An internal combustion engine having an exhaust system is shown provided with an air pump which is effective for supplying air to the exhaust system to oxidize unburned hydrocarbons within the exhaust gases of the exhaust system; a valve assembly, operatively interposed between the air pump and the exhaust system, is effective, in response to parameters of engine operation, to at times cause a portion or even all of the air supplied by the air pump to be delivered to the atmosphere instead of to the exhaust system.
The combination of an internal combustion engine having intake and exhaust manifolds, an air pump, means operatively connecting said air pump to said engine in order to drive said pump in relation to engine speed, conduit means for delivering air from said pump to said exhaust manifold, first means responsive to the attainment of a predetermined intake manifold vacuum during engine deceleration for preventing delivery of said air through said conduit means to said exhaust manifold during engine deceleration, second means including an opening to atmospher...
