Abstract: PURPOSE: An abrupt change of engine torque in transferring control of driving mode of a gasoline direct injection engine is prevented, thereby improving drivability. CONSTITUTION: In a gasoline direct injection engine having driving mode of early homogeneous mode(EHM), early stratified mode(ESM), and late stratified mode(LSM), a first transferring control is started from above driving mode to a lean air fuel ratio of relative small fuel amount. It is decided whether a corresponding output value of next driving mode is same with a measured output value concerning to opening degree of an exhaust gas recirculation valve or an intake flow control valve. If then, an electronic signal is changed to change the driving mode.

Abstract: PURPOSE: A two-cycle engine is provided to improve mixing property and burning property of a combustion chamber, and to prevent waste of fuel. CONSTITUTION: Air inputted through a throttle body(11) is transferred to a combustion chamber(3). The air is compressed by a piston. Herein, fuel is sprayed from an injector(4) for corresponding to the air sucked in a closed state of an exhaust port(6). In case of mixed air compressed for a specific pressure by closing a scavenging port(2), an ignition plug(5) is operated. By burning the mixed air at a place near a piston top dead center, the piston is lowered. Then, the scavenging port and the exhaust port are simultaneously opened to conveniently exhaust combustion gas by the air inputted through the scavenging port. Therefore, charging efficiency of the sucked air is improved.
