【Abstract】 To meet the requirements of fitting a turbocharger on a Model 495Q automotive diesel engine, two turbocharged systems have been designed. The optimal structural parameters of these systems are given. A large amount of calculations and analysis on matching Model K26 turbocharger with Model 495Q diesel engine and a series of tests were carried out. Results show that the data calculated are in good agreement with those obtained in tests. The engine performance has been considerably improved. The rated power output is increased from the original design of 51.5 kW at 2800 r/min to 66.2 kW and the specific fuel consumption is reduced from 258 g/kW·h to 245 g/kW·h.更多还原
