FIELD: engines and pumps.
SUBSTANCE: internal combustion engine (ICE) includes cylinders, fuel spray injectors (11-18) and at least two common high pressure fuel lines (R1, R2). Cylinders are grouped at least in two rows (B1, B2). Injectors (11-18) of one row (B1, B2) of cylinders are connected to different common high pressure fuel lines (R1, R2). Also, ICE version with cylinders grouped at least in two rows (B1, B2) in which each atomiser is connected to one of common fuel lines (R1, R2) is described. Each common fuel line (R1, R2) has its own high pressure pump and common fuel lines (R1, R2) are hydraulically connected to each other. Besides, there described is operation control method of ICE with several cylinders, the common fuel lines (R1, R2) of which are hydraulically connected to each other, at which fuel pressure in one common fuel line (R2) is controlled, and pressure is controlled in advance in the other common fuel line (R1).
EFFECT: reduction of pressure fluctuations in common high pressure fuel lines.
