Test Research on Water Cooled Diesel Engine's Optimum Work Temperature

This paper puts forward the concept of water cooled diesel engine's optimum working temperature and creates the mathematic model for searching the temperature,improving engine's economic,dynamic performances,and decreasing engine's noise level.It creates the engine performance computing and comparing model on optimum and actual temperature,gives the test method for searching the optimum temperature,at the same time,carries out the relating test aims at the diesel engine WD615.67,finds its optimum temperature,and also gives the comparing results of the engine performance on optimum and actual working temperature.
