摘要： A valve operating device for an internal combustion engine is capable of increasing a negative valve overlapping duration when maximum lift amounts of an intake valve and an exhaust valve are small. The valve operating device is provided with intake-side and exhaust-side characteristic adjustment mechanisms for adjusting operating characteristics of an intake valve and an exhaust valve. Each characteristic adjustment mechanism has a control cam rotating integrally with a cam shaft, an electric motor that causes a holder pivoted on the cam shaft to rotate about the cam shaft, a sub-rocker lever pivoted on the holder and caused to oscillate by the control cam, and a valve cam that is caused to oscillate around the cam shaft by oscillation of the holder and the sub-rocker lever, for causing oscillation of main rocker levers. The electric motor causes the holder to oscillate in such a manner that the valve open timing of the intake valve is retarded as a maximum lift amount of the intake valve becomes smaller and the valve close timing of the exhaust valve is advanced as a maximum lift amount of the exhaust valve becomes smaller.

The throttle controlling mechanism controls an opening degree of a throttle valve to fully open the throttle valve at a predetermined load Da with an increase in an operating amount D in a first load range Fa which covers load range below the predetermined load Da in a low-load range, and to keeps the throttle valve fully opened in a second load range Fb which covers a load range over the predetermined load Da. The valve characteristic varying mechanism controls the engine output by controlling the overlap period Pa or the non-overlap period Pb according to the required amount D over the entire load range, and controls valve operation characteristics to obtain a maximum internal EGR rate at the predetermined load Da.

摘要： A variable valve characteristic mechanism has a valve operation cam pivotally supported on a camshaft and a driving mechanism rocking an interlocking mechanism around the camshaft, the interlocking mechanism rocking the valve operation cam by a driving cam integrated into the camshaft. The engine valve starts to open and close in a damping portion of the valve operation cam, and the driving mechanism rocks the valve operation cam via the interlocking mechanism, thereby controlling an opening timing and a closing timing of the engine valve. A cam swelled portion of the driving cam has a constant velocity portion in which a lift velocity is constant, and the constant velocity portion is provided over an angular width where the opening timing in a most advanced angle position of the opening timing of the engine valve and the opening timing in a most retarded angle position of the opening timing are included.
