It is 5 times more efficient than conventional automobile internal combustion engines, and 3.5 times more efficient than hybrid automobile engines. It reduces auto emissions up to 90 percent, because the engine uses 60 percent of its fuel for propulsion, compared to a typical car engine that uses only 15 percent of fuel for propulsion. It does not have pistons, crankshafts, valves, or a transmission system, cooling system, emissions regulation or fluids reducing costs of the engine system 30% and maintenance costs. And, it can operate on natural gas, gasoline, hydrogen and other fuels.
