    摘要： PROBLEM TO BE SOLVED: To provide an engine stably performing zero start even in a four-cylinder engine. SOLUTION: This engine has a plurality of cylinders and first injection valves 3 for injecting first fuel to be combusted in the combustion chambers 2 of the cylinders and comprises second injection valves 4 for injecting second fuel into the combustion chambers 2, which has a heat value and a burning speed larger than the first fuel during burning, ignition plugs 7 installed in the combustion chambers 2 for igniting the injected first fuel and second fuel, pistons 21 reciprocating in the cylinders and dividing the combustion chambers 2 and a zero start control means 60 for starting the engine. In engine starting, in the cylinder in which the piston 21 stops in an expansion stroke, the second fuel is injected into the combustion chamber 2 from the second injection valve and the second fuel is ignited by the ignition plug 7 to carry out an initial explosion and crank the engine for starting.

    摘要： PROBLEM TO BE SOLVED: To provide a control device which controls the timing of premixed combustion. SOLUTION: An internal combustion engine is provided with at least one combustion chamber and a piston which is arranged flexibly sliding within the at least one combustion chamber. The piston is constituted to make a reciprocating motion between a top dead center position and a bottom dead center position. Then, the internal combustion engine is provided with an air supply part and a fuel supply part. The air supply part is fluid-connected to at least one combustion chamber in a selective manner, and the fuel supply part is fluid-connected to at least one combustion chamber in a selective manner. Furthermore, the internal combustion engine is provided with a non-combustion gas supply part and at least one injector which is fluid-connected to at least one combustion chamber and the non-combustion gas supply part. Then at least one injector is constituted to inject non-combustion gas from the non-combustion gas supply part into at least one combustion chamber. COPYRIGHT: (C)2006,JPO&NCIPI

    摘要： PURPOSE:To improve acceleration response and improve fuel consumption by installing an acceleration detecting means onto an engine which uses gasoline and reformed gas and at the same time increasing the feeding amount of reformed gas in acceleration and feeding the lean mixed-gas rather than increasing the amount of gasoline. CONSTITUTION:A mixer 5 and a fuel injection valve 6 are installed in an intake passage 2 of an engine 1. Reformed gas is supplied from the mixer 5 through a fuel tank (methanol-blended gasoline), heat exchanger 10, reforming device 8, gas passage 15, and an electromagnetic valve 16, and gasoline is supplied from the fuel injection valve 6 through a liquid-gasoline passage 19. A control circuit 22 receives a signal from an intake amount sensor 4 and controls the electromagnetic valve 16 and the fuel injection valve 6, and when an acceleration detecting means 20 detects accelerated state, an increased-amount correcting signal is sent into the electromagnetic valve 16 from a correcting circuit 23, and the amount of feed of reformed gas is increased, and the response in acceleration is improved in comparison with the case where the amount of liquid gasoline is increased.
