A lean mixture, rich in hydrogen, is introduced into the combustion chamber. Fuel is then injected to the center of the chamber to provide a rich strata. The rapid flame front propagation due to the hydrogen minimizes the HC production quench.

Internal combustion engine operated on injected fuel supplemented with

To a mixture of hydrogen and oxygen or air having the stoichiometric oxygen-to-hydrogen ratio, a diluent gas such as carbon dioxide or argon is added before the mixture is fed to the combustor when the burning rate of the mixture is excessively high. The diluent in the combustion gas can be reused after separation of water.
