FIELD: engines and pumps.SUBSTANCE: invention can be used in engines with direct fuel injection into combustion chamber. In engine, comprising a cylinder, a piston and a cylinder head with an inlet valve, forming a combustion chamber, cylinder head has a guiding device. Guiding device has radial-tangential channels and is located so that air supplied to combustion chamber through inlet valve passes through channels is swirled and forms a vortex. Device for supply of fuel is at a distance from cylinder axis and fuel injection is performed in a vortex area with higher peripheral speed.EFFECT: invention improves mixing fuel with air, improves combustion efficiency and provides smooth combustion.3 cl, 4 dwg |
