An engine includes an engine body, a DPF case therein, high pressure and low pressure EGR paths, and a supercharger. The high pressure EGR path is between exhaust and intake manifolds. An exhaust gas discharge path extends from the DPF case. An intake pipe extends from the supercharger air compressor. The low pressure EGR path is between the exhaust gas discharge path of the DPF case and the intake pipe. The low pressure EGR path includes a low pressure EGR cooler. An extending direction of a crankshaft defines a longitudinal direction. A flywheel exists on a rear side. A width direction of the engine body defines a lateral direction. The low pressure EGR path includes a rear path portion extending along a rear side of the engine body, and a side path portion extending along a lateral side of the engine body on a side close to the exhaust manifold.
