ターボ過給機付エンジンの制御装置

Japanese Patent JP4250824

B2

PROBLEM TO BE SOLVED: To prevent becoming lean of an air-fuel ratio and the increase in the generation of NOx by correcting an inclination for an exhaust reflux amount to temporarily decrease during deceleration, in an engine with a turbosupercharger. SOLUTION: This device comprise a variable blade to change an area of a flow of exhaust gas to the turbine of a turbosupercvharger; an EGR device having an EGR valve; a fuel injection valve, and a control unit to control the above device. This control unit comprises an operation state detecting means 48; a control means 40 to control the variable vane and the EGR valve according to an operation state detected by the operation state detecting means 48. The control means 40 at least partially opens the EGR valve during deceleration of an engine from a state in which supercharge and reflux of exhaust gas are carried out, and the variable blade is controlled such that an area of a flow of exhaust gas to a turbine is temporarily decreased and this constitution increases an exhaust pressure in a spot situated stream from a turbine and promotes EGR.
