The concept of an internal combustion engine where the oxidation of the fuel is brought about with the aid of a catalyst offers the advantages of a stratified charge engine without the disadvantages. It should give good economy and low emissions of exhaust pollutants. Several such catalytic engines have been built and run, and test results are promising; in particular, one engine shows better fuel economy than the conventional petrol engine coupled with lower hydrocarbon emissions than either petrol or diesel engines.
