| 内容記述 | The performance of diesel engine is greatly influenced by the characteristic of fuel pump. The present experiment fixed two factors selected out of the feed oil pressure, engine revolution and effective stroke of used small-sized diesel engine under 85 percent load shown by the developed power of propeller law, and changed the condition of the other. Then, an examination of relation between the discharged ratio (the ratio of practical discharged quantity to theorical discharged one in fuel pump) and the engine performance clarified the following things: (1) When the engine revolution and the effective stroke were fixed under 85 precent load and the feed oil pressure was lower and lower below atmospheric one, the discharged ratio reduced almost hyperbolically. As a result, the fuel injection period was shorter and the specific fuel consumption was better. (2) When the feed oil pressure and the effective stroke fixed in the same way and the engine revolution was lower and lower, the discharged ratio increased for a while and decreased afterward. As a result, the ignition point was faster and the maximum pressure and the rising rate of pressure increased abruptly. (3) When the feed oil pressure and the engine revolution were fixed in the same way and the effective stroke was shorter and shorter, the discharged ratio increased abruptly and the shape of the plunger head caused the ignition time to be late. Then, the indicated specific fuel consumption was better, while the effective specific fuel consumption was worse because of the lowering of the mechanical efficiency. | |||||||||||
