Abstract

The invention relates to a gasoline engine crankshaft box which comprises a box body, an air cylinder body, a hydraulic tappet, an oil gas separator and an engine oil filter. The air cylinder body isarranged on the box body. The box body is composed of a panel body and a side face body. The side face body surrounds the edge of the panel body. An expansion hole is formed in the bottom of the sideface body. One side of the side face body is provided with an oil inlet, an oil outlet, a pipe connector and an oil receiving disc. The engine oil filter is directly connected with the box body through the pipe connector. The gasoline engine crankshaft box has the beneficial effects that the structure is simple, the manufacturing cost is low, oil gas separation is improved, the sealing performanceis easy to control, the valve clearance does not need to be adjusted, repeated die opening is not needed, few parts are used, the product weight is reduced, and while the use requirement of the function of the product is enhanced, the competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of gasoline engine crankcases, in particular to a gasoline engine crankcase. Background technique [0002] Along with the development of society, various types of motor vehicles emerge in an endless stream, making things convenient for people's life. And most motor vehicles adopt gasoline as fuel, gasoline engine has just become a necessary part of a lot of motor vehicles, and gasoline engine crank case is a core component in the gasoline engine. Its function is to accommodate and support all the parts in it, to ensure the correct position between them, so that the various parts can operate and work in harmony with each other. [0003] However, there are following defects and deficiencies in the crankcase body of the prior art: [0004] First of all, when the gasoline engine is running, the gas (that is, the leakage gas) enters the crankshaft space from the cylinder. The leakage gas contains unburned heat ...
