ABSTRACT:
A device for supplying air into the exhaust gases of an internal combustion engine to promote complete combustion of carbon monoxide and hydrocarbons for the reduction of atmospheric pollution has a manually operable shut-off valve held open by a spring, which can be operated by a push-button to intercept the supply of air to an air feed pipe when making test measurements on the engine or tuning the carburettor.
