Abstract

PROBLEM TO BE SOLVED: To control an exhaust gas rate and a NOx output in a proper value. SOLUTION: When a turbine 5 is driven by exhaust gas from a diesel engine 1, air is accepted from a silencer 7 to compress by a compressor 6. The compressed air passes an air cooler 9 from an intake pipe 8 to supply to the engine 1. A bypass pipe 11 is connected to the succeeding intake pipe 8 side at the back of the air cooler 9, and is connected to the compressor 6 of a supercharger via the intake bypass valve 12. If the opening of the intake bypass valve 12 is adjusted, the compressed air after cooling can be returned to the supercharger 3 again without supplying to the engine 1. Thereby, an intake pressure supplied to the engine 1 can be adjusted, the value of an exhaust gas rate and a NOx output can be controlled in a proper value, and the rise of a maximum pressure of combustion by the intake pressure up at the time of improving partial load performance can be simply suppressed. Furthermore, the compressed air bypassed is directly returned without passing the silencer, so that noises can be brought down, also loss of energy can be decreased.
