FIELD: engines and pumps.
SUBSTANCE: four stroke ICE comprises at least two cylinders 1, piston 7, mechanism to convert reciprocation of pistons into engine crankshaft rotation, turbo compressor 14, shut-off nozzle 5, injector 4 to feed hydrocarbon fuel, vortex tube 17, tank 18 for water or water-alcohol solution of ammonium nitrate. Mechanism to convert reciprocation of pistons into engine crankshaft rotation comprises con rods 10, disks 9, connecting shaft 11 and shaft of engine 8. Disks 9 are provided with two grooves 12 to accommodate slide 13. Con rods 9 are articulated with slides of appropriate disks 13. Turbo compressor 14 is coupled with inlet and discharge manifolds 14 and 15, respectively. Fuel mix contains water or water-alcohol mix of ammonium nitrate. Shut-off nozzle 5 serves to feed water or water-alcohol mix of ammonium nitrate. "Hot" outlet of vortex tube 17 is communicated with heating system of tank 18. "Cold" outlet of vortex tube 17 is communicated with liquid cooling system.
EFFECT: reduced probability of detonation, decreased harmful emissions and fuel consumption.
