Abstract
Pressurized and superheated, dry steam is admitted into the working chamber of a spark ignition engine for the purpose of increasing the thermal efficiency of the engine. The steam is admitted into the working chamber near the end of compression, and before ignition of the fuel. An igniter ignites the fuel. Additional work is pneumatically recovered from the steam, thus augmenting the total work obtained by the engine.
