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...
A fuel pump system suitable for a vehicle engine includes a cam driven piston pump (figure 1, 4) which comprises a pump housing/cambox 9, a flow path provided to allow flow from the cambox directly to a return circuit 17 which incorporates a conduit portion 19 having an aspect ratio of...
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
“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;...

Metal-oxide phase transition of platinum nanocatalyst below fuel cell open-circuit voltage The stability of Pt-based catalysts is critical to the reliability of proton exchange membrane fuel cells. Here, the authors use stroboscopic operando high energy X-ray scattering to reveal Pt nanocatalysts exper...
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 ...
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...
In general, when two filters are used in series, the primary filter retains particles down to about 10 - 30 µm, while the secondary filter is capable of retaining particles greater than 2-10 µm. As fuel systems evolve, clearances and stresses on high pressure components increase and ...
