Abstract:

A control system for engine braking for a vehicle powered by a turbocharged engine uses a supercharger to assist a turbocharger compressor to boost turbocharger air flow into the engine cylinders. An engine driven air pumping device draws ambient air, or alternately exhaust gas through the pump inlet, compresses the air, and delivers the compressed air through the pump outlet to the turbocharger compressor inlet or alternately the turbocharger compressor outlet. The increased air flow into the cylinders and out of the cylinder exhaust valves increases retarding power of the vehicle.

US Classification:

423210, 422168

Abstract:

A method for injection of a liquid reductant () into an exhaust gas () and for evaporating and decomposing the liquid reductant at an elevated temperature includes providing an exhaust pipe () having an interior surface () and disposing the exhaust pipe in fluid communication with and upstream of a catalyst (). The method also includes the steps of disposing an internal cone () within the exhaust pipe () generally parallel to the exhaust pipe, mounting an injector () to the exterior of the exhaust pipe in fluid communication with the internal cone, injecting the liquid reductant into the internal cone, and directing the exhaust gas () in a passage between the interior surface () of the exhaust pipe and the internal cone. The exhaust gas () is also directed within the internal cone (). The flow of exhaust gas () has an elevated temperature compared to an ambient. A further step includes creating a drag force on the injected liquid reductant () to increase the travel time of the injected liquid reductant from the injector () to the catalyst ().

Abstract:

A modular system for constructing a coolant core/cylinder head structure, is described. The system comprises a modular coolant core having an inlet and an outlet, a plurality of passageways within an interior space of the coolant core, the passageways fluidly connecting, which create a specific coolant flow pattern between the inlet and the outlet, wherein the coolant core has a single pattern geometry for assembling into the cylinder head core box. Use of the individual modular coolant cores permits construction of customized cylinder heads, which use the same tooling across multiple engine platforms, while providing more uniform coolant velocity and heat rejection from cylinder to cylinder and improved structure with more uniform clamping load between head bolts around the combustion chamber.
