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.
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 ...
K-Jetronic was a mechanical injection system, using a plunger actuated by the intake manifold pressure which then controlled the fuel flow to the injectors. [ 52 ] Also in 1974, Bosch introduced the L-Jetronic system, a pulsed flow system which used an air flow meter to calculate the amount of fuel required.
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 ...
Electrolysis is possible with both traditional fossil fuel energy sources, as well as low-carbon electricity sources such as wind, solar and nuclear power. [ 2 ] : 7 [ 3 ] The process uses carbon dioxide in manufacturing and releases around the same amount of carbon dioxide into the air when the fuel is burned, for an overall low carbon footprint.
In some cases the engine's fuel pump is integrated in to the fuel control. Electronic engine control (EEC): An EEC is essentially a hydromechanical fuel control but with added electrical components to prevent overheating or overspeeding the engine.
The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...
A modern gasoline pump is divided into two main parts – an electronic "head" containing an embedded computer to control the action of the pump, drive the pump's displays, and communicate to an indoor sales system; and a mechanical section which (in a self-contained unit) has an electric motor, pumping unit, meters, pulsers and valves to ...
