ABSTRACT:
An engine system for a road vehicle includes an engine having an exhaust manifold which is coupled to an exhaust gas treatment device. A device is provided to deliver vaporized fuel or to burn fuel in the air inlet manifold to increase the level of noxious gas in the engine exhaust. In this case the treatment device is of the catalytic variety and the increase in the noxious gas content causes an increase in the temperature of the active mass of the treatment device resulting in self cleaning. For a non-catalytic treatment device a burner is disposed in the exhaust manifold.
