Abstract: A fluid-cooled manifold is configured to cool exhaust from an engine. The fluid-cooled manifold includes a plurality of exhaust runners. Each of the exhaust runners includes a runner body having an inlet end and an outlet end, an exhaust conduit extending through the runner body, and a coolant passage extending through the runner body. The fluid-cooled manifold also includes an exhaust collection manifold including a plurality of inlets. Each inlet of the exhaust collection manifold is coupled to the exhaust outlet opening of a respective one of the exhaust runners. The fluid-cooled manifold also includes a coolant feed pipe and a coolant exit pipe. The coolant feed pipe includes a plurality of outlets coupled to the coolant inlets of the exhaust runners. Likewise, the coolant exit pipe includes a plurality of inlets coupled to the coolant outlets of the exhaust runners.

Abstract: A turbocharger bypass system and method for minimizing the occurrence of oil seepage from the bearing housing into the compressor housing as a result of a pressure differential across the bearing housing and the compressor housing. A bypass system with a pressure dependent check valve is connected to the inlet air passage of a turbocharged engine. When the pressure in the inlet air passage drops to below atmosphere or a predetermined level of depression, the check valve opens to allow a flow of atmospheric air into the inlet air passage, thus minimizing or eliminating the pressure differential generated as a result of a vacuum in the inlet air passage during motoring conditions, or when an exhaust valve downstream of the turbocharger is closed, such as during engine braking. The bypass system is applicable to both single stage and dual stage turbocharged internal combustion engines.

Abstract: An exhaust gas aftertreatment system (10) for a vehicle having an engine (14) includes a fluid passageway (20) extending from the engine to an ambient (18) for fluidly communicating exhaust gas (F). A diesel particulate filter (30) is disposed on the fluid passageway downstream of the engine (14). Disposed downstream of the engine (14) and upstream of the diesel particulate filter (30) is an electric diesel oxidation catalyst (24) having a substrate (34). A first electrode (40) and a second electrode (46) are attached to the electric diesel oxidation catalyst (24). The first electrode (40) selectively delivers current through the substrate (34) to the second electrode (46) to generate heat at the substrate (34).

Abstract: A gravity-activated valve for use in supplying an uninterrupted supply of fluid is disclosed. The valve includes a housing having an outlet, an inlet positioned below the outlet, and a sleeve disposed within the housing. The valve also includes a buoyant piston disposed within the sleeve, which is adapted to move between an open position and a closed position. The piston is positioned above the outlet when the piston is in the open position to allow fluid flow through the outlet and positioned proximate the outlet in the closed position to prevent fluid flow through the outlet. The piston is in the open position when the fluid level exceeds a predetermined fluid level and in the closed position when the fluid level is at or below the predetermined fluid level. The valve further includes a plurality of gaskets, which are adapted to create a seal between the piston and the sleeve.
