摘要： Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves taht can be calibrated outside of the injector prior to the installation thereof.

摘要： A premixed-charge compression-ignition engine and control system (10) is provided which effectively initiates combustion by compression-ignition and maintains stable combustion while achieving extremely low oxides of nitrogen emissions, good overall efficiency and acceptable combustion noise and cylinder pressures. The present engine and control system (10) effectively control the combustion history, that is, the time at which combustion occurs, the rate of combustion, the duration of combustion and/or the completeness of combustion, by controlling the operation of certain control variables providing temperature control, pressure control, control of the mixture's autoignition properties and equivalence ratio control. The combustion control system (10) provide active feedback control of the combustion event and includes a sensor, e.g. pressure sensor (16), for detecting an engine operating condition indicative of the combustion history, e.g. the start of combustion, and generating an associated engine operation condition signal (18).

摘要： A unitized fuel supply assembly is disclosed including an in-line reciprocating cam driven pump (14) for supplying fuel to an accumulator (12) from which fuel is directed to a plurality of engine cylinders by means of a distributor (16) mounted on the unitized assembly. Dual pump control valves (20) provide fail safe electronic control over the effective pump displacement. One or more injection control valves mounted on the distributor are provided to control injection timing and quantity. The accumulator (12) contains a labyrinth of interconnected chambers (36) which are shaped and positioned to produce a minimum overall package size while providing for easy manufacture.

摘要： A fuel injection rate shaping control system is provided which effectively controls the flow rate of fuel injected into the combustion chamber of an engine to improve combustion and reduce emissions by controlling the rate of pressure increase during injection. The injection rate shaping control system includes a rate shaping control device (10) including a rate shaping transfer passage (22) having a predetermined length and diameter specifically designed to create a desired injection pressure rate shape. In other embodiments of the present invention, two or more rate shaping transfer passages (72, 74) capable of producing distinct rate shapes are packaged in various fuel injection systems to selectively provide various rate shapes depending on operating conditions. Switching valves, i.e. solenoid operated three-way valves (76, 84, 86), may be used to direct the fuel or timing fluid flow to any one of the rate shaping transfer passages. Also, a dampening means in the form of a reverse flow restrictor valve (26) is positioned in the rate shaping transfer passage to dampen reflected pressure waves thereby minimizing the adverse effects thereof.

摘要： Un injecteur (1, 2) de carburant met en oeuvre des sous-ensembles interchangeables (10, 11) qui permettent d'utiliser l'injecteur avec l'option injecteur ouvert ou avec l'option injecteur fermé sans affecter l'installation du moteur, et sans modifier la régulation ou le dosage. L'injecteur (1, 2) de carburant est composé de deux sous-ensembles, un premier sous-ensemble étant un sous-ensemble de régulation et de commande (13) utilisé avec les options à la fois injecteur ouvert et injecteur fermé, et un second sous-ensemble se présentant sous deux versions, une version injecteur ouvert (11) et une version injecteur fermé (10).
