Abstract
The invention discloses a pressure range liquid cooled engine which comprises a cylinder piston mechanism. A gasoline fuel nozzle is arranged on the cylinder piston mechanism or a gas inlet of the cylinder piston mechanism. A liquid nozzle is arranged on the cylinder piston mechanism and is controlled by a pressure range jet control device. The pressure range liquid cooled engine can reduce gas temperature at the beginning time of a compression stroke of a cylinder piston type engine, and enables fuel to release heat on the conditions that temperature is low and pressure is high, so that production of pollutants such as nitrides are reduced. Consequently, emission of the pollutants is reduced. Meanwhile, the efficiency of the cylinder piston type engine can be improved. Especially, the efficiency of engines using gasoline as fuel can be greatly improved.
