The turbocompound diesel engine has been under development since 1972. Development reached a mature stage following the evolution of three power turbine and gear train designs. In 1978, the Department of Energy sponsored a program for comprehensive vehicle testing of the turbocompound engine. Upon successful completion of the vehicle test program, an advanced turbocompound diesel engine program was initiated in 1980 to improve the tank mileage of the turbocompound engine by 5% over the vehicle test engines. Engine improvements could be realized by increasing the available energy of the exhaust gas at the turbine inlet, incorporating gas turbine techniques into improving the turbomachinery efficiencies, and through refined engine system optimization. This paper presents the individual and cumulative performance gains achieved with the advanced turbocompound engine improvements.
