Abstract
An exhaust system device (1) for a vehicle (100) comprises an exhaust purification device (18) and a first exhaust gas recirculation (EGR) cooler (24). The exhaust purification device (18) is disposed with a central axis of a downstream-side end inclined downwardly toward a rear side of the vehicle (100). The EGR cooler (24) is provided so as to introduce exhaust from a downstream side of the exhaust purification device (18), is adjacent to the exhaust purification device (18) and fixed to the exhaust purification device (18), and is disposed such that a central axis of the EGR cooler (24) is inclined downwardly toward the rear side of the vehicle.
Claims15
An exhaust system device for a vehicle comprising:
- an exhaust purifier;
- and
- an exhaust gas recirculation (EGR) cooler,
- wherein
- the exhaust purifier is disposed with a central axis of a downstream-side end inclined downwardly toward a rear side of the vehicle,
- the EGR cooler is provided so as to introduce exhaust from a downstream side of the exhaust purifier to an intake passage provided on a side of an engine opposite to a side of the engine on which the exhaust purifier s provided, is adjacent to the exhaust purifier and fixed to the exhaust purifier, and is disposed such that a central axis of the EGR cooler is inclined downwardly toward the rear side of the vehicle, and
- the EGR cooler is adjacent to the exhaust purifier on one side of the engine in the vehicle-width direction, and a pipe connecting the EGR cooler and the intake passage extends along a side surface of the engine on the one side of the engine in the vehicle-width direction, and is connected to the intake passage on the one side of the engine in the vehicle-width direction and on the side of the engine opposite to the side of the engine where the exhaust purifier of the engine is provided.
An exhaust system device for a vehicle, comprising:
- an exhaust purifier;
- and
- an exhaust gas recirculation (EGR) cooler,
- wherein
- the exhaust purifier s disposed with a central axis of a downstream side end inclined downwardly toward a rear side of the vehicle,
- the EGR cooler k provided so as to introduce exhaust from a downstream side of the exhaust purifier, is adjacent to the exhaust purifier and fixed to the exhaust purifier, and is disposed such that a central axis of the EGR cooler is inclined downwardly toward the rear side of the vehicle,
