FIELD: engines and pumps.
SUBSTANCE: internal combustion engine with spark ignition is provided with a variable compression degree mechanism (A) capable of changing of mechanical compression degree, with a mechanism for adjustment of gas distribution of phases (B) capable of control of closing moment of an inlet valve and with a mechanism (23, 24, 25) EGR, supplying a part of waste gas through EGR-channel as EGR-gas to a combustion chamber. In internal combustion engine with spark ignition during engine operation at low load the degree of mechanical compression is higher as compared to that during engine operation at high load. The higher EGR part is, the higher the degree of actual compression is.
EFFECT: improving fuel flow.
