Assignee:

Ford Motor Company - Dearborn MI

International Classification:

F02N 1104

US Classification:

180 652, 180 653, 180 658

Abstract:

An internal combustion engine ( ) having a crankshaft ( ) is coupled to a transmission ( ) through an assembly ( ) comprising a rotary electric machine ( ) and an engine disconnect clutch ( ). The stator ( ) and rotor ( ) of the machine are separated by a radial air gap ( ), and the machine is selectively operable as an electric motor to source torque to the powertrain and as an electric generator, or alternator, to sink torque from the powertrain. The organization and arrangement provides a powertrain and method of making a powertrain for establishing and maintaining precision in the radial air gap to secure optimal efficiency of machine operation on a production basis.

Abstract:

Freeze protection of an on-board emissions treatment substance storage and distribution system in a vehicle includes moving the emissions treatment substance away from a primary fuel/vapor area after filling of the emissions treatment system. In one embodiment an on-board emissions treatment system has a fill tube with a portion extending into a primary fuel fill pipe to facilitate co-fueling of the primary fuel and emissions treatment substance. A pressure differential or vacuum is created in the emissions treatment fill tube after filling to move the emissions treatment substance away from a check valve disposed at the terminal end of the fill tube to prevent freezing of the check valve after filling. The emissions treatment substance may be moved out of the co-located portion of the fill tube to an area where passive or active heating of the fill tube may be applied.

Abstract:

According to one aspect of the present invention, a liquid reductant tank for supplying liquid reductant to a selective catalytic reduction system is disclosed. The tank includes a tank cavity for holding a liquid reductant and being at least partially defined by one or more side walls; a liquid reductant supply line at least partially situated within the tank cavity and for communicating liquid reductant from the tank cavity to outside of the tank cavity; and a heating element situated at least partially within the liquid reductant supply line and for thawing frozen reductant situated within the supply line during cold start conditions to obtain liquid reductant for use in a selective catalytic reduction system.

Abstract:

A system and method for treating exhaust gasses from an engine is described. In one example, the exhaust gasses are routed from the engine to atmosphere through a helical exhaust passage. The helical exhaust passage includes a plurality of spatially separated exhaust passages that separates the exhaust flow into separated smaller flows, wherein the smaller flows are re-introduced into a common passage and re-combined to form a single exhaust flow, and wherein the plurality of spatially separated exhaust passages induces a helical flow pattern within the re-combined exhaust flow.

US Classification:

60286, 60274, 60287, 60297, 60301, 60303

Abstract:

Systems and methods are provided for injecting liquid reductant into an engine exhaust. An example system includes a gas deflector positioned upstream of an injector where the gas deflector is configured to create a high pressure zone upstream of the deflector and a low pressure zone downstream of the deflector surrounding the injector outlet. A bypass flow passage diverts exhaust flow from the high pressure zone upstream of the deflector to allow the bypassed portion of exhaust to flow into the exhaust gas stream to form a gas shield for a liquid reductant spray from the injector. In this way, it is possible to reduce deposit formation and accumulation in the exhaust system.
