Abstract
Abstract An ozone production system for use with hydrocarbon fuel apparatus, such as internal combustion engines, to improve the efficiency of combustion and to limit ozone emissions in the exhaust. The system comprises electrode means for the production of ozone arranged in association with the air inlet of an hydrocarbon fuel apparatus, an ozone sensing means associated with the exhaust outlet of the hydrocarbon fuel apparatus, and control means operative in response to an output of the ozone sensing means for supplying electricity to the electrode means for producing ozone at a controlled rate so as to limit the ozone emissions at the exhaust outlet and so as to supply sufficient ozone for complete combustion of the hydrocarbon fuel.
