We realized to exploit program systematically will help to decrease the possibility of accidents from the endurance and reliablity researches and tests.The target to promote the completion of the engine structure lies on reducing the occurrence of accident during using,making sure the engine work unfailingly ,extending its life span,on the aspect of structure design,analytical study,manufacturing technique life span management and so on.To improve to reliability,the research have to begin with the factor affecting the life span of the engine and reliability and the action towards them. |
