초록

In a diesel engine (1) supercharged by an exhaust gas turbocharger, both the compressor (4) and the turbine (3) of the supercharger are designed for full engine power and speed. A by-pass duct (8) provided with a non-return valve (9) and a control device (10) is connected between the exhaust gas duct (9) and the boost air duct (5). The turbine (3) is equipped with means (11, 12, 13) for varying the turbine equivalent cross-section. At part load, the equivalent cross-section and, simultaneously, the by-pass duct cross-section are varied in order to operat...
