摘要： Methods and systems for determining an LPG fuel output characteristic of an LPG injector. The output characteristic of the LPG can be determined by calculating a total mass of LPG injected into a canister of known volume by the injector during a plurality of open/closed cycles of the injector. The pressure differential and temperature in the canister can be used in the calculation of total LPG mass along with a gas constant of the LPG and the volume of the canister. The total LPG mass can then be used to determine the mass of LPG injected by the injector during each open/closed cycle.

摘要： A fuel injector for an engine is disclosed. The fuel injector has a plunger disposed within a bore, a nozzle member, a valve needle, a check valve, a spill valve, and a controller. The check valve is movable between a first position at which the valve needle is communicated with the bore, and a second position at which the valve needle is fluidly communicated with a drain. The spill valve is movable between a first position at which fuel flows from the bore to the drain, and a second position at which the fuel from the bore is blocked. The controller moves the spill valve toward its second position and the check valve toward its second position during a downward displacing movement of the plunger. The controller detects an unsuccessful movement of the check valve to the second position, and prematurely halts the current injection event in response to the detection.

摘要： In a method and device for characterising the return stroke of injectors, in particular piezo-injectors of an internal combustion engine provided with a common rail system, when the internal combustion engine is switched off, a constant pressure is dropped in the rail, thereby making it possible to measure the rail pressure and to adjust the injectors by corresponding power. The actuating power is increased until a discontinuity in a temporal progression of rail pressure occurs. The actuating energy applied for said state and a pressure available in the make it possible to measure the return stroke of corresponding injector.

摘要： A valve device and a method directly inject gaseous fuel into a combustion chamber. A rapid response in a simple and compact design is achieved by a piezoelectric, magnetostrictive, or electromagnetic actuator that acts on a transmission device that comprises at least two levers, which are connected in series to increase the lift of the actuator to actuate a valve. An associated sensor device detects the position of a valve element, such that the actuator can be controlled to reduce the free play between the actuator and the valve.

摘要： A method and apparatus for detecting a valve position includes the step of providing a non-actuating alternating current signal (24) to a drive coil signal (22). As a valve plunger (14) moves within the coil, the non-actuating signal changes. By monitoring (26,29) the non-actuating signal a control can predict when the plunger reaches a particular position. This invention thus provides a simplified way of detecting an end of travel position (FIG. 1).
