Abstract: A reductant delivery unit (10) is provided for selective catalytic reduction (SCR) after-treatment for vehicles. The unit includes a solenoid fluid injector (10) constructed and arranged to be associated with an exhaust gas flow path (14) upstream of a SCR catalytic converter (17). The fluid injector has a fluid inlet (13) and a fluid outlet (15) with the fluid inlet being constructed and arranged to receive a source of urea solution and the fluid outlet being constructed and arranged to communicate directly with the exhaust flow path so as to control injection of urea solution into the exhaust gas flow path. An interface (24) is constructed and arranged to couple the fluid injector to the gas flow path. The interface defines a thermal barrier constructed and arranged to decoupled a body of the injector from exposure to heat in the exhaust gas flow path.

Abstract: A fluid sensor arrangement (20) includes a sleeve (32) that is adapted to be placed within a container (24). A plurality of conductors (46, 48) and a channel member (50) within the sleeve cooperate to provide a measurement of conductivity of the fluid within the sleeve (32). The conductivity measurement provides an indication of a level of fluid within the container (24). A disclosed example includes a non-conductive channel member (50) having an opening or a channel (52) for directing selected portions of a conductivity field within the sleeve (32) between the conductors (46, 48) for making the conductivity determinations.

Abstract: A method and fuel injector for precision setting of valve lift, using a valve body shell (42) telescoped over the valve body (60), the shell (42) having a nonmagnetic extension welded to the valve body shell (42) and to the end of an inlet tube (16) providing a solenoid pole piece, with the valve body (60) and shell (42) adjusted to set the valve lift and thereafter welded together. Interference fit portions stabilize the adjusted position of the members preparatory to welding, and displaced material in a locking groove (102) creates a mechanical interlock between the valve body (60) and shell (42) to stabilize the members in their adjusted positions after welding so that the set lift is minimally affected by weld shrinkage. An external radial groove 18 allows radial bending as the weld cools to minimize axial shift of the parts and thus the effect on the set valve lift.
