Fuel injected engines use either electric fuel pumps mounted inside the fuel tank (for lower pressure manifold injection systems) [1] or high-pressure mechanical pumps mounted on the engine (for high-pressure direct injection systems). Some engines do not use any fuel pump at all. A low-pressure fuel supply used by a carbureted engine can be ...

The pump plunger begins descending, but the spill valve is open, and fuel recirculates back to the return line. Injection phase Partway through the pump stroke, the solenoid is energized, which closes the spill valve. The fuel is forced into the cylinder through the spray tip. Pressure reduction phase Toward the end of the pump stroke, the ...
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
fully demand-controlled and returnless; – fuel tank–mounted low-pressure fuel pump; Fuel Stratified Injection (FSI): camshaft-driven single-piston high-pressure injection pump supplying up to 150 bar (2,180 psi) fuel pressure in common rail fuel rail integrated into the inlet manifold, four combustion chamber sited direct injection ...
The basic operation can be described as a sequence of four separate phases: the filling phase, the spill phase, the injection phase, and the pressure reduction phase. A low-pressure fuel delivery pump supplies filtered diesel fuel into the cylinder head fuel ducts, and into each injector fuel port of constant stroke pump plunger injector, which ...
fuel system & engine management low-pressure fuel tank mounted fuel lift pump with underfloor electric fuel relay pump, timing belt-driven high-pressure injection pump delivering up to 1,850 bar (26,830 psi) pressure for the common rail (CR) fuel rail, direct injection (DI) with eight-nozzle output piezo fuel injectors; Bosch EDC 17 electronic ...
Furthermore, vane pumps can be used in low-pressure gas applications such as secondary air injection for auto exhaust emission control, or in low-pressure chemical vapor deposition systems [citation needed]. Rotary-vane pumps are also a common type of vacuum pump, with two-stage pumps able to reach pressures well below 10 −6 bar.
