Abstract: The durability test has been conducted to evaluate the performance of a newly developed engine. According to relative standards， a 600 h durability test has been implemented to examine the power， torque， fuel consumption， piston leakage， cylinder pressure， oil consumption and parts damage. The test data have been used to analyze the changing state and regularity of dynamic， economic， airtight and reliable performance. The durability test indicates that new engine can meet the design and practical requirements. It has provided reference data for engine approval test and follow-up improvement of the same series.
