These valves are mounted on the outlet fittings of the fuel injection pump, one per cylinder injector. They are always mounted at the pump end of the pipes between the pump and injectors. The check valve aspect is a conical valve or 'mitre valve', [i] held against a matching conical seat by a spring. As these valves must work at high pressure ...
Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
A separate cam on the camshaft (as seen in Fig. 5 and on the two-cylinder Johann-Weitzer-engine on the right) would activate the injection valve so the compressed air would then press the fuel into the combustion chamber. Before the injection valve opens, neither fuel nor compressed air can enter the combustion chamber. [16]
The EDS is also intended to automatically trigger the deadman switch, which closes the BOP, kill and choke valves. The EDS may be a subsystem of the BOP stack's control pods or separate. [citation needed] Pumps on the rig normally deliver pressure to the blowout preventer stack through hydraulic lines.
EDC injection inline pump. The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are ...
A Digifant II DF-1 Engine Control Unit used in '91 Volkswagen Golf Cabriolet with 2E engine. Digifant is an Engine Management System operated by an Engine Control Unit that actuates outputs, such as fuel injection and ignition systems, using information derived from sensor inputs, such as engine speed, exhaust oxygen and intake air flow.

An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.
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 ...
