A sensor apparatus for examining a sample gas volume, particularly for capturing the particulate matter content of a sample gas volume, includes at least one measuring chamber to accommodate the sample gas that is to be analysed, and at least one sample gas feed allocated to the measuring chamber and with at least one sample gas discharge allocated to the measuring chamber, in which it is provided as essential for the invention that at least one cleaning gas feed is allocated to the measuring chamber, that the cleaning gas feed is connected to the measuring chamber via at least one cleaning gas inlet, that a condensation area is allocated to the cleaning gas feed, and that the condensation area is arranged in front of the cleaning gas inlet of the cleaning gas feed into the measuring chamber.

Disclosed is an exhaust system for a vehicle having an exhaust passageway through which products of combustion from the engine pass through and out to atmosphere, which exhaust system has a bead portion formed in the exhaust passageway with one more holes in the lower portion thereof through which at least a portion of the rain which has entered the interior of the exhaust passageway may flow out from the interior of the exhaust passageway prior to flowing downward to a lower portion of the exhaust passageway at which the rain is undesirable.

A muffler with ease discharge of condensate may include a housing formed of a cylinder shape and provided with an end plate at both end portions thereof, at least one baffle disposed in the housing to divide the internal space of housing into a plurality of chambers, an inlet pipe introducing exhaust gas in the housing, an outlet pipe discharging the exhaust gas from the housing the outside, so that the exhaust gas flowed into the inlet pipe flows through the chamber divided in the housing to be discharged through the outlet pipe, a condensate collecting tube disposed along the lower surface of the housing and provided with a passage in which the condensate gathered in the lower surface of the housing is introduced to be flowed and a condensate inducing tube connecting the condensate collecting tube and the outlet pipe.

An exhaust aftertreatment system includes a first catalytic converter, an oxidation catalyst including a storage catalyst, an air injector, and a cooling unit. The exhaust aftertreatment system is fluidly coupled to an output of a spark-ignited internal combustion engine that operates in the rich regime during acceleration and the lean regime during deceleration. In one aspect, the storage catalyst stores ammonia produced while the engine operates in the rich regime. The stored ammonia reacts with nitrogen oxide compounds produced when the engine operates in the lean regime. In another aspect, the nitrogen oxide compounds react with ammonia produced while the engine operates in the rich regime.

An exhaust aftertreatment system includes a first stage catalytic converter, a second stage catalytic converter, and a conduit extending from the first stage catalytic converter to the second stage catalytic converter. The conduit passes through an exhaust gas intercooler, between the first and second stage catalytic converts, that reduces the temperature of the exhaust to about 300 F. to about 500 F. Air is ejected into the exhaust conduit to increase the oxygen concentration in the exhaust before it passes through the second stage catalytic converter. The air can be ejected from an air ejection conduit that extends to an engine charger compressor or a compressed air conduit that extends from the engine charger compressor, such as a turbo charger and/or a supercharger, to the engine. A gas particulate filter can be disposed in the exhaust conduit or it can be integrated with the second stage catalytic converter, for example as a catalyzed gas particulate filter.

A bottoming cycle power system includes an expander disposed on a crankshaft. The expander being operable to receive a flow of exhaust gas from a combustion process and to rotate the crankshaft as the exhaust gas passes through. An absorption chiller system has a generator section having a first heat exchanger to receive the flow of exhaust gas from the expander and to remove heat from the exhaust gas after the exhaust gas has passed through the expander. An evaporator section has a second heat exchanger to receive the flow of exhaust gas from the generator section and to remove heat from the exhaust gas after the exhaust gas has passed through the generator section. A compressor is disposed on the crankshaft and connected to the flow of exhaust gas. The compressor is operable to compress the exhaust gas after the exhaust gas has passed through the second heat exchanger.

A water separator for use in a marine exhaust system comprises a horizontally disposed, generally cylindrical housing including a wet exhaust inlet, a dry exhaust outlet, and a water outlet. Wet exhaust entering the wet exhaust inlet is constrained against the inner housing wall by a variable geometry vane or baffle which causes the wet exhaust to accelerate such that centrifugal force causes the entrained water to separate from the exhaust gas. Separated water encounters a longitudinally disposed barrier and flows to the water outlet for discharge from the vessel. A tubular dry exhaust pipe is longitudinally disposed within the housing and includes an inlet disposed in proximity to a first end thereof, and an outlet projecting from a second end thereof.

The present invention relates to use of a lubrication oil that forms water-soluble ash when combusted in an engine system, where the engine system comprises an internal combustion engine; an exhaust gas system comprising a diesel particulate filter to capture particulate matter from the exhaust gases, including the water-soluble ash; and an exhaust gas conduit to lead exhaust gases from the internal combustion engine to the exhaust gas system, and to collect condensed water formed by a cold start and/or a cold operation of the internal combustion engine and lead the condensed water through the diesel particulate filter, thereby dissolving and removing the water-soluble ash from the diesel particulate filter.

In an exhaust system of an internal combustion engine, an exhaust pipe is reliably bent and deformed during vehicle rear collision while improving drainage performance in the exhaust pipe in normal times. The exhaust system 1 includes a second pipe 17 corresponding to a downstream end part of an exhaust pipe 10 through which exhaust gas flows from an engine 2. The second pipe 17 includes: a fragile part 30 as a starting point of bending deformation of a tail pipe 13; and a partition plate 20 vertically dividing the inside of the second pipe 17 to form, under the partition plate 20, a lower passage 7 to flow water that accumulates in the exhaust pipe 10. The partition plate 20 is in a vicinity of the fragile part 30 and at a position not overlapping with the fragile part 30 in an axial direction of the second pipe 17.

A fluid cleaning and filtering system includes a pre-treatment system before a force generation turbine to condense and pretreat gases and particulate matter; a flow rectifier before a tangential inlet; diffuser pipes for compressing the gases and particulate matter therein and project same into the deflector disks, diffuser pipes at an outlet of the so-called condenser, a purger, a diffuser and a deflector; a force generation turbine; an energy generator using torque from the turbine rotor; an internal energy generator; a flow rectifier in a first tangential inlet and a flow rectifier in a second tangential inlet; a new full-cone atomizer nozzle to wet particles and clean gases; a diffuser in the condensers and a deflector disk for the condensers.
