Abstract
A VALVE CHARACTERISTIC VARYING MECHANISM (M) OF A VALVE OPERATION DEVICE (40) CHANGES AN OVERLAP PERIOD AND A NON- OVERLAP PERIOD TO THEREBY CONTROL AN INTERNAL EGR RATE. THE VALVE CHARACTERISTIC VARYING MECHANISM (M) COMPRISES A CONTROL MECHANISM (M3) FOR SWINGING AN INTAKE LINK MECHANISM CONNECTED TO AN INTAKE CAM (53) AND AN EXHAUST LINK MECHANISM CONNECTED TO AN EXHAUST CAM (54) ABOUT A CAMSHAFT (50), AND A DRIVING MECHANISM FOR DRIVING THE CONTROL MECHANISM (M3). THE CONTROL MECHANISM (M3) CONNECTS THE DRIVING MECHANISM WITH THE RESPECTIVE LINK MECHANISMS SO THAT A RETARDED AMOUNT IN AN OPENING TIME OF AN INTAKE VALVE (22) BY THE INTAKE LINK MECHANISM IS GREATER THAN AN ADVANCED AMOUNT OF A CLOSING TIME OF AN EXHAUST VALVE (23) BY THE EXHAUST LINK MECHANISM WHEN ASSUMING THE SAME DRIVING AMOUNT BY THE DRIVING MECHANISM IN A DIRECTION WHERE THE INTERNAL EGR RATE INCREASES.
