A diameter of the outer opening is less than a diameter of the inner opening. A thickness of the second inwardly extending part is less than the diameter of the outer opening.

Exhaust gas processing device

In an exhaust gas processing device, an air-fuel ratio sensor is provided such that a measuring portion is located in a region surrounded by a downstream-side end surface of a TWC, an upstream-side end surface of a GPF, and an inner wall surface of a case against which the exhaust gas G that has passed through the TWC flows, that is the region a region on the GPF side of the center of the TWC.

Turbocharged engine arrangement

An engine is provided with an engine body, a crankshaft, a cooling fan, an exhaust manifold, a supercharger, an ATD that purifies exhaust gas, and a second exhaust pipe. When the height direction of the engine is defined as a first direction, the crankshaft extends in a second direction vertical to the first direction. The cooling fan is disposed on one side of the engine body in the second direction. The supercharger is driven by the exhaust gas from the exhaust manifold. The second exhaust pipe connects the supercharger and the ATD. The ATD is disposed in an attitude in which the longitudinal direction thereof is parallel to the second direction. The second exhaust pipe is connected to the cooling fan side of the ATD in the second direction. The second exhaust pipe is disposed so as to pass laterally with respect to the exhaust manifold and below the supercharger.

In-Port Ship Exhaust Capture Device
20230234692 · 2023-07-27 · ·

A device for capturing in-port ship exhaust gases is designed to be connected to a ship, when the ship has at least one funnel that serves as an outlet for exhaust gases. The device includes at least one collection device, including a hood designed to connect to the funnel at the exhaust outlet so as to collect the exhaust gases coming out of the funnel, a handling unit designed to move the collection device and position it at the exhaust outlet, a first constraint configured to interconnect or disconnect the collection device and the handling unit by command so as to create a handling configuration in which the collection device and the handling unit are interconnected by the first constraint and can be moved as one, and a collection configuration in which the collection device collects the exhaust gases and the connection achieved by the first constraint is released, and a second constraint configured to exert a magnetic attraction force, by command, intended to put the first constraint into the handling configuration.

Exhaust lining having a connecting element
11566556 · 2023-01-31 · ·

An exhaust lining for an exhaust system of a motor vehicle has a first connecting element clamped between a first and second pipe. The first pipe forms a tailpipe. The second pipe forms a tailpipe cover. The tailpipe cover has a tubular inner part held on by means of the first connecting element which clings onto the first pipe via by means of a lever mechanism. A load arm of the lever mechanism, having the distance A, is shorter than an effort arm, having the distance B. The length of the effort arm is precisely defined, because the end of the effort arm lies against the first pipe via a punctiform contact area. A first contact surface of a clamping spring is designed offset from the longitudinal extent of a main body of the first connecting element to save space in the longitudinal direction of the main body.

Exhaust muffler structure

An exhaust muffler structure to which an exhaust pipe for guiding exhaust gas from an engine to an exhaust muffler is connected, the exhaust muffler structure comprising a catalyst device, included inside the exhaust muffler structure, having a catalyst for purifying the exhaust gas of the engine, wherein the catalyst device has one end connected to the exhaust pipe and is supported inside the exhaust muffler via the exhaust pipe, and a body portion of the catalyst device is supported by a first partition wall having an inner partition wall and an outer partition wall that is on the outer side of the inner partition wall, and the outer partition wall is fixed to the inner wall of the exhaust muffler, and the inner partition wall is fixed to the outer wall of the catalyst device.

Joint assembly, v-clamp, and end flanges

A v-clamp provides an enhanced axial load to tubular body end flanges in order to establish a fluid-tight joint therebetween. The v-clamp, according to an example, has a v-angle that varies in value over a section or more of a band of the v-clamp. The varying v-angle has been shown to effect an axial load that is more evenly and uniformly applied around a circumference of the v-clamp and to the underlying tubular body end flanges. Furthermore, in an example, the tubular body end flanges have a partially spherical shape.

Method and apparatus for converting a vehicle from a dual-in, single-out exhaust system to a dual-in, dual-out exhaust system
11713700 · 2023-08-01 ·

An exhaust pulse balance chamber comprising a circular collar, mid-section that bulges at its center, skirt, and right and left legs, all of which are sealed to the exterior environment and in fluid communication with one another. The outer diameter of the skirt increases in width but not in depth from the proximal end of the skirt to the distal end of the skirt, which is configured to receive the right and left legs. Each leg is bent at a 30-degree angle relative to the central longitudinal axis of the exhaust pulse balance chamber. The invention includes a method of using the exhaust pulse balance chamber to convert a vehicle from a dual-in, single-out exhaust system to a dual-in, dual-out exhaust system.
