Abstract (en)
The two-stroke twin-injector-per-cylinder engine is characterized by the introduction of a compressed-air supplementary injector which enables the engine to operate as a two-stroke only engine and with the exhaust valves alone. This simplification makes it possible to achieve a higher power compared to the traditional four-stroke engine. The engine must be provided with a compressor-tank assembly combined with one or more turbosuperchargers in series with air intake and choke tube, a computerized electronic control unit and an injection fuel pump and electro-injection valves with different characteristics between Diesel engines and petrol engines. The materials, pressures, dimensions and electric wiring schemes adopted are appropriate for any type of vehicle and for the aforesaid purpose. The introduction of the compressed-air injector guarantees an increase in volumetric efficiency and in power of any type of internal combustion engine provided with compressor, with or without tank, or even only with a turbosupercharger or turbo-intercooler. <IMAGE>
