The present invention refers to a pneumatic engine with pistons similar to an inner combustion engine, where the fuel injection system as well as the use of spark plugs or any other element that generates a spark is replaced by an electrovalve device which controls the supply of air at pressure for operating the piston-connecting rod-shaft mechanism of the engine by means of compressed air. The air at pressure is generated by the use of compressors adjacent the engine and stored in tanks from where the engine is supplied by the electrovalve system. The electric power required for operating the engine, the compressors and the electrovalve system is obtained from a set of batteries (accumulators). The rotational movement at the front portion of the crankshaft is used for actuating the compressor. The motion of the crankshaft at the rear portion is used for operating an inertia steering wheel, or a torque converter, or a brake, or a force supply. The invention also has an ancillary syste m for starting the piston pneumatic engine which is mainly used in the start-up stage of the engine. Additionally, the engine includes a system for generating electricity from the wind energy that is obtained when the engine is used in a means for displacing it such as a car. The purpose of invention is to provide an ecological engine which may move a conventional vehicle of continuous use by means of compressed air, but without limiting the application thereof to the automotive sector. The pneumatic engine with pistons may be designed with different technical capacities and applications; the present document only describes the application of the invention in automotive vehicles but it is not limited thereto.
