FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: according to proposed method of compression and ignition of fuel mixture in two-piston engine with one combustion chamber, compression is built by first and second pistons, with first piston moving with lead relative to second piston, as angles of cranks are within 0.1° and 90° between their planes of rotation and ignition of compressed fuel mixture is provided at definite moment of time. Method is aimed at providing minimum consumption of fuel per power unit of engine owing to the fact that maximum compression is built in one combustion chamber at definite moment of time when crank relating to second piston is within 90° - 0.1° relative to its top point not reaching the top point, and crank relating to first piston is from 30° relative to its top point before top point and to 60° relative to its top point, after its top point, and compressed mixture is ignited at definite moment of time. Said time moment is calculated from creating of 80% of maximum compression with increasing to maximum value and decreasing to 90% of maximum value.
EFFECT: reduced fuel consumption per engine power unit.
