What happens when the fuel leaves the injector?
When the fuel leaves the fuel injector, a spray tip distributes the fuel as a fine mist. Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.”

Why do I have a problem with my fuel injection pump?
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.
How much psi does a fuel injector pump use?
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.
How does a fuel pump and injector affect a diesel engine?
Fuel pump and injector directly affects the performance of a marine diesel engine. The quality of combustion in an engine depends on the working of a fuel injector; which leading to proper automation and optimum injection timing.
How does the plunger affect fuel injection timing?
As the plunger rotates the relative position of helix with respect to the barrel starts to change; altering the amount of fuel to be injected. Additional non return valve discharge valve are fitted in some design to ensure positive seal and avoid corrosion. To affect injection timing we need to change the effective height of the plunger in barrel.
What happens when fuel injector is over cooled?
Over cooling fuel injector negatively affects the viscosity of fuel causing the needle valve to stick and improper combustion in cylinder. Localized over cooling results in high corrosion at the nozzle tip affecting spray pattern. Slack Spring / Weak Spring Tension: A slack spring can cause the effective pressure of ignition to drop drastically.
How does common rail fuel injection system work?
Common rail injection system is a mode of fuel injection in which fuel is injected through a high pressure common rail. This injection method provides a optimized combustion that helps in reducing pollution and overall fuel consumption. Although the system itself is much old but have gain significance in recent times.
