Abstract: A multi-cam electric valve mechanism for engine is disclosed, which comprises: a motor fixed on a cylinder; a motor shaft wherein one side of it connected to the motor and rotated accordingly and the other side of it symmetrically provided with a plurality of rotors whose shafts are perpendicular to the motor shaft; a ring-shaped cam with a plurality of wave-shaped grooves on the circumference thereof corresponding to the rotors and for setting same; a rotation-stopping lever connected to the cylinder and cam respectively to let the cam linearly move along with it; and a valve lever wherein one side of it connected to the cam and the other side of it connected to a valve.

Abstract: A lubricant device of four-stroke engine is provided according to the present invention. The lubricant device is applicable to a four-stroke engine having a cylinder, a crank case, a rocker arm room and a cam room connected to the rocker arm room. The lubricant device mainly has the rocker arm room and the crank case be connected to each other, and the design of alternating oil supply and oil recycling channels enables lubricant mists to cycle from the crank case through the rocker arm room to the cam room, and then be re-absorbed into the crank case, thereby allowing engines to be manipulated at various angles.

Abstract: A lubricating device for four-stroke engine consists of a cylinder block, a crankcase, an oil sump, a piston, a crankshaft, a connecting rod and an oil dipper, the crankcase contains an upper crankcase body and a lower crankcase body, the bottom of the crankcase extends downward to form an oil trough with a hole in it, an oil dipper is able to operate in the oil trough, an oil box is formed for oil containing by the lover crankcase body and the oil sup, when an engine is running on a normal inclination, a shall amount of oil can only get into the oil trough through three hole in it, movement of the oil dipper atomizes the oil to provide lubrication, if the engine is running on an abnormal inclination or bumping condition, oil will not flow into the crankcase, and this design is able to ensure nor-al operation of an engine on any inclinations.
