Abstract

The invention discloses an internal combustion engine. A main structure of the internal combustion engine comprises a cylinder body, a cylinder head , a piston, an intake rectification-injection lip for a combustion chamber, a fuel injector or a spark plug, wherein the intake rectification-injection lip of the combustion chamber is arranged in a combustion chamber; an intake valve seat is arranged on the intake rectification-injection lip of the combustion chamber; the protruding height of the intake rectification-injection lip of the combustion chamber is higher than the surface area of the combustion chamber adjacent to the intake rectification-injection lip of the combustion chamber; and gas passes the intake rectification-injection lip of the combustion chamber from an intake valve and then enters the combustion chamber and the inside of a cylinder.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an internal combustion engine whose combustion chamber is provided with a combustion chamber intake rectification injection lip [0002] The internal combustion engine has at least one intake passage and an intake valve, at least one exhaust passage and an exhaust valve, wherein the intake valve and the exhaust valve are arranged on opposite sides of the combustion chamber, and the combustion chamber intake rectification injection lip It is arranged in the combustion chamber of the internal combustion engine, and the intake valve seat is arranged on the intake rectifying injection lip of the combustion chamber. Background technique [0003] The internal combustion engine that injects fuel by the fuel injection valve, in order to improve the degree of mixing of fuel and air in the combustion chamber, so that the gas flowing into the combustion chamber generates a swirl flow in the ...
