摘要： An internal combustion engine comprises a fuel injection valve which has a needle, wherein a valve opening speed of the needle during post injection is raised as compared with a valve opening speed of the needle during main injection if a pressure of the fuel is not more than a first predetermined pressure, while the valve opening speed of the needle during the post injection is lowered as compared with the valve opening speed of the needle during the main injection if the pressure of the fuel is not less than a second predetermined pressure that is a pressure larger than the first predetermined pressure, when a requested post injection fuel amount is larger than an injection amount threshold value.

摘要： An engine fuel control system includes a fuel metering valve operable to control the flow of fuel between a supply line and a delivery line. The delivery line is configured to receive fuel from one or more fuel pumps. The engine fuel control system further includes a pressure raising arrangement which receives the fuel flow from the delivery line and raises the fuel pressure therein. The engine fuel control system further includes a pressure sensor arranged to sense the pressure of the fuel in the supply line between the one or more fuel pumps and the fuel metering valve, or to sense the pressure of the fuel in the delivery line between the fuel metering valve and the pressure raising arrangement.

摘要： An improved device, system and/or method for modulating fuel injection rate through fast magnetostrictive actuation is provided. A fluidomechanical coupler uses fluid to operably couple a magnetostrictive element and a needle element. The fluidomechanical coupler permits the needle element to move from a closed position to an open position when the magnetostrictive element is actuated from a default length to an expanded length. The fluidomechanical coupler is configured to translate an input force into an output response in a direction opposite the input force. The fluidomechanical coupler includes input shafts each within an input bore and positioned adjacent to the magnetostrictive element, a movable output shaft within an output bore and positioned adjacent to the needle element, and fluid passageways connecting input bores and the output bore. Displacement of the fluid between the input bore and the output bore applies or removes a force on the output shaft.

摘要： A fuel injection device is used in an internal combustion engine having a combustion chamber partitioned by a cylinder head, a cylinder, and a piston crown surface so that at least one of the amount of NOx, Pmax, and a thermal efficiency η is maintained at a predetermined value. The fuel injection device includes a fuel injection change unit. The fuel injection change unit virtually divides the combustion chamber into N number of combustion zones where N is a natural number of 2 or more, and can change a fuel injection method according to the respective combustion zones. The fuel injection change unit divides the combustion chamber into the N number of combustion zones, thereby being capable of eliminating a difference of heat in the respective combustion zones, and precisely controlling an in-cylinder pressure P in the combustion chamber. As a result, the amount of NOx and the thermal efficiency can be optimized. Therefore, both of a reduction in the amount of NOx and the high thermal efficiency can be achieved.

摘要： An injector comprising one or more piezoelectric driving stacks wherein a flow control member of the injector is driven directly by the one or more piezoelectric stacks without additional amplification means or interposing elements while a flow area of the nozzle is variably adjustable to deliver controlled flow rates in a desired flow profile to improve engine performance and reduce emissions. The injector is configured to support required flow rates with minimal linear movement of the flow control member. The injector and drive electronics are configured to deliver higher frequency operation and response with increased operational stability due to minimal response lag.

摘要： An injection control unit of a fuel is provided, which prevents generation of a nozzle deposit of a fuel injector. In a control unit of a fuel injector capable of controlling a lift height that is a distance between a valve body and a valve seat, after start of fuel injection and before end of the fuel injection, after the lift height is controlled to a first height, a period in which the lift height is controlled to a second height which is lower than the first height is provided for a predetermined period. According to such a configuration, when the lift height of the valve body is lowered to the second height after the fuel is injected at the first height, a fuel velocity in the vicinity of an inner wall of an injection port is increased due to an inertial force of the fuel and reduction in an opening area. By a fuel flow at a high velocity, a contamination substance adhering to a wall surface is washed away.
