Abstract
In order to examine the flow motion in a combustion chamber of a motored diesel engine, the variation of instantaneous are velocity at a fixed point in combustion chamber was measured by the constant temperature hot wire anemometer, varing engine speed, shroud shape and shroud position. The results are summerized as follows: 1. The variation of air velocity in a combustion chamber is closely related with the valve timing and piston velocity. 2. The air velocity in the cylinder at suction stroke is being increased and maximized at 60
열선유속계를 이용하여 디이젤 기관 연소실내의 한점에서 유속을 측정한 결과는 다음과 같은 결론을 얻었다. 1. 연소실내의 유동은 cylinder의 원주방향의 속도 성분이 크며, 유속변화는 밸브 timing과 피스톤 속도등에 밀접한 관계가 있다. 2. 유속은 흡입시부터 증가하여 압축행정중 흡입밸브가 닫히는 60
