Chapter 10 Engine working conditions and features Section 1 Working conditions &rated powe 2.Engine Rated Power Operation of the engine maximum power allowed is a certain limit.According to the characteristics,application,use features and life requirements of the engine,on the basis of repeated experiments,the power is determined by man. The same type of engine,in different conditions and life requirements,the rated power and corresponding speed on the nameplate can be different.The rated engine power on the nameplate,is allowed to use maximum power called the rated power. China's national standard sets the engine rated power that is divided into the following four grades: (1)15min power:In standard environmental conditions,the maximum effective power allows the engine to operate continuously for 15min. (2)Ih power:In standard environmental conditions,the maximum effective power allows the engine to operate continuously for 1h. (3)12h power:In standard environmental conditions,the maximum effective power allows the engine to operate continuously for 12h. (4)continuous power:In standard environmental conditions,the maximum effective power allows the engine to operate continuously for a long time 机械电子工程学刀 Automobile and Tractor Northwest A&F UniversityAutomobile and Tractor Northwest A&F University Chapter 10 Engine working conditions and features 2.
