Two-stroke engine

Abstract

The invention provides a two-stroke engine and belongs to the technical field of engines. It solves the problems of low transmission efficiency and lubricating efficiency of the existing engine. The two-stroke engine includes a crankcase, the outer wall of the crankcase is connected with an oil pump and an intake valve seat, one end of the oil pump is connected with an oil inlet pipe, and one end of the intake valve seat is connected with a carburetor, and the intake valve seat is connected with the intake valve seat. The carburetor is connected, one end of the oil inlet pipe is connected with the intake valve seat, a crankshaft is arranged in the crankcase, a worm wheel is connected to the pump shaft of the oil pump, a worm is set on the crankshaft, and the crankshaft and the worm are fixedly connected. The worm and the worm gear mesh with each other, and both the worm gear and the worm gear are arranged in the crankcase. The two-stroke engine can improve the lubricating efficiency of the two-stroke engine.

Description

technical field [0001] The invention belongs to the technical field of engines and relates to a two-stroke engine. Background technique [0002] During the operation of the two-stroke engine, the mixed gas of engine oil and gasoline needs to be mixed with each other, and the mixed gas is sprayed into the crankcase, enters the cylinder through the scavenging port for compression, and is ignited by the spark plug to push the piston to realize the operation of the engine. In the process of starting the engine, lubricating oil needs to be continuously added, but the proportion of lubricating oil in the manual ratio is certain, which will cause poor lubrication at high speeds, and accidents such as cylinder swelling and shaft locking will occur; small throttle, low speed and idle speed There is too much lubricating oil, poor combustion and easy carbonization; the mixed oil is easy to gel and block the metering hole, making the mixed gas too thin. This causes serious damage to th...
