Abstract

본 발명은 왕복형 내연기관에 속한다.The present invention belongs to a reciprocating internal combustion engine.

종전의 엔진이 피스톤과 크랭크축이 일직선상에 있을때 연소최고 압력을 가짐으로 엔진에 과대한 기계적 부담만 주고 열효율 및 일효율이 떨어진다.Conventional engines have the highest combustion pressure when the piston and crankshaft are in line, giving the engine an excessive mechanical burden and reducing thermal and work efficiency.

본 발명에서는 상사점이후 회전모멘트가 큰 지점에서 점화를 하여 열효율 및 일효율을 높인다. 따라서 중저속의 큰힘이 요구되는 선박, 중장비, 버스등에 사용 적합하다.In the present invention, the ignition is performed at a point after the top dead center where the rotation moment is large, thereby improving thermal efficiency and work efficiency. Therefore, it is suitable for use in ships, heavy equipment, buses, etc. that require high and low speeds.
