Automobile engine piston assembly

Abstract

The invention relates to the technical field of automobile parts, in particular to an automobile engine piston assembly. The automobile engine piston assembly comprises an air cylinder, a piston is slidably connected to the right side inside the air cylinder, a crankshaft is arranged on the left side inside the air cylinder, a connecting rod is rotationally connected between the crankshaft and thepiston, a first rotating shaft is fixed on the crankshaft, a first movable block is rotationally connected on the upper part of the first rotating shaft, a first fixed block is fixed to the left sideof the inner wall of the air cylinder, a second fixed block located on the right side of the first movable block is fixed on the inner wall of the air cylinder, and circular rings are fixed to the sides, opposite to the first fixed block, of the second fixed block. The automobile engine piston assembly has the beneficial effects that the compression ratio of an engine is adjusted by adjusting thedistance between the piston and the right side of the inner wall of the air cylinder, the fuel economy of the engine is improved, the first movable block and a second movable block are arranged so that the crankshaft can stably rotate when in a working state, and a first fixing rod, a second fixing rod and balls are arranged, so that movement of the first movable block and the second movable block is facilitated in an auxiliary mode.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile engine piston assembly. Background technique [0002] The car engine is the machine that provides power for the car, and it is the heart of the car, which affects the power, economy and environmental protection of the car. According to different power sources, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. Traditional engines usually have non-adjustable compression ratio, and it is difficult to give full play to the performance of the engine with a fixed compression ratio. When running at low load and low speed, the thermal efficiency of the engine is very low, and a larger compression ratio can be used. When the load runs at high speed, it is easy to deflagrate and generate a large mechanical and thermal load. To solve the above problems, the invention provides a piston assembly for an automo...

Traditional engines usually have non-adjustable compression ratio, and it is difficult to give full play to the performance of the engine with a fixed compression ratio. When running at low load and low speed, the thermal efficiency of the engine is very low, and a larger compression ratio can be used. When the load is running at high speed, it is easy to deflagrate and generate a large mechanical and thermal load. In view of the above problems, the invention provides a piston assembly for an automobile engine
