用一辆农用拖拉机的柴油机进行台架试验。在一台1115单缸柴油机上，经过加装电热塞、增大压缩比和喷油泵直径的改装后燃用M100甲醇燃料，并对改装后的甲醇发动机与原柴油机进行对比试验。试验结果表明：甲醇发动机的动力性比原柴油机高，经济性得到改善；尾气排放中甲醇发动机 NOx平均降低45％，尽管 HC和CO的排放整体比柴油机高，但在大负荷时可以平均降低70％；并且在尾气进行三元催化处理后，可以使 HC和CO排放降低到与柴油机一样。通过试验对比，对甲醇替代柴油的可能提供了理论依据，对柴油机节能减排具有重大意义。

The experiment uses an farm tractor diesel engine to conduct an bench test .To make it burns M100 methanol fuel ,we add a glow plug , enlarge the compression ratio and the diameter of fuel injection pump on a 1115 single cylinder diesel engine , and combine the test research between the methanol engine and the original diesel engine .Results shows that the methanol engine can improve dynamic and economy;The methanol engine can reduce 45%averagely on NO x e-missions;Although HC and CO emissions are higher than the original diesel engine , but the methanol engine also can re-duce by 70%on average in high loads .emissions decreace the same as the original engine's after the tail gas is treated by three-way catalytic converter .According to the research , it provides a theoretical basis that methanol could replace diesel and makes great significance for energy save and emission reduction .
