An engine (1) has an exhaust manifold (12) provided with a communicating portion (25B) of a bypass line (25) from an air-supply side and a branch portion (31A) to an EGR line (31). When an exhaust gas outlet (13) is provided in an intermediary of the exhaust manifold (12) in a longitudinal direction

An engine (1) has an exhaust manifold (12) provided with a communicating portion (25B) of a bypass line (25) from an air-supply side and a branch portion (31A) to an EGR line (31). When an exhaust gas outlet (13) is provided in an intermediary of the exhaust manifold (12) in a longitudinal direction along an engine cylinder line, the communicating portion (25B) of the bypass line (25) and the branch portion (31A) of the EGR line (31) that are provided on the exhaust manifold (12) are provided on both sides in the longitudinal direction sandwiching the exhaust gas outlet (13) and spaced apart from each other so that a part of the exhaust gas is pushed by an air supply fed from the bypass line (25) is pushed to enter the EGR line (31).

The invention claimed is: 1. A supercharged engine with an EGR device, comprising:an exhaust manifold that collects exhaust gas discharged from respective cylinders to a single exhaust gas outlet;an intake manifold that distributes air supply from a turbocharger to the respective cylinders;an air-supply line from a compressor outlet of the turbocharger to the intake manifold;a bypass line that branches off the air-supply line at a position downstream of an after-cooler and intercommunicates the air-supply line and the exhaust manifold; andan EGR line that extracts a part of the exhaust gas from the exhaust manifold to return the part of the exhaust gas to the air-supply line;wherein the turbocharger comprises a compressor which is connected to the intake manifold, and a turbine which is connected to the exhaust manifold;wherein the bypass line communicates with the exhaust manifold at a communicating portion which is provided on one end of the exhaust manifold in a longitudinal direction along an engine-cylinder line; andwherein the EGR line branches from the exhaust manifold at a branch portion which is provided on another end of the exhaust manifold in the longitudinal direction.
