The flange assembly includes a first flange having a first mating face and a second flange connected to the first flange, wherein the second flange has a second mating face. A sealing structure is formed with the mating faces of the first and second flanges, wherein the sealing structure comprises a groove positioned on the first mating face and a ridge positioned in the second mating face, wherein the ridge occupies at least a portion of the groove with the first flange connected to the second flange.

An exhaust gas purification device having such a structure that exhaust gas can uniformly flow into without depending on a shape of an exhaust gas inlet pipe. A gas purification body which purifies the exhaust gas, a purification casing which accommodates the gas purification body, an exhaust gas inlet pipe which communicates with an exhaust gas inflow port of the purification casing, and an exhaust gas outlet pipe which communicates with an exhaust gas outflow port of the purification casing. The exhaust gas inlet pipe is attached to the purification casing in such a manner as to cover the exhaust gas inflow port and extend in a longitudinal direction of the purification casing. An introduction passage of the exhaust gas is formed by an outside surface of the purification casing and an inside surface of a pipe wall of the exhaust gas inlet pipe. A portion extending along the purification casing in the pipe wall is inclined so as to come close to the outside surface of the purification casing in proportion to heading for an exhaust gas outlet side from an exhaust gas inlet side.

An exhaust heat recovery device includes: a first pipe through which exhaust gas from an engine flows; a second pipe that communicates with the first pipe and bypasses the first pipe; a heat recovery unit that is disposed at an interior of the second pipe, and that exchanges heat between the exhaust gas and cooling water that circulates at an interior of the heat recovery unit, and that recovers heat of the exhaust gas; and a heat transfer suppressing mechanism that is provided at a portion connecting the first pipe with the second pipe, and that suppresses transfer of heat from the first pipe to the second pipe.

A bulldozer according to the present application includes a main frame, and an engine, a hood and an exhaust after-treatment device are provided on the main frame, an air inlet of the exhaust after-treatment device is in communication with an air outlet of a turbine of the engine via a pipeline, and the exhaust after-treatment device is fixed to the hood. In the bulldozer, vibration generated by the engine is transmitted to the main frame through an engine supporting frame or a damping device, and then transmitted from the main frame to the hood, the transmission path of the vibration is long, thus the vibration damping becomes complicated and has a high damping value, and the vibration transmitted to the air cleaner is really small.

An exhaust system is disclosed for a use with an engine. The exhaust system may have a plurality of manifold sections, each being connected to an adjacent one of the plurality of manifold sections and thereby forming an exhaust manifold. The exhaust system may also have a plurality of elbow-shaped coolant adapters, each being configured to connect a corresponding one of the plurality of manifold sections to a corresponding cylinder head of the engine and having a coolant jacket formed therein. The exhaust system may further have a heat shield formed around the exhaust manifold.

A heat shield for shielding of hot areas of a combustion engine. The heat shield has at least one metal sheet layer with a first and a second surface. The at least one metal sheet layer has at least one passage opening for the passage of a fastening element. The layer also has a sleeve which passes through the passage opening. The heat shield further has a decoupling element from flexible material arranged between a circumferential edge of the passage opening and the sleeve. The decoupling element and the sleeve each have a) an annular shank area, which penetrates the passage opening, b) a first collar, which on the first surface extends radially outward relative to the circumferential edge of the passage opening, and c) a second collar, which extends adjacent to the second surface radially outward relative to the circumferential edge of the passage opening.

A connector system for attaching diffusers to automotive vehicle exhaust systems which, in accordance with the characteristics thereof, provides a connector system in a specific structure of the mechanical type and based in an outlet nozzle with a groove flange, a tongue flange making the interface outlet nozzle-diffuser, an outlet connector with a tongue flange making the interface to the automotive vehicle exhaust system, a groove flange making the interface outlet connector-diffuser, and fixing clamps for the pairs of tongue-groove flanges, in order to provide complete optimization procedures to press fit and fasten the diffusers and their parts such as outlet nozzles and outlet connectors to automotive sports vehicle exhaust systems, coupled with a 360-degree double rotating system of their parts.

An object in mounting an engine on an exhaust gas purifier is to ensure the coupling strength between the engine and a hanger and to balance the whole engine at the time of lifting while avoiding interference between the exhaust gas purifier and the hanger. An engine apparatus includes an exhaust gas purifier configured to purify exhaust gas from the engine. The exhaust gas purifier is mounted on the engine through a mounting base. A lower end of the hanger, which is configured to lift the engine, is fastened to the mounting base. An upper end of the hanger is extended along an outer periphery of the exhaust gas purifier.
