- A THEORETICAL analysis indicated that a charging air system of exhaust-driven turbo-charger, engine-driven Roots-type blower, and aftercooler would permit increasing the output of the General Motors Model 16-278A 2-srroke-cycle diesel engine from 1600 to 3000 bhp at 750 rpm. Using a mechanism to control engine compression ratio relative to engine output would further improve thermal efficiency at lower loads.Tests with a simulated turbocharged installation proved the accuracy of the analysis. Thermal efficiency from 1500 to 3000 bhp was better than that at the original 1600-bhp rating.Tests are now under way adapting turbo-chargers to the engine and developing manifolding to duplicate the simulated turbocharged operation.
