Automobile engine

Abstract

The invention relates to an automobile engine comprising an engine body and a valve mechanism arranged on the body. The body comprises a cylinder; a slide block is connected with a piston connecting rod reciprocating in the cylinder; a groove slide way is opened on the outer wall of a rotor meshed with a power output shaft; the slide block is positioned in the groove slide way to form linkage between the piston connecting rod and the rotor; the valve mechanism comprises a valve switch rotating shaft and a valve switch cam which is arranged on the valve mechanism and control the switch of gas inlet / outlet valves; transmission between the valve switch rotating shaft and the power output shaft is realized by means of engagement system. The automobile engine drives the rotor to rotate by the piston connecting rod, has simple rotating structure, low noise, and small size, thereby reducing manufacturing cost and improving output power of the engine.

Description

technical field [0001] The invention relates to the technical field of reciprocating piston internal combustion engines. Background technique [0002] The dual-piston internal combustion engine is a complex machine that converts heat energy generated by burning fuel into kinetic energy. The working cavity of the reciprocating piston internal combustion engine is called a cylinder, and the inner surface of the cylinder is cylindrical. The piston reciprocating in the cylinder is connected with the crankshaft through the connecting rod to form a crank connecting rod mechanism. So when the piston reciprocates in the cylinder, the connecting rod turns the crankshaft, or vice versa. At the same time, the volume of the working chamber is constantly changing from the minimum to the maximum, and then from the maximum to the minimum, and so on. The top of the cylinder is closed with a cylinder head. The cylinder head is equipped with an intake valve and an exhaust valve, and throu...

AI Technical Summary

Problems solved by technology

The in-line engine is simple in structure and cheap in price. The disadvantage is that the engine is taller and longer in length. The disadvantage is that two cylinder heads must be used, the structure is relatively complicated, and the price is relatively expensive; the horizontally opposed engine is generally installed on the center line of the vehicle, and the pistons are evenly distributed on both sides of the crankshaft, moving left and right in the horizontal direction. The torques generated by the pistons on both sides cancel each other out, which greatly reduces the vibration and noise during vehicle operation. The engine speed is greatly improved, the fuel consumption is lower, and the overall height and length of the engine are reduced. However, its technical requirements are very high, and cooling The system is also very demanding and more expensive to manufacture than a V-type engine
