A fuel pump driver circuit for an internal combustion engine includes a voltage supply which energizes the fuel pump through an output or switch transistor. The output transistor is turned off to stop the pump by a control transistor, which is controlled by a differential amplifier or switch. ...
The purpose of the Fuel Cooler Pump Control Circuit is to control the operation of the fuel cooler pump. This feature is specific to diesel powered vehicles to cool the excess fuel prior to returning the fuel back to the fuel supply system. The fuel is cooled by the fuel cooler that opera...
“boost pumps” at the motor inlets suppress cavitation in the high-pressure main pumps downstream. The low-pressurefuel pumpis a single-stage, axial-flow (propeller type) design driven by a two-stage reaction turbine powered by gaseous hydrogen drawn from the combustion chamber coolant circuit;...

The hydrogen is primarily supplied to the PEMFC from the high-pressure hydrogen tank; the gas travels through the serpentine, and then, the exceeding part is recovered in a secondary circuit. It is worth noting that the nature of this “recovered” flow, two-phase multispecies, poses one of...
Two stage filter system typically uses a primary filter on the inlet side of the fuel transfer pump and a secondary filter on the outlet side. The primary filter is required to remove larger particles. The secondary filter is required to withstand higher pressures and remove smaller particles ...
Circuit is designed to delay the switching off of the fuel pump should the air metering valve unintentionally close. The cold start valve has a thermal time limiting switch to prevent the engine from being flooded with excess fuel after abortive start attempts. The lead from the ignition switch...
PURPOSE:To control discharge facility of a fuel pump while save electric power at its light load and reduce a noise of the fuel pump, by changing setting voltage of the fuel pump and controlling mean voltage applied to a motor. CONSTITUTION:An inverter amplifier circuit 2, constituted of an ...
Detection of residual gas (especially oxygen) in the fuel gases of a fuel cell, using a gas sensor (1) operating as a pump probe, involves providing an inlet for the external atmosphere, sealed in gas-tight manner from the sensor measuring electrode (4), which includes a solid electrolyte...
There is provided a high-pressure fuel pump drive circuit for manipulating the electric current to be passed to a solenoid coil for controlling a high-pressure pump. This circuit is
