不同负荷下喷射时刻对重油发动机性能的影响
Influence of Injection Timing on Engine Performance of a Heavy Fuel Engine Under Different Loads
摘要
Abstract
Experiments were carried out to research the influence of direct injection timing on engine power,fuel consumption rate and exhaust temperature of a 2-stroke heavy fuel engine based on AADI system under different loads of part loads and heavy loads.The experiment result show that:under part loads,with the injection timing advances,the engine power increases,and the fuel consumption rate and the exhaust temperature decrease accordingly.Under heavy loads,with the injection timing advances,there are several unsteady working conditions which can not affect the pattern,the engine power increases firstly,and then decreases,and the fuel consumption rate and exhaust temperature de-creases firstly,and then increases,and there exists a large range of adjustable injection timing angle.关键词
