Valdespino, J M

An improvement in internal combustion engines is described characterized by: an internal combustion engine having fuel feed means for feeding a hydrocarbon fuel-air mixture to at least one combustion chamber; ammonia storage means for storing ammonia in proximity to the internal combustion engine; ammonia feed means for feeding ammonia from the ammonia storage means to the internal combustion engine combustion chamber with the fuel-air mixture charge; means coupled to the ammonia feed means between the ammonia storage means and the internal combustion engine for dissociating the ammonia into hydrogen and nitrogen and feeding the gas to the engine with the hydrocarbon fuel-air mixture, whereby ammonia is fed into a combustion chamber substantially dissociated; feed control valve means connected to the ammonia feed means; means to lean the hydrocarbon fuel-air mixture of the internal combustion engine below the normal hydrocarbon fuel-air operating range when ammonia is being dissociated and fed from the ammonia storage means by the ammonia feed means to the internal combustion engine; and means to switch the internal combustion engine back to a normal hydrocarbon fuel-air mixture.
