FIELD: engines and pumps.
SUBSTANCE: three-cylinder engine comprises module to soften vibration in the vehicle. Three cylinders are supported by engine supports arranged at engine both sides along crankshaft axis. Provided KV and KH represent stiffness of the spring of one of engine supports in lengthwise direction and direction relative to crankshaft vertical axis, MV and MH are components of the first-order force pair components generated in three-cylinder engine in lengthwise direction and direction relative to crankshaft vertical axis while MV0 is the sum of MV and MH, then stiffness of the spring of one of engine supports is set so that KV>KH, and vibration dampening module is configured to satisfy the condition 0<MV/MV0<0.5.
EFFECT: decreased vibration.
