An altitude fuel limiter and method for controlling an engine using the same is provided. The altitude fuel limiter includes a torque screw sleeve extending from an inboard end to an outboard end. The torque screw sleeve has an interior surface defining a ...

A fuel supply apparatus is designed to secure a high fuel pressure to enhance starting operation efficiency and to respond the requirements of low fuel consumption and power saving at the time of starting operation of a fuel consumption unit such as an int...

Pressure controllers (28,30) open or close the connection of a shunt (24) to a fuel line (18) at a first pressure, and open or close the connection of a return line (22) with the fuel line at a second pressure. The pressure controller open the shunt and th...

A three-way valve (71) is closed and two-way valve (72) is opened during non-injection state, to supply dimethyl ether (DME) fuel from feed pump (5) into aspirator (7). The solenoid valve (75) is opened to connect the fuel tank (4) with inlet of oil reserv...

The arrangement has low and high pressure systems. The high pressure system has a high pressure pump (16) followed at least one high pressure injection valve (20). The low pressure system has a demand-driven fuel pump (12) connected to the high pressure pu...

This invention relates to a fuel injection control system for an in-cylinder injection internal combustion engine. The system is provided with a fuel injection valve (1) arranged at a cylinder for injecting fuel into the cylinder, fuel feed pressure settin...

The thermal treatment device has a hollow chamber (2) inserted in the fuel feed line (3,4,5) for the IC engine, through which the fuel is passed in contact with a heat exchanger surface (6) connected to the engine coolant circuit. An electric heating devic...

A method for monitoring the extent of wear a fuel pump (40) forming part of a fuelling system for an engine (45), comprising the steps of delivering fuel from the fuel pump (40) to a metering valve arrangement (44) for regulating fuel flow from the pump to...

The fuel supply has a fuel tank and fuel pump and/or fuel filter, fuel supply and return lines to the tank and/or engine and a housing. Valves (8-11) that are used to interrupt the flow of fuel in at least one of the fuel lines (4-7) in the event of a cras...
