Abstract: PURPOSE: A gasoline engine system is provided to improve the stability of self ignition combustion by differently controlling the lift amount and timing of first and second intake valves to form uniform mixed gas. CONSTITUTION: A gasoline engine system comprises an injector, a spark plug, intake valves, exhaust valves(120), a variable mechanism, and a controller. The injector is located in the upper center portion to directly inject fuel into a combustion chamber in which a piston is installed. The spark plug is installed corresponding to the injector in order to create direct spark in the combustion chamber. The intake valves(100,110) are installed in an intake port for drawing air into the combustion chamber. The exhaust valves are installed in an exhaust port for discharging the combustion gas of the combustion chamber. The variable mechanism controls the lifting amount and opening degree of the intake and exhaust valves, wherein the lifting amount and opening degree of the intake valves are controlled differently.

Abstract: PURPOSE: A variable compression ratio apparatus is provided to facilitate design and minimize cause of inertial mass increment of a crank web since the design of a connecting rod is only changed without the design change of a crank and a piston. CONSTITUTION: A variable compression ratio apparatus comprises an eccentric bearing, a latching rod(110), a variable plate(200), and an actuator. The inner circumference of the eccentric bearing contacts the outer circumference of the piston pin. The outer circumference of the eccentric bearing contacts the inner circumference of a ring formed at the end of a connecting rod(30). The latching rod can slide inside the piston pin. The variable plates are formed at both lower portions of a cylinder(10), respectively. The actuator rotates the variable plates in opposite directions.

Abstract: A wear measuring method of a clutch disk by using a laser beam is provided to detect the wear of the clutch disk accurately, and to display the replacement time of the disk precisely by irradiating the laser beam to the surface of the clutch disk and receiving diffused light. An engine of a vehicle is stopped(S10), and a laser emitting unit and a receiver unit are turned on after checking stop of the engine(S20). The receiver unit measures diffused light(S30), and a power spectrum analyzes the measured diffused light to gain the frequency of the diffused light(S40). The frequency of the diffused light is compared with the input value(S50). The replacement signal is output in case of the analyzed frequency to be equal to the input frequency value(S60), and data is initialized for the next measurement in case of the analyzed frequency not to be equal to the input frequency value(S70).
