摘要： By setting a switching timing of switching means that connects either one of a high pressure fuel source and a low pressure fuel source to an injector earlier than a point of time when an injector finishes a high pressure fuel injection, leak fuel or return fuel is reduced and an engine load is reduced and therefore mileage is improved.

摘要： A common-rail injection system includes a first accumulator of high pressure and a second accumulator of low pressure. The common-rail injection system includes a post injection control device for injecting additional low-pressure fuel from the second accumulator through a fuel injection nozzle after main fuel is injected. The post injection control device injects the additional fuel the injection terminates at a first timing when the fuel pressure in either fuel passage or second accumulator lowers to a predetermined value lower than that of the high-pressure fuel or at a second timing when an exhaust stroke of the engine is completed, whichever earlier.

As a result, the dead volume between the second control valve, the check valve and the fuel injection valve is minimized and the responsiveness of fuel pressure control can be improved.

摘要： After an engine has been started, a controller 8 of a fuel injection system opens an injection rate switching change-over valve 5 for a period of time not less than a fuel injection period until the time a fuel pressure in a low pressure accumulator 4 connected to the portion of a fuel passage 10a which is on the downstream side of the change-over valve 5 has reached a set level, whereby a fuel injection starting delay ascribed to a fuel pressure decrease in the second accumulator can be prevented. After the engine has been started, the controller 8 of the fuel injection system sets the change-over valve opening starting time in each fuel injection cycle to the time earlier than the injector opening starting time, or the opening starting time of both an injector and change-over valve to the time earlier than those in a regular mode until the time the fuel pressure in the low-pressure accumulator 4 connected to the portion of the fuel passage 10a which is on the downstream side of the injection rate switching change-over valve 5 has reached the set level, whereby the fuel injection starting delay can be prevented. Therefore, the engine starting characteristics are improved, and the discharging of white smoke from the engine is prevented.

摘要： During a transitional operation of an engine in which an engine load is changed suddenly from a high load to a low load, a control operation for extending an opening period of a change-over valve which is adapted to switch a low-pressure accumulator and a high-pressure accumulator from one to the other during a fuel injection operation is carried out to increase a flow rate of a fuel supplied to the low-pressure accumulator and thereby reduce the pressure in the high-pressure accumulator, whereby a response delay of the fuel pressure in the high-pressure accumulator is minimized. During a transitional operation of the engine in which the engine is in an accelerated operation, the change-over valve is kept open until the fuel pressure in the low-pressure accumulator, which is connected to the portion of a fuel passage which is on the downstream side of the change-over valve adapted to switch the low-pressure accumulator and high-pressure accumulator from one to the other during a fuel injection operation, reaches an indicated level, and until a predetermined period of time elapses after the fuel injection finishing time, whereby the formation of a fuel pressure in the low-pressure accumulator is promoted to obtain injection condition suiting the operating condition of the engine.

摘要： A projection positioned in the center of a concave section of a toroidal combustion chamber is divided into a section with a steep slope extending from the bottom to the head surface and a section with a gentle slope. The head surface is in the form of a flattened conical trapezoid. Because of its shape, the projection makes it possible for the air which is close to the center section to flow close to the surface of a side wall of the concave section. The air which had been at the center section is added to the amount of air supplied for combustion and is mixed with the fuel in the vicinity of the surface of the side wall of the concave section. By setting the angle at which the air flows along the side wall surface (re-entrant angle) in the combustion chamber, the flow of the air close to the side wall surface is made turbulent, which improves the agitation of the fuel.
