摘要：The failure of gasoline engines seriously affects the safety of drivers and passengers. It is one of the main reasons for the recall of defective automobile products. In order to study the failure regularity of defective gasoline engine products and obtain the product failure mode, the data of the recall of automobile products caused by the defects of gasoline engine in the past five years were studied by using the Pareto Diagram. The research results show that the key factors for the sub-assembly of gasoline engine defects that lead to the recall of automotive products are fuel supply system, lubrication system and cooling system. The key factors of the failure mode are degradation or loss of function failure modes, blockage and leakage failure modes.
