Abstract
A simulation model of a turbocharged diesel engine has been set up on an analog computer for studying the performance under transient load conditions. The method uses simplified compressor and turbine characteristics and empirical relationships for the engine thermodynamics. Steady-state results and transient responses for various load changes are compared with corresponding results from a similar digital model and with test-bed results where available.
Proposed improvements to the analog model include the transfer of the compressor and turbine characteristics to the digital section of a hybrid computer which will allow a considerably better representation of the turbocharger to be obtained.
