Title:
FOUR-CYCLE ENGINE FOR OUTBOARD MOTOR
Document Type and Number:
Japanese Patent JP3963084
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve an operating resposiveness of a valve timing variable mechanism, enhance a layout property of an engine, reduce in size, and reduce in cost.
SOLUTION: This four-cycle engine for outboard motor is vertically installed in a state such that a crankshaft and a can shaft 32a are provided in a vertical manner. In the four-cycle engine for outboard motor, a cam shaft driving mechanism 51 which transmits rotation of the crankshaft to the can shaft 32a and a oil pump 70 for lubrication are arranged to a lower side of the engine, and the valve timing variable mechanism 85a and a valve timing control mechanism 84 which receives oil supply from the oil pump 70 to control the valve timing variable mechanism 85a are provided. The valve timing control mechanism 84 is arranged near a lower side of an outside wall (for example, a ceiling surface of a head cover 24) of a valve system chamber 35 in which the cam shaft 32a is built. Further, the valve timing variable mechanism 84 is arranged to a lower end side of the cam shaft 32a and under the cam shaft driving mechanism 51.
