초록

Compressor surge on turbocharged Diesel engines when operating in temporary throttled airflow, such as are required for the periodic regeneration of lean NOx traps is prevented by controlled operation of a boost air blow-off valve positioned downstream of the compressor outlet of the turbocharger.

대표
청구항

What we claimed is: 1. A method for controlling boost pressure to prevent compressor surge in a turbocharged Diesel engine during temporary operation in one of a stoichiometric or richer combustion mode, comprising: defining the surge limits of a compressor of said turbocharger; reducing the flow of intake air during said temporary operation in one of a stoichiometric or richer combustion mode to provide exhaust gases that are substantially free of excess oxygen; determining the intake air pressure ratio between an inlet and an outlet of said compressor...
