INTERNAL COMBUSTION ENGINE FOR DIESEL, GAS-DIESEL OR GAS MOTOR FUEL WITH SPARK IGNITION Russian patent published in 2019 - IPC F02B23/08 F02F3/26 

FIELD: motors and pumps.

SUBSTANCE: invention relates to internal combustion engines. Internal combustion engine for diesel, gas-diesel or gas motor fuel with spark ignition comprises one cylinder with piston in it, kinematically connected to crankshaft, cylinder head with installed in it inlet and outlet valves, combustion chamber on piston bottom, made in form of recess from rotation body, swirlers of charge in the form of end projections with tangential channels are located around combustion chamber on piston bottom and adjoin cylindrical recess in cylinder head and enter it at piston position in upper dead point, valves are located on grooves in cylinder head, depth of which corresponds to depth of cylinder head recess and height of end projections, wherein vortex charge movement at inlet into cylinder coincides in direction with direction of tangential channels on piston bottom, and ignition source installed in recess of cylinder head, at that engines for diesel, or gas-diesel, or gas motor fuel with spark ignition have unified head of cylinder with same depth of cylindrical recess in cylinder head, and depth of recess for valve corresponds to depth of head recess and height of end ledges on piston bottom, and unified aluminum pistons with same cylinder diameter on piston bottom for pressing inserts with end projections with interference, inserts have disk belt with outer diameter corresponding to piston diameter, and are made of high-alloy, corrosion-resistant and heat-resistant steel, for example, 10H18N9TL.

EFFECT: invention provides higher power, torque and reduced fuel consumption.
