Problems solved by technology

Due to the limited internal space of the engine, especially for high-power engines, the oil pump is usually installed outside the engine. This external oil pump not only affects the compactness of the engine, but also affects the appearance of the engine.
Due to the limited internal space of the engine, the drive gear built into the oil pump is bound to be lower than the liquid level of the oil pan, and the phenomenon of gear stirring the oil will occur. The oil stirring of the gear will cause problems such as high oil temperature, high oil consumption, and high power consumption.

Abstract

The invention discloses an engine and a mounting structure capable of realizing internal arrangement of an engine oil pump and applicable to the engine. A gear chamber of the engine is mounted at the bottom of the engine; the engine oil pump is mounted at the bottom inside the gear chamber and is located below the liquid level of engine oil inside an oil sump of the engine; and a gear working cavity for isolating a driving gear of the engine oil pump from the engine oil in the oil sump is arranged in the gear chamber. Thus, with the mounting structure capable of realizing internal arrangement of the engine oil pump and applicable to the engine, the engine oil pump of the engine can be arranged internally, and the problem that a gear of the engine oil pump stirs the engine oil can be solved.

Description

technical field [0001] The invention relates to the technical field of engines, and more specifically relates to an engine and a built-in installation structure of an oil pump thereof. Background technique [0002] With the rapid development of the engine industry, users not only have higher and higher requirements for its performance, but also put forward higher requirements for the appearance of the engine. Due to the limited internal space of the engine, especially for high-power engines, the oil pump is usually installed outside the engine. This external oil pump not only affects the compactness of the engine, but also affects the appearance of the engine. Due to the limited space inside the engine, the built-in driving gear of the oil pump is bound to be lower than the liquid level of the oil pan, and the phenomenon that the gears stir the oil occurs, and the gears stir the oil, which will lead to problems such as high oil temperature, high oil consumption, and high pow...
