| Abstract: | This paper presents a new type of combustion system by impinging slant wall spray in D.I. diesel engine. The macro spray characteristics of impinging close to slant wall of fuel jet were investigated by using of advanced Particle Image Velocity (PIV) on a constant volume vessel. A single cylinder D.I. diesel engine that applies this new combustion system is tested with varieties of plans. The experimental results show that the new type of combustion system has better performances under the middle or low engine load. The even better performances will be obtained by means of further improving designation in actual D.I. diesel engine. |
