ABSTRACT:
Conventional reactants, such as hydrocarbons or hydrogen with air, which are used by most internal combustion engines have substantial activation energies which limit conditions under which the engines will start and operate. In a typical starting process, a separate starter motor turns the engine through several full cycles so that a compressed mixture of the reactants will ignite.
The invention includes reactants which have negligible activation energy, such as an alkali metal with water, and thus react upon contact to evolve a hot gas. An internal combustion engine is stopped in an expansion phase where it may remain for a time which is sufficient to approach equilibrium at ambient temperature and pressure in a combustion chamber. Starting comprises injecting the reactants in a contacting relationship into the combustion chamber which is stopped in an expansion phase whereby ignition must occur to rapidly evolve the hot gas and force the engine to advance. As the engine advances into phases of normal operation, the reactants having negligible activation energy are injected into a working fluid at optimal compression for efficient conversion to mechanical energy which is transmitted to a load.
The invention provides an assured starting transition to normal operation with simple apparatus and a low input of energy. The engine may stop whenever the accelerator is released for fuel economy during idling with assured restarting on demand.
