Engine cylinder block structure and engine with engine cylinder block structure

Abstract

The invention provides an engine cylinder block mechanism which comprises an engine cylinder block and deep skirt structural bodies arranged on the two sides of the bottom of the engine cylinder block. The deep skirt structural bodies on the two sides are respectively provided with a first hollow structure, and lubricating oil returning channels are formed both in the first hollow structures. Compared with an engine cylinder block mechanism with solid deep skirt structures in the prior art, in the engine cylinder block mechanism, the weight of the cylinder block is lightened, cost is lowered, vibration and noise generated in the operating process of the engine can be lowered, the level of the vibration and the noise is controlled within an ideal range, and the service life of the engine is prolonged. In addition, the hollow structures and the oil returning channels used for oil and gas balance are integrated together. Backflow of lubricating oil to an oil bottom shell in the operating process of the engine can be achieved, free flowing of oil and gas is achieved, and the purpose of oil and gas balance of the cylinder block is achieved. The invention further provides the engine which comprises the engine cylinder block structure.

Description

technical field [0001] The present invention relates to the technical field of engine production, and more specifically, relates to an engine cylinder mechanism, and also relates to an engine having the above-mentioned cylinder mechanism. Background technique [0002] The cylinder block is the largest single component in the engine. It is basically a metal body. In order to achieve the purpose of lubrication and cooling, the cylinder block is equipped with a cylinder combustion chamber, a lubricating oil passage and a cooling water passage. Moreover, an oil filter and an oil cooler, a water pump, and other auxiliary components are installed on the side of the cylinder block. [0003] Since the cylinder body of the engine is subjected to very complicated stress conditions when the engine is working, especially for high-power engines, its working condition is even worse. Therefore, it is necessary to ensure that the cylinder body has a certain structural rigidity and strength....

AI Technical Summary

Problems solved by technology

However, the engine block of the existing deep skirt structure is a solid structure, the block is relatively heavy, and the cost is high

[0004] In addition, due to the limited layout space of the engine block, it is not convenient to specially arrange the oil return passage for oil and gas balance on the cylinder block, and the problem of oil and gas balance is difficult to solve
