    • An engine lubrication method is provided. The four-cycle engine has an engine block having a cylindrical bore and an enclosed oil reservoir. A crankshaft is mounted in the engine block. An oil pump driven by the cam gear, brings the oil from the oil reservoir and the valve chamber. The engine is provided with a cylinder head assembly having a pair of overhead intake and exhaust valves. A circular arc wall surrounds the web of the crankshaft at a slight distance from the web. The crankshaft web causes the oil to fly to lubricate engine parts and the oil, returns into the oil reservoir by a check valve. Flowing of oil in to the combustion chamber when the engine is oriented to incline is prevented by oil recesses and long pipes. Another lubrication and breathing system without pump is presented, wherein construction except pump is basically followed.

    • The present invention is directed to a four-cycle engine including a lightweight aluminum alloy engine block having a cylindrical bore and an oil reservoir formed therein. A crankshaft is rotatably mounted in the engine block for rotation about a crankshaft axis. A piston reciprocates within the bore and is connected to the crankshaft by a connecting rod. An oil pump driven by the cam gear, which mates with a crank gear that is driven by a crank shaft, inhales oil from the oil reservoir and the valve chamber to splash lubricate into the cylinder bore. The engine is provided with a cylinder head assembly defining a compact combustion chamber having a pair of overhead intake and exhaust ports and cooperating intake and exhaust valves and a circular arc wall which surrounds around webs of the crankshaft so that each crankshaft web splashes and causes the oil to fly to lubricate engine parts.

    • An engine lubrication method is provided. The four-cycle engine has a lightweight aluminum alloy engine block having a cylindrical bore and an enclosed oil reservoir formed therein. A crankshaft is rotatably mounted in the engine block for rotation about a crankshaft axis. A piston reciprocates within the bore and is connected to the crankshaft by a connecting rod. A cam shaft is rotatably mounted in the crank shaft chamber for rotation about a cam shaft axis, parallel to the crank shaft axis.

The engine is provided with a cylinder head assembly defining a compact combustion chamber having a pair of overhead intake and exhaust ports and cooperating intake and exhaust valves. A lightweight, high-powered engine is thereby provided having relatively low HC and CO emissions. A circular arc wall surrounds around web of the crankshaft with a slight distance from the web. A scroll-shaped wall has gradually increased distance from said wall to the direction of rotation of the web and has partial overlap with the circular arc wall. The check valve splashes breathing mist oil from crank shaft room to breather room and causes the oil to supply to lubricate engine parts in valve chamber and the oil, after lubricating the parts, is returned into the oil reservoir.The oil in crank shaft chamber, after lubricating engine parts, is returned to oil reservoir guided by scroll-shaped wall and a hole provided on the scroll-shaped wall.In case of stock of engine oriented power take off side up or down, oil is prevented to flow from oil reservoir to combustion chamber by a weir which is provided between circular wall and scrolled or extended wall.
