The invention "An Internal-Combustion engine" refers to a turbo-compressor with a direct fuel-injection in the cylinders (2) which are double-sided covered by cylinder heads (4, 5). Referring to the petrol variant of the engine, the injection of the fuel is accomplished by low-pressure injection system using injection nozzles (26) which are mounted in the cylinders' walls, and the combustion of the air-fuel mixture is done traditionally by ignition plugs (24), mounted in the cylinder heads. Referring to the diesel variant of the engine the injection of the high-pressure fuel from the fuel-injection pump is accomplished using the traditional way of fuel-injection nozzle in the heads of the cylinders (2). The gas distribution in the one-stroke turbo-compressor engine is realized by the heads of hollow double-stroke pistons (27) on which are mounted central hollow piston rods (29) on the bottom piston heads and tube-like air-conductors on the top piston heads (4). Both have orifices (38) in their walls which are situated at such a distance from the piston heads which is equal to the piston travel. The air, fed from the turbo-compressor (10) by a delivery line, flows within the pressurized space covered by a joint for all top heads hood blows down through the orifices in the walls of the air-conductors into the top half-part of the cylinders when the pistons reach bottom dead centre. The air passes through and cools from inside the double-stroke hollow pistons (27) and then through the orifices of the piston rods the air flows and scavenges the bottom half-parts of the cylinders when the pistons reach top dead centre. In the pistons are installed hollow thin-walled bodies in order to improve the cooling of the piston walls and heads. The piston rods (26) are connected on the opposite end to crossheads (37) which are connected to pitmans hubs of the crankshaft mechanism. The crossheads (37) move like pistons (27) in cylinders in the engines body which are coaxial with the engine cylinders (2).
