump elements such as the cylinder and plunger are built into the injection pump body. The fuel is compressed to high pressure when the cam lifts the plunger, and is then sent to the injector.
What are the parts of injection pump?
- Overview.
- High Pressure Pump.
- Accumulator.
- Fuel Injector and Fuel Injection Nozzle.
- Fuel Metering.
- Nozzle Needle Control Actuators.
Which is the correct order in which fuel is injected?
Explanation: The fuel flows from the fuel tank to the feed pump where the pressure is increased and then the fuel is filtered by the filter and then it is sent to the injector. Therefore the correct sequence of the fuel flow is fuel tank – feed pump – filer – injector. 10.
What are injector nozzles?
Injector nozzles interact with Pistons in Combustion Chambers. When the Piston is drawn away from the Sparkplug, the Injector Nozzle sprays a fuel and air mixture into the Combustion Chamber. Injector Nozzles can be thought of as the “heart” of the engine.
What does a fuel injection pump do in a diesel engine?
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.”

What’s the PSI of a diesel fuel injector?
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. Fast-forward to the present day, and those diesel fuel injector pumps are operating in the 30,000 to 40,000 psi range.
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.
