摘要： Disclosed herein is an exhaust insulator structure for a multi-cylinder engine of a vehicle. The structure includes an exhaust manifold, an exhaust gas purifier, and a heat insulator. The engine is able to switch its mode of operation from an all-cylinder operation in which all of four cylinders thereof are activated to a cylinder-cutoff operation in which two of the four cylinders are deactivated to serve as idle cylinders and the other two cylinders are activated to serve as active cylinders, or vice versa. The exhaust manifold includes: idle-cylinder-connected branched exhaust piping communicating with the idle cylinders; and active-cylinder-connected branched exhaust piping communicating with the active cylinders. A portion of the heat insulator facing the active-cylinder-connected branched exhaust piping has an opening that lets air blowing against the vehicle traveling into the heat insulator.

摘要： Provided is a powertrain for a vehicle in which an exhaust purifier is utilized as a dynamic damper. The powertrain includes an engine, and a transmission linked to the engine. The engine has an exhaust purification system containing a GPF device for purifying an exhaust gas. The exhaust purification system is disposed along a rear external surface of a cylinder head. The exhaust purification system is supported via a first support on the engine. A vertical side portion of the exhaust purification system is located downstream of the first support in a flow direction of an exhaust gas, extending in a direction away from the external surface.

摘要： An engine exhaust device includes: a first catalyst; a second catalyst; a connection member and an exhaust gas outlet pipe. The first catalyst has a downstream end face and the second catalyst has an upstream end face. The downstream end face and the upstream end face form a predetermined dihedral angle. The upstream end face of the second catalyst and a side surface of the first catalyst closely face each other to form an overlap. A center axis of the exhaust gas outlet pipe is offset further toward the first catalyst than a center axis of the second catalyst is.

摘要： An engine exhaust device includes: a first catalyst; a second catalyst; and a connecting member shaped into a tube and forming a part of the exhaust path, and connecting the first catalyst to the second catalyst. A downstream end surface of the first catalyst and an upstream end surface of the second catalyst form a dihedral angle within a range from 60 degrees to 120 degrees. A part of the upstream end surface of the second catalyst is close to and faces a part of a side surface of the first catalyst. On a cross-section including a central axis of the first catalyst and being parallel to a central axis of a second catalyst, a length of the part of the side surface of the first catalyst is longer than or equal to 10% and shorter than 50% of an entire length of the first catalyst.

摘要： In order to improve the performance of keeping the temperature of an exhaust purifier when a vehicle is running, an engine is provided with an exhaust passage behind a cylinder head in the vehicle longitudinal direction. The exhaust passage includes an exhaust manifold and an exhaust purification system disposed serially in a flow direction of an exhaust gas, the exhaust manifold being located upstream of the exhaust purification system. The exhaust purification system contains a GPF device configured to purify a gas. The exhaust purification system is located below the exhaust manifold, and is disposed so as to overlap the exhaust manifold in the vehicle transverse direction. The exhaust purification system is also disposed so as to protrude with respect to the exhaust manifold rearward in the vehicle longitudinal direction.
