ABSTRACT:
Reactants having negligible activation energy react spontaneously and instantly upon contact to release heat. Such reactants are injected as colliding jets into a working fluid compressed in a combustion chamber of an internal combustion engine. The released heat causes the working fluid to expand against a movable member of the engine whereby mechanical energy is developed.
Preferred reactants having negligible activation energy are an alkali metal with water and a preferred working fluid is air. The combustion chamber reaction occurs in two distinct steps: In the first step, the alkali metal and water react with negligible activation energy to evolve hydrogen. In the second step, the evolved hydrogen and working fluid oxygen react with substantial activation energy. Undesirable effects of the activation energy are reduced by the substantial portion of heat release occurring in the first step and by improved ignition of the hydrogen as it evolves. Such reduced effects of activation energy allow improved engine design and operation to include optimal compression, simple and efficient open chamber engine structures, and assured self starting upon injection of said reactants into an engine stopped in an expansion phase.
