ABSTRACT:
A fuel combustion process is provided for a multi-cylinder engine for reducing exhaust emissions of carbon monoxide and unburned hydrocarbons. The process includes the steps of introducing hydrocarbon fuel in a first engine cylinder, burning the hydrocarbon fuel and producing exhaust gases, introducing the exhaust gases in a second cylinder, introducing hydrogen in the second cylinder, and burning the hydrogen with the exhaust gases, thereby producing exhaust emissions having a lower carbon monoxide and unburned hydrocarbon content than that of the exhaust gases produced in the first cylinder.
