Compressed air engine for vehicle propulsion - has central power cylinder with piston forming unit with compressor pistons

摘要

The engine has a central power cylinder forming a unit with air suction and compression pumps. The power cylinder piston forms a unit with the pump pistons. The pistons can be of the free type, and the power piston can have a protrusion shutting off the fuel inlet at the appropriate moment. The sparking plugs can be mounted on the piston itself, on the protrusion, which also has a contact working with one inside the fuel inlet to give ignition at the appropriate moment. The design can also be such that the ignited fuel never has the chance to escape completely, thus giving more complete combustion.
