What is the function of rotary distributor injection pump?
For use on cars and light trucks, the rotary pump or distributor pump was developed. It uses a single injection cylinder driven from an axial cam plate, which injects into the individual fuel lines via a rotary distribution valve.
Does a fuel injection system have a distributor?
Most distributors used on electronically fuel injected engines lack vacuum and centrifugal advance units. On such distributors, the timing advance is controlled electronically by the engine computer. Additionally, eliminating vacuum and centrifugal advance results in a simpler and more reliable distributor.
What is the working principle of a fuel injector pump?
The fuel injection pump is an important part of the diesel engine. The crankshaft gear of the engine drives the camshaft to rotate to complete the fuel injection function.
What are the two types of diesel injection pumps?
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.
What is the difference between inline injection pump and rotary pump?
An inline pump has multiple high-pressure pumps; one for each cylinder. This one has six pumps, one under each outlet port. A distributor pump has ONE high-pressure pump and uses a rotary valve to distribute high-pressure fuel to each cylinder.
What is distributor type fuel injection pump?
A distributor type fuel injection pump is described which consists of: a plunger barrel; a plunger received within the plunger barrel for concurrent reciprocating and rotative motion for suction, pressure delivery and distribution of fuel; a pair of cut-off ports formed in the plunger and the plunger barrel at a …
How does a fuel distributor work?
The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure.
What is jerk type fuel injection 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.

What is a inline pump?
What Is an Inline Pump? Inline pumps (otherwise referred to as straight-line pumps) are a variety of centrifugal pumps whose suction and discharge connections rest in a straight line of piping or are kept with each other inside of the casing. The flow of fluids does not change within an inline pump.
