利用一台缸径为240mm的单缸柴油机,试验了燃油预喷对集油机工作性能的影响,着重研究了预喷对改善燃烧、燃烧噪声、废气排放和燃料消耗率的影响。
A single-cylinder diesel engine with cylinder diameter of 240mm was used to test the influence of fuel pre-injection on the operating performance of oil collectors. The effects of pre-injection on improving combustion, combustion noise, exhaust emissions and fuel consumption were studied emphatically.
