摘要： A hydrated EGR system, method and apparatus for a vehicle, in which heat from an exhaust pipe is used to heat an aqueous fluid solution in a water tank. A portion of the hot exhaust gas is diverted from the main exhaust flow, and the diverted portion is bubbled through the heated aqueous fluid solution to form a hydrated EGR mixture containing water vapor. The hydrated EGR mixture is then fed back to an intake portion of the engine, is mixed with an incoming fuel/air mixture, and is burned with the fuel air mixture inside the engine. The use of the hydrated EGR mixture, including heated water vapor, as part of the intake charge simultaneously reduces harmful exhaust emissions, improves engine performance, and improves fuel economy of the vehicle.

摘要： A buoyant component separator is disclosed for removing at least some floating contaminants from fluids. The component separator may be used with a marine engine exhaust system to reduce particulate matter and unburned fuel contained in liquid coolant before it is jettisoned overboard and pollutes the surrounding body of water. In one embodiment, the separator includes a first part for receiving a mixture of liquid and buoyant components and a second part joined by a communication passage, where the liquid flows through the communication passage to the second part and the buoyant components substantially accumulate in the first part. A method of separating a liquid from buoyant components is also provided.

摘要： In an engine exhaust muffler with an exhaust emission control function, the inside of a box-shaped muffler body is divided into a first exhaust chamber and a second exhaust chamber by a partitioning member which has a third exhaust chamber formed therein. The muffler body is provided with an exhaust inlet for introducing exhaust gas from an engine into the first exhaust chamber. The partitioning member is provided with first communication bores providing communication between the first and second exhaust chambers, and second communication bores providing communication between the second exhaust chamber and the third exhaust chamber. The third exhaust chamber is open to the atmosphere through an exhaust outlet pipe. An exhaust emission control catalyst is carried on an outer surface of the partitioning member facing the first and second exhaust chambers, as well as on an inner surface of the partitioning member facing the third exhaust chamber. An inner surface of the muffler body does not carry the exhaust emission control catalyst. Thus, in this exhaust muffler, thermal damages to the adjacent devices are less, the structure is simple and inexpensive, and a loss in output from the engine is less.

摘要： A two-stroke multiple cylinder engine includes a pair of exhaust chambers having a common control wall and each of which is connected between a corresponding plurality of selected cylinders and a common exhaust passageway. The connection between each of the chambers and the passageway is defined by a tuning section which is constructed of a sufficient length and configuration to generate a negative pressure pulse to aid scavenging and reflected positive pulses from the fired cylinder. In addition, the next fired cylinder of each group establishes super-charging of the engine. The common wall between the two tuned passageways is provided with a transfer port for transferring of a positive pressure signal from the one passageway into the opposite passageway which travels back toward the engine to provide a further positive super-charging pulse to the opposite exhaust chamber. The feedback pressure wave can be applied with particular advantage to four and two cylinder engines.

摘要： An exhaust apparatus for a small boat for reducing exhaust noise. A water muffler is provided at a midsection of the exhaust pipes extending from an engine which is provided in a boat body. An interior of the water muffler is partitioned into an expansion chamber and a resonator chamber with a front exhaust pipe connected to the engine and a rear exhaust pipe opening out of the boat being interlinked with the expansion chamber. The resonator chamber is directly connected to the midsection of the rear exhaust pipe via a connecting pipe. The water muffler is arranged in a longitudinal direction that is oriented in the fore-and-aft direction so as to extend along the side of a pump chamber in which a jet pump driven by the engine is arranged. A second resonator chamber is arranged along the water muffler on the outer side of the water muffler.

摘要： A muffler for muffling the exhaust sound of a motor boat having a diesel motor. The exhaust gases of the motor are led to a buffer chamber that is located beneath the waterline of the boat and mounted on a trim tab fitted to the transom of the boat. The bottom of the chamber is formed by the trim tab and includes a slot, which extends transversely to the direction of water flow. A flow casing through which exhaust gases exit into the water is provided beneath the slot.

摘要： An exhaust muffler for small marine craft that can be located in the rear portion of the bilge and straddle the drive shaft and the shaft log. The muffler has a shell formed from sides, ends, top and bottom walls. The bottom wall is provided with a concave depression to receive the shaft and shaft log. A preferred configuration of the depression is a semi-conical surface having a base proximate the inlet wall. Further, the top and bottom walls are configured to conform to the undersurface of the deck and the inside of the hull, respectively. An inlet pipe, or a multiple number of inlet pipes, receive exhaust gases and water from the exhaust manifold of the craft engine and direct this combination into the muffler above a water pool. Gases pass through the water pool and exit through an outlet pipe (or a plurality of outlet pipes). A downwardly extending conduit within the outlet pipe(s) provides a correct amount of lift such that an amount of water exits the muffler which is the same as the amount entering. Because of the shape and construction, this muffler can be placed within the bilge of the craft in a space that is normally waste.

摘要： A bubble silencer for use with scuba equipment is comprised of a flat flexible enclosure attached to a scuba regulator valve. Exhaust bubbles issuing from the regulator into the enclosure coalesce into large air parcels to be expelled at low velocity through a rearward exit port. The large size and low velocity of the exhaust bubbles leaving the enclosure are much quieter than the small high velocity bubbles issuing from the regulator itself.
