摘要： The invention discloses an internal combustion engine wherein each cylinder includes a main combustion chamber, an intake port opening into the main combustion chamber, an intake valve for opening and closing the intake port, an intake passage communicating with the main combustion chamber through the intake port for charging the lean mixture into a main combustion chamber, a trap chamber with a spark plug, and a fuel injection nozzle disposed in the intake passage and actuatable in response to a signal from a control system to inject a fuel at least one time during the suction stroke, thereby causing a rich mixture to be trapped in a trap chamber to ensure the positive ignition. The fuel is also injected during another stroke other than the suction stroke in which the fuel is completely vaporized, so that the lean mixture, may be charged into the main combustion chamber during the next suction stroke. Thus, the HC emission may be substantially reduced. According to one embodiment of the present invention, the ratio of the quantity of the fuel to be injected during the suction stroke to the total quantity of the fuel to be injected in each cycle of the engine is varied so that the rich mixture (in a minimum quantity but sufficient for ensuring the positive ignition in the trap chamber) may be supplied, as as to further reduce the pollutant emission.
