Horizontal engine supercharger assembly

Abstract

The invention discloses a horizontal engine supercharger assembly, comprising a cylinder body, a cylinder cover, an exhaust pipe and a supercharger, wherein the cylinder cover is arranged at the top of the cylinder body in a covering way; the exhaust pipe is fixed on the cylinder cover and is provided with a supercharger mounting straight section; the supercharger is located at the rear end of a horizontal engine and is fixed on the supercharger mounting straight section. The horizontal engine supercharger assembly is simple and reasonable in structure, the supercharger is fixed on the cylinder cover by the exhaust pipe at the straight section, the cantilever, supporting the supercharge, of the exhaust pipe at the straight section is short, the supercharger is effectively fixed and supported, and the problem that the exhaust pipe is easily cracked as the supercharge is independently supported by the exhaust pipe is avoided; the postposition connection of the supercharger and the cylinder cover of the engine is realized by the exhaust pipe at the straight section, the total width of the engine body of the horizontal engine is reduced by the supercharger arranged at the rear position, and the total height of the engine can be reduced through fixing the supercharger by the exhaust pipe at the straight section.

Description

technical field [0001] The invention relates to the field of engines, in particular to a horizontal engine supercharger integration. Background technique [0002] A supercharger is an air compressor that increases intake air by compressing air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder, and the pressure and density of the air increase to burn more fuel. Increase the fuel volume and adjust the engine speed accordingly. , in order to achieve the purpose of increasing the engine output power. [0003] The supercharger is usually arranged on the exhaust side of the cylinder head of the in-line vertical ...

AI Technical Summary

Problems solved by technology

[0003] The supercharger is usually arranged on the exhaust side of the cylinder head of the in-line vertical engine, because the height of the engine compartment of some cars is limited, and the vertical engine cannot be arranged

In order to reduce the height of the whole machine, the engine can be changed to a horizontal inclined arrangement. If the supercharger is arranged on the exhaust side of the engine cylinder head when the engine is horizontally inclined, the overall width of the engine will be greatly increased, while the width of the engine compartment of the whole vehicle is limited. will cause the engine to fail to deploy

[0004] Therefore, it is necessary to arrange the supercharger at the rear end of the horizontal engine, and when the rear supercharger is arranged at a high position, such as figure 1 As shown, on the one hand, the exhaust pipe 1 needs to form an arc-shaped extension section 11 to fix the supercharger 2 to the cylinder head 21. When the exhaust pipe of the arc-shaped extension section 11 is connected to support the supercharger, the cantilever is too long It is easy to break, and on the other hand, the height of the engine compartment of the whole vehicle cannot meet the layout requirements, so the rear supercharger needs to be arranged at a low position

The post-mounted supercharger needs to be arranged at a low position, and the oil return angle of the supercharger’s oil return port is too small, and the oil return height drop is insufficient, resulting in poor oil return and degassing effect of the supercharger, and poor oil return, resulting in leakage.
