Disclosed is a three cylinder engine wherein a vibration alleviation unit for alleviating vibrations in a vehicle when the engine is mounted in the vehicle is disposed either upon the crankshaft or upon a part that operates in unison with the crankshaft. The three cylinder is supported on the chassis by way of engine mounts that are positioned upon at least both ends of the engine in the direction of the crankshaft axis. Given that KV represents the spring constant of one of the engine mounts in the pitch direction of the crankshaft, KH represents the spring constant of the engine mount in the yaw direction of the crankshaft, MV represents the component of a primary couple that occurs in the three cylinder engine in the pitch direction, MH represents the component of the primary couple that occurs in the three cylinder engine in the yaw direction, and MVO represents the sum of MV and MH, then spring constants of the engine mounts are set such that KV > KH and the vibration alleviation unit is set so as to satisfy the condition 0 < MV/MV0 < 0.5.
