On a Method of Calculating Characteristics of Exhaust Gas Turbo-Charged Two-Stroke Diesel Engine

The matching of exhaust turbo-charger with diesel engine has important effects on the performance of exhaust gas turbo-charged diesel engine. To determine the matching conditions we presented a method of computation by an electronic digital computer based on the characteristics of exhaust gas turbine and turbo-blowers which were obtained from each experiment. The calculated results for the cycle in the cylinder, the variation of exhaust manifold pressure and temperature and the performance of engine were much the same as the results obtained on the practical engines. It was also made clear that the optimum turbine nozzle area varied with the total efficiency of turbo-charger.
