摘要： An engine includes, a cylinder head, an intake valve, an exhaust valve, and a first clearance adjusting mechanism for actuating the intake valve. The first clearance adjusting mechanism (1) maintains a first valve clearance when the intake valve and the cylinder head are in a cold state, such that the intake valve closes after a bottom dead center, and (2) maintains a second valve clearance, shorter than the first valve clearance, when a temperature of the intake valve is in a hot state and a temperature of the cylinder head is still in the cold state, after a cold start of the engine, such that an open timing of the intake valve is advanced and a close timing of the intake valve is retarded. The exhaust valve opens and closes at fixed predetermined timings regardless of a temperature of the exhaust valve and the cylinder head.

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.
