Patent ID: 8235023

Claim:
An internal combustion engine comprising: a working cylinder with a working piston, a pre-ignition chamber with a spark plug, the pre-ignition chamber being shaped as a cup or a flattened cone, a diameter of the pre-ignition chamber's base being approximately equal to that of a cylindrically shaped combustion chamber; a fuel-air mixture injector, which is a compressor cylinder with a piston fuel, a delivery device and channels for supplying the fuel and air into the combustion chamber and channels for injecting of an fuel-air mixture into the combustion chamber; wherein a check valve is disposed between the fuel supply channel and the compressor cylinder, and wherein the engine has one or more pairs of channels for delivering the fuel-air mixture to the combustion chamber, axes of these channels are paired and angled towards each other at an angle between the axes of these channels and an axis of the combustion chamber, the angle being selected within an interval between a crossing point of the axes of those channels on a central electrode of the spark plug and the crossing point of the axis of the combustion chamber when a bottom of the working piston in its top dead point position.
