Product Description
PHF4D Series Diesel Engine is an In-line, four-stroke, water-cooling high-speed diesel engine with a direct-injection combustion chamber. This series is a new generation product of a domestic diesel engine of the same type designed by Ricardo in Britain for China and jointly developed with Power HF Co., Ltd.. The machine enjoys good dynamic property, economical efficiency and superior start performance. It can start smoothly without preheating measures when the environment temperature is no lower than -10℃. The top overhaul period is 8000 hours. Its reliability and service life have reached the advanced level among like products worldwide.PHF4D Series Diesel Engine matches, optimizes and customizes the engine and the assembly according to the assembly configuration and the actual use; it has good supporting adaptability with multiple options for flywheel, flywheel housing and alternator available
