Abstract: A valve assembly defines a chamber and three ports. A first valve selectively obstructs a first port to prevent fluid communication between a secondary air injection pump and the chamber. A second valve selectively obstructs a second port to prevent fluid communication between an air intake manifold and the chamber. A third port provides fluid communication between the chamber and an exhaust manifold. The chamber thus serves as a common passageway for secondary air flowing from the pump to the exhaust manifold and for exhaust gas flowing from the exhaust manifold to the air intake manifold. In a preferred embodiment, the first and second valves are rigidly interconnected.

The exhaust passage (25) is formed in the center of the exhaust system provided with the exhaust emission control unit. By-pass passages (26) are formed at both sides of the exhaust passage (25) through which the exhaust gas flows without passing through the exhaust emission control unit. The exhaust heat collecting unit (29) is provided on the outer side of each of the by-pass passages (26).

A desulfurization process can be initiated when the NOx value is less than or equal to a first selected value. During the desulfurization process, when the third oxygen sensor signals a condition rich of stoichiometry, oxygen can be provided to the catalyst.

Abstract: An emissions control system utilizes otherwise wasted heat to efficiently reduce emissions in a main exhaust flow. Heat stored in exhaust from an auxiliary generator (i.e., auxiliary exhaust) may be used to convert urea to ammonia used by a Selective Catalytic Reducer (SCR) system, and/or the auxiliary exhaust may be used to heat the main exhaust flow before entry into an SCR. Additionally, a heat exchanger may be used to transfer heat from a hot clean flow out of the SCR, to the main exhaust flow entering the SCR. Previously, mobile emissions control systems have not used SCR systems to reduce NOx because of the cost and space required for heater fuel. The efficient use of otherwise wasted heat reduces fuel cost and fuel storage requirements, and thereby makes an SCR systems feasible for use in mobile emissions control systems.

Abstract: A fuel adding valve (14), an HC adsorbing and oxidation catalyst (11), and a NOx storing catalyst (12) are successively arranged in an exhaust passage of an internal combustion engine toward the downstream side. When the NOx storing catalyst (12) should release NOx, particulate fuel is added from the fuel adding valve (14). This fuel is adsorbed once at the HC adsorbing and oxidation catalyst (11), then gradually evaporates to make the air-fuel ratio of the exhaust gas flowing into the NOx storing catalyst (12) rich. Due to this, NOx is released from the NOx storing catalyst (12).

Abstract: A heat regenerative engine uses water as both the working fluid and the lubricant. In operation, water is pumped from a collection pan and through a coil around a cylinder exhaust port, causing the water to be preheated by steam exhausted from the cylinder. The preheated water then enters a steam generator and is heated by a combustion chamber to produce high pressure super heated steam. Air is preheated in a heat exchanger and is then mixed with fuel from a fuel atomizer. An igniter burns the atomized fuel as the flames and heat are directed in a centrifuge within the combustion chamber. The speed and torque of the engine are controlled by a rocker and cam arrangement which opens a needle-type valve to inject high pressure super heated steam into a cylinder having a reciprocating piston therein. The injected steam expands in an explosive action on the top of the piston at high pressure forcing the piston down and drivingly rotating a linked crank cam and crankshaft.

Abstract: In a method for synchronizing drive units, a target value of the speed of each drive unit of a plurality of drive units speed is computed by determining the product of a maximum speed of the drive unit, a unit-dependent normalized ratio value of the drive unit, and a synchronization factor which is identical for all drive units. The ratio value defines the relative speeds of the individual drive units. Changing the synchronization factor causes synchronous speed changes of the drive units. As a result, a lasting synchronization can be realized across the entire speed spectrum.

Abstract: Methods and devices for the management of cryogenic agents within analytical systems using freeze thaw valving having an expansion chamber that limits the flow of the cryogenic agent. The expansion chamber is fitted with an expansion nozzle through which a cryogen flows and a porous frit that allows the cryogen to be exhausted. The porous frit initially allows a rapid flow of cryogen into the expansion chamber. This rapid flow lowers the temperature of the expansion chamber causing fluid contents within a freeze thaw segment to freeze. As the cryogen expands into the expansion chamber and turns into a solid, the porous frit is occluded causing the rapid flow to be restricted. The restriction of the cryogen flow by the occlusion of the porous frit allows the freeze thaw valve to use significantly less cryogen. Sublimation of the cryogen trapped within the porous frit provides sufficient cooling to maintain the valve in its closed position.
