DEVELOPMENT OF A REAL-TIME DIGITAL COMPUTER SIMULATION OF A TURBOCHARGED DIESEL ENGINE

A quasi-steady-state model of the diesel engine-governor and fuel pump-turbocharger system is described in terms of engine and load dynamics, governor/fuel pump characteristics, air mass flow balance, engine power output, turbine inlet temperature, compressor characteristics and efficiency, turbine swallowing capacity and efficiency, bearing power loss, pulse factor, turbocharger dynamics, and smoke. Real-time digital computer simulation of the turbocharged diesel engine for investigating transient response is discussed. Real-time digital operation is achieved by using an analog computer as a real-time clock and as a signaling device. To the author's knowledge, this is the first such simulation of the turbocharged diesel. Good agreement between predicted and test bed transient results is shown.
