Abstract

The invention discloses a four-stroke gasoline engine for combustion and lubrication by using mixed oil fuel. The four-stroke gasoline engine comprises a gasoline engine body, the gasoline engine bodycomprises a cylinder body, a valve chamber, a cam chamber, a crankshaft chamber and a piston cavity are arranged in the cylinder body, the valve chamber, the cam chamber, the crankshaft chamber, thepiston cavity and a combustion chamber communicate in sequence, the valve chamber is located at the top of the cylinder body, a valve rocker, a valve spring, a push rod, an intake valve and an exhaustvalve are installed in the valve chamber, a cam gear and a rocker shifting block are installed in the cam chamber, the cam chamber comprises a cam chamber upper channel, an air storage chamber and acam chamber lower channel, the cam chamber lower channel is in communication with the crankshaft chamber to form a power chamber, a crankshaft is installed in the crankshaft chamber, an air inlet andan exhaust port are further formed in the cylinder body, the air inlet is connected with an air inlet channel, the air inlet channel is in communication with the air inlet valve to form an air inlet airflow forming chamber, the exhaust port is connected with an exhaust channel, and the exhaust channel is in communication with the exhaust valve to form an exhaust airflow chamber.

Description

technical field [0001] The invention relates to the technical field of four-stroke gasoline engines, in particular to a four-stroke gasoline engine burning and lubricating with mixed oil fuel. Background technique [0002] The existing four-stroke gasoline engine has many moving parts, and most of them use a special lubricating oil tank in the crankcase to lubricate the moving parts of the gasoline engine by splashing or forcing. The quantity is inconsistent, and the structure of the four-stroke gasoline engine is complicated and the weight is large. Also cause the use state of gasoline engine to be limited, can not carry out large-scale inclination and overturn in use. [0003] The existing two-stroke gasoline engine adopts mixed lubrication, that is, gasoline and engine oil are mixed according to a certain ratio and stored in the fuel tank for use by the gasoline engine. After the carburetor is atomized, the mixed oil enters the crankcase to lubricate moving parts and ent...
