摘要： Methods are provided for controlling a solenoid spill valve of a direct injection fuel pump, wherein the solenoid spill valve is energized and de-energized according to certain conditions. An example control strategy is provided for operating the direct injection fuel pump when fuel vapor is detected at an inlet of the direct injection fuel pump. To ensure pump effectiveness during the presence of fuel vapor, the solenoid spill valve may be maintained energized for a minimum angular duration past a top-dead-center position of a piston in the direct injection fuel pump.

摘要： In a gaseous-fuel-injector device for internal-combustion motor-vehicle engines, the valve body of the injector device has one or more auxiliary openings giving out onto an internal surface of the valve body in which the valve member of the injector device is slidably mounted. Said auxiliary openings are arranged in such a way as to enable the inflow of the gaseous fuel coming from the supply, not only into the inlet opening of the injector device, but also into the internal area of the valve body in which the valve member is slidably mounted, so as to obtain an effect of ventilation and flushing, by means of the flow of gaseous fuel, in an area where there tend to form deposits of the oily substances contained in the gaseous fuel.

摘要： A discharge valve (30) is provided in a high-pressure fuel passage (31) to allow fuel to pass through the discharge valve (30) only in a direction from a high-pressure fuel pump (20) toward a delivery pipe (50). A communication passage (41) with an orifice (42) is formed integrally with the discharge valve (30) in parallel with the discharge valve (30) to connect areas upstream and downstream of the discharge valve (30). When a fuel pressure in the delivery pipe (50) is increased to a target pressure using the high-pressure fuel pump (20), an amount of the fuel, which does not interfere with an increase in the fuel pressure, flows through the orifice (42). A check valve (40) is provided in the communication passage (41), and opened to allow the fuel to pass through the check valve (40) only in the direction from the delivery pipe (50) toward the high-pressure fuel pump (20), when the fuel pressure is higher than a first predetermined pressure.

摘要： A system and method controls a flow of vent gases to a combustion engine. The system includes an inlet for receiving the vent gases, a pressure relief device that enables the vent gases to escape to atmosphere when a pressure in the inlet exceeds a predetermined relief pressure, a flow-restricting orifice, and a back pressure regulator disposed downstream of the orifice. A shut-off valve disposed between the back pressure regulator and the air intake is set to only open when an intake pressure falls below a predetermined negative intake pressure.
