Abstract
Abstract A smog-free automobile is described burning fuel and substantially pure oxygen and spray water cooling the cylinder walls and pistons during exhaust. A dual combustion system is utilized, Otto cycle for cruise power and diesel cycle above cruise power, and water is recovered from the exhaust. The fuel can be pure hydrogen or liquid gasoline. With liquid gasoline, oxygen input atomizes the gasoline and with hydrogen fuel both hydrogen and oxygen can be produced by electrolysis, ideally utilizing nuclear electric generation for a complete smog-free system operation. Gaseous material is stored in a plurality of high-pressure vessels and in the case of hydrogen fuel with the pressure vessels at the rear of the auto. Separate sets of vessels are provided for cruise power supply and above cruise power supply and valving is provided to use the opposite set of tanks in case fuel for one operation is exhausted.
