Document Type and Number:
WIPO Patent Application WO/1995/027846
Kind Code:
A1
Abstract:
An air-fuel ratio in each cylinder of an engine (11) is switched one after another from a stoichiometric mixture ratio to a lean air-fuel ratio at timing intervals, and an air bypass valve (43) is opened in parallel with this switching of the air-fuel ratio so as to gradually change an intake air quantity of the engine (11).
