Engine

An engine comprising an engine body (1), a DPF case (2), a high pressure EGR path (3), a supercharger (4) and a low pressure EGR path (5), in which the high pressure EGR path (3) is interposed between an exhaust manifold (6) and an intake manifold (7), an exhaust gas discharge path (8) extends from the DPF case (2), an intake pipe (9) extends from an air compressor (4a) of the supercharger (4), the low pressure EGR path (5) is interposed between the exhaust gas discharge path (8) of the DPF case (2) and the intake pipe (9), and the low pressure EGR path (5) is provided with a low pressure EGR cooler (10), wherein the DPF case (2) is installed in an engine body (1), and when an extending direction of a crankshaft (11) is defined as a longitudinal direction and a flywheel (12) is defined as existing on a rear side and a width direction of the engine body (1) is defined as a lateral direction, the low pressure EGR path (5) includes a rear path portion (13) extending along a rear side of the engine body (1), and a side path portion (14) extending along a lateral side of the engine body (1) on a side close to the exhaust manifold (6).
