Five-cylinder integration compound engine cylinder

Abstract

The invention discloses a five-cylinder integration compound engine cylinder which comprises an engine cylinder body. An I-shaped piston is arranged in the engine cylinder body. A cylinder chamber wall is fixedly arranged in the engine cylinder body and makes contact with the concave portion of the I-shaped piston, so that a cylinder chamber B and a cylinder chamber C are formed. An air cylinder ring is arranged at the lower end of the inner side of the engine cylinder body, and the cavity between a piston ring and the air cylinder ring is used as a cylinder chamber D. The cavity between the top surface of the I-shaped piston and a top cover of the engine cylinder body is a combustion chamber. A cylinder chamber A is located on the lower portion of the engine cylinder body. The five-cylinder integration compound engine cylinder is simple in structure, reasonable in design, convenient to maintain and repair and good in working stability, and production cost is reduced. Impurities in air can be filtered out, damage to an engine is reduced, and service life is prolonged. The working efficiency is high, the power is large, the working temperature is not excessively high, the service life of engine oil is long, and therefore the engine oil replacement frequency is reduced, the aging speed of the piston is low, the service life of the piston is prolonged, and using cost is lowered.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a five-cylinder integrated composite engine block. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy. It has experienced three development stages: steam engine, external combustion engine and internal combustion engine. Internal combustion engines generally convert chemical energy into mechanical energy. The engine is not only applicable to the power generation device, but also refers to the whole machine including the power device (such as: gasoline engine, aero engine). Most modern engines are internal combustion engines. There are many types of internal combustion engines, and common gasoline engines and diesel engines are typical internal combustion engines. [0003] The current engine has a complex structure, high manufacturing cost, poor stability during work, and is prone to failure. High-power engines ge...

Problems solved by technology

[0003] The current engine structure is complicated, the production cost is high, and the stability is not good when working, and it is prone to failure

High-power engines generally use turbocharging to increase the intake air volume of the engine, thereby increasing the power and torque of the engine. However, after supercharging, the pressure and temperature of the engine during work are greatly increased, so the engine life It will be shorter than an unsupercharged engine with the same displacement, and the mechanical properties and lubrication properties will be affected
