摘要： A split injection of gasoline produces stratified charge in at least one cylinder. A sensor measures cylinder pressure or knock and generates a sensor signal indicative of combustion event timing of stratified charge. From the sensor signal, a controller determines an actual value of a characteristic parameter representing combustion event timing in the cylinder. The controller modifies at least one of operating variables governing a split injection for the subsequent cycle in such a direction as to decrease a deviation between the actual value of the characteristic parameter and a target value thereof toward zero.

摘要： Before warmup of a fuel cell stack (1) is complete, a cooling water pressure of the fuel cell stack (1) is suppressed lower than the pressure used when the fuel cell system is run in the steady state. In this way, when the system is started from a low temperature state, water in a cathode (2) and anode (3) flows efficiently into the cooling water passage (9), and water clogging is prevented while maintaining a proper water balance in the fuel cell system.

摘要： An enhanced auto-ignition in a gasoline internal combustion engine, comprises a fuel injector directly communicating with said combustion chamber for spraying gasoline fuel. The fuel injector sprays a first injection quantity of gasoline fuel into a combustion chamber at first fuel injection timing, which falls in a range from the intake stroke to the first half of the compression stroke, thereby to form air/fuel mixture cloud that becomes a body of mixture as the engine piston moves from the first fuel injection timing toward a top dead center position of the compression stroke, and the fuel injector sprays a second injection quantity of gasoline fuel into the body of mixture at second fuel injection timing, which falls in the second half of the compression stroke, forming mixture cloud that is superimposed on a portion of said body of mixture, thereby to establish the cylinder content wherein the density of fuel particles within the superimposed portion is high enough to burn by auto-ignition at an ignition point in the neighborhood of the piston top dead center position of the compression stroke, causing temperature rise and pressure, which initiate auto-ignition of the fuel particles within the remaining portion of said body of mixture.
