Based on D114 series diesel engine main system working principle of the research, we can make the engine work process has thorough knowledge, help us to solve the problems of diesel engine. D114 series diesel engine common and typical fault symptom: a diesel engine can not rotate or move too slowly, a diesel engine can not stop, warm snub operation instability, oil pressure is too high or too low, excessive consumption of machine oil, coolant temperature is too hi gh or too low, coolant loss excessive or severe pollution, oil pollution, exhaust pipe show fuel or oil, load of black smoke for diesel engine, diesel engine power shortage, flameout of diesel engines, diesel engine knock, the high fuel consumption of diesel engine, diesel severe shock or noise is too large, the engine is not adequate or inadequate charging electric, diesel engine crankcase air volume, air compressor press elevated slow the preheating plug, cold starting auxiliary device failure. Keywords: Diesel Engine; five system of typical fault symptom; fuel system. 目录 第1章引言………………………………………………………………………… 05 1.1概述..…………………………………………………………………………...05 1.2课题研究的意义……………………………………………………………06 1.3小结……………………………………………………………………………...07 第2章D114
