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.
