Abstract: An engine is equipped with an engine body, a turbocharger, an exhaust gas purifier, an exhaust communication pipe. The turbocharger is connected to the engine body. The exhaust gas purifier purifies exhaust gas discharged from the turbocharger. The exhaust communication pipe connects the turbocharger with the exhaust gas purifier. The exhaust communication pipe includes: a first connection member that is connected to the turbocharger, and a second connection member that connects the first connection member with the exhaust gas purifier. A downstream end portion of the first connection member has an inner peripheral face having a cross-section of a circular shape. An upstream end portion of the first connection member has an inner peripheral face having a cross-section of an abnormal-shape that is different from the inner peripheral face of the downstream end portion.

Abstract: This diesel engine includes a turbocharger which compresses intake air by utilizing a flow of exhaust gas, and an exhaust gas after-treatment device which purifies the exhaust gas, wherein an exhaust pipe connects the exhaust gas after treatment device and the turbocharger, and is connected upwardly to the exhaust gas after-treatment device. The exhaust pipe can have a curbed portion, and have one end and another end, and both ends can face towards a front direction of the diesel engine. The exhaust pipe can be extended to a rear side in the engine front-rear direction, then bent by 180 degrees, and after being extended to a front side in the engine front-rear direction below the turbocharger, can be bent upward and is connected to the exhaust gas after-treatment device. The turbocharger can have an intake ejection pipe which ejects the gas and faces towards the front direction.

Abstract: An engine includes: two cylinder rows so placed as to be aligned side by side; a turbocharger; and an intercooler shared by the two cylinder rows, and connected to the turbocharger. The intercooler has: a cool liquid flow path through which a cool liquid flows, and an intake air flow path through which intake air from the turbocharger flows. The cool liquid flow path has an inlet and outlet of the cool liquid on one side in a first direction along the flow of the cool liquid. The intake air flow path has an inlet of the intake air on one side in a second direction along the flow of the intake air, and an outlet of the intake air on another side.
