Connor, M J

This patent describes a system for improving the efficiency of an internal combustion engine having at least one combustion chamber, an air intake manifold and an operator controlled throttle. It comprises: at least one electronically actuated fuel injector; a fuel supply reservoir communicatively connected with the fuel injector and including fuel pumping means for maintaining constant fuel pressure at the inlet of the fuel injector; at least one electronically actuated water injector; a water supply reservoir communicatively connected with the water injector and including water pumping means; an air flow measuring means for determining the rate of air flow through the air intake manifold; means for measuring power demand operatively associated with the throttle; and regulating means for controlling the rate at which atomized fuel and water are independently injected into the combustion fuel mixture of the engine.
