What is the difference between injection pump and fuel pump?

A fuel pump pressurizes fuel and sends it through the fuel line to the fuel injectors. The fuel injectors atomize the pressurized fuel and inject it into the combustion chamber.

How many types of fuel injection pump are there?

The main types of injection systems include pump-line-nozzle, unit injector, and common rail. Modern injection systems reach very high injection pressures, and utilize sophisticated electronic control methods.

How does a jerk fuel injection pump work?

A presentation explaining the theory and working principle of a Jerk Type Fuel Injection Pump in delivering high pressure metered quantity of fuel to the injector nozzle in an IC engine. The animation and presentation has been made using 3-D CAD modelling in SolidWorks 2012.

What is the definition of a jerk pump?

Definition of jerk pump. : a fuel-injection pump in an oil engine which supplies impulsively an accurately metered charge to the nozzle at the time of the opening of the inlet valve.

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.

What kind of fuel pump does a marine engine use?

There are mainly two types of fuel pump used in marine industry; the jerk type and common rail injection system. A conventional marine diesel engine use a bosh jerk pump to inject fuel into combustion chamber. It contains a single piston structure called plunger which operates; based on the cam profile.

Where is the pump located in an engine?

The pump is usually gear-driven by the crankshaft and is positioned in a central location relative to the engine assembly. Engine and fuel system designers strive to have the pump location such that all of the injection lines are equal in length between the injection pump and the entry to the injectors.
