Abstract
The utility model discloses a crank driving machine oil pump typed motorcycle four-stroke engine. The utility model has a case of an infinite variable speed typed two-stroke engine. The case which is quipped with a crank shaft is connected with a case cover. The case is separately connected with a four-stroke engine and an air guide sleeve. Cylinder heads of the four-stroke engine are connected with the case and the air guide sleeve. Pistons which are arranged in the case are connected with the crank shaft by connecting bars. The crank shaft is connected with oil pumps which are separately linked with the cylinder head and the case. The utility model can resolve the problem that, at the currently existing technology, the rate of consumption of lube is comparatively large and discharge of tail gas is over proof.
