Control apparatus for deposit removal in internal combustion engine, has deposit removal execution section which controls adjustable valve mechanisms in raising flow velocity into cylinder and performs deposit removal operation

摘要

A deposit removal execution section controls the adjustable valve mechanisms (424,434) in raising the flow velocity into a cylinder and performs deposit removal operation. The increase of the flow velocity of the intake in an internal combustion engine (100) removes the deposit adhering to the inlet valve (422) area.
