ABSTRACT:
A late injection direct injection stratified charge spark ignition engine is provided with a catalytic grid disposed in the path of injected fuel spray and downstream of the point of spark ignition to assist the completion of combustion of previously ignited fuel spray as well as to ignite and cause the combustion of previously unignited fuel elements passing therethrough. Improved combustion and reduced hydrocarbons emissions are anticipated.
