Abstract: Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.

Abstract: An apparatus and method for controlling fuel injection signals to an engine during a sudden acceleration event. The present apparatus and method includes an electronic controller coupled to the electronically controlled fuel injectors of the engine and operable to recognize a sudden acceleration condition based upon certain sensed conditions associated with the acceleration of the engine. The controller is further operable to increase the pull-in current level and/or the hold-in current level of the fuel injection signals to improve fuel injector performance, fuel consumption, and emissions when a sudden acceleration event is recognized. Shortening the duration of the fuel shots associated with the fuel injection signal helps offset additional electrical power requirements associated with the higher current levels.

Abstract: The present invention provides a fuel injection system and method of operating the fuel injection system. The fuel injection system includes at least one hydraulically actuated fuel injector fluidly connected with a source of high pressure actuation fluid. A viscosity sensor determines the viscosity of the hydraulically actuated fuel injector. A controller in communication with the fuel injector and the viscosity sensor is configured to determine the rate of change of the viscosity of the high pressure hydraulic actuation fluid. The supply of high pressure actuated fluid to the fuel injector is based, at least in part, on the rate of change of the determined viscosity of the high pressure actuation fluid.

Abstract: A method of controlling fuel delivery in an internal combustion engine includes enabling split injection status without subjection to a temperature comparison while the engine operates in the start mode, and enabling split injection status without subjection to a time limit while the engine operates in the idle normal mode, but with subjection to the temperature comparison in the idle normal mode. In the method, a temperature threshold is established, an engine operating temperature is monitored, the engine operating temperature is compared to the temperature threshold. Further, the engine is operated in the start mode, and at that time, the split injection status is enabled without subjection to the temperature comparison. Thereafter, the engine is operated in the idle normal mode, and at that time, the split injection status is enabled without subjection to a time limit while the engine operates in the idle normal mode and the engine operating temperature falls below the temperature threshold to enhance cold temperature operation. Otherwise, when the operating temperature exceeds the temperature threshold during idle normal mode, the split injection status is disabled.
