摘要： An internal combustion engine includes: a variable valve train mechanism, configured to receive a cam displacement of an inlet cam so as to vary a driving output for driving an inlet valve continuously from a maximum valve lift to a minimum valve lift so as to match the driving output with a running condition of the internal combustion engine; and a control part, configured to control the variable valve train mechanism so as to set a valve lift of the inlet valve to a starter valve lift when starting the internal combustion engine in a cold state. The starter valve lift is formed so that a valve opening period of the inlet valve is set to encompass an overall area of an induction stroke period of the internal combustion engine from a top dead center to a bottom dead center of the induction stroke period.

摘要： A valve unit of an internal combustion engine is accommodated in a space between a cylinder head and a rocker cover. The valve unit comprises a camshaft, a variable valve operating mechanism, a sensor, and a retaining member. The camshaft is provided with a cam for each cylinder. The variable valve operating mechanism receives a displacement of the cam, outputs a valve drive output, and continuously variable-controls the valve drive output in accordance with a rotational displacement of a control shaft provided substantially in parallel with the camshaft. The sensor detects the rotational displacement of the control shaft. The retaining member retains the camshaft, the variable valve operating mechanism, and the sensor. The retaining member expose the sensor to the out side of the rocker cover thereby to fix the camshaft, the variable valve operating mechanism, and the sensor to the cylinder head.

摘要： A variable valve device of the invention has a structure in which, as connecting means for connecting a movable cam 22 located in an outer periphery of an outer camshaft 17a and an inner camshaft 17b located inside the outer camshaft 17a, there are provided a pin-like member 24 that is movably inserted so as to penetrate the movable cam 22, the outer camshaft 17a and the inner camshaft 17b along a diametrical direction of a shaft member 17 that is formed by turnably encasing the inner camshaft 17b in the outer camshaft 17a, and an escape-preventing portion 50 disposed in the end portion of the pin-like member 24. The movable cam 22 and the inner camshaft 17b are thus connected together while preventing large press-fit load and axial force from acting on components.
