20090057445 | LOW PRESSURE FUEL INJECTOR NOZZLE - A nozzle for a low pressure fuel injection that improves the control and size of the spray angle, as well as enhances the atomization of the fuel delivered to the cylinder for an engine. | 03-05-2009 |
20090057446 | LOW PRESSURE FUEL INJECTOR NOZZLE - A nozzle for a low pressure fuel injection that improves the control and size of the spray angle, as well as enhances the atomization of the fuel delivered to the cylinder for an engine. | 03-05-2009 |
20090090794 | LOW PRESSURE FUEL INJECTOR - A low pressure fuel injector capable of atomizing fuel at relatively low pressure is configured to have reduced hydraulic resistance. Reduction in the hydraulic resistance minimizes the pressure drop within the fuel injector and thereby improves atomization of the fuel for improved fuel economy and performance, and decreased emissions. | 04-09-2009 |
20090200403 | FUEL INJECTOR - A fuel injector having a nozzle with depressions for increasing fluid turbulence and preventing deposit build up within the injector to increase performance, longevity and fuel economy. | 08-13-2009 |
20100074743 | Air Diffuser For a HVAC System - A diffuser for carrying air flow to an evaporator in an air conditioning system of an automotive vehicle includes an inlet and an outlet, a wall extending between the inlet and the outlet, and a guide vane, extending at least partially between the inlet and the outlet, spaced from the wall by a containing a control region whose area ratio changes along a length of the guide vane. | 03-25-2010 |
20120034077 | HVAC Diffuser With Mounting Receptacle for Variable Blower Control - An automotive HVAC diffuser connects to a blower and a variable blower control (VBC) module having a plurality of cooling fins. An inlet receives air flow from the blower. An outlet is downstream from the inlet. An enclosed passageway is provided between the inlet and the outlet for forming a diffused air stream at the outlet. The enclosed passageway has a plurality of peripheral walls for guiding the air stream between the inlet and the outlet, including a curved outer peripheral wall corresponding to a region with a tendency for a high flow as a result of centrifugal effects. One of the peripheral walls includes a VBC receptacle formed as a depression into the peripheral wall having a substantially flat mounting surface and a first sloped side at an upstream end of the VBC receptacle to shape a portion of the diffused air stream. The flat mounting surface includes a plurality of cooling fin receiving slots arranged to receive the cooling fins, whereby the cooling fins extend into an interior of the diffused air stream. | 02-09-2012 |
20120034859 | HVAC Air Inlet with Blend Mode and Fresh-Restricted Mode - An air inlet system for an automotive HVAC system has a housing comprising a first cylindrical segment enclosing an interior space and having a first radial surface with a first angular divergence. The first radial surface has a fresh air aperture and a recirculation aperture for radially receiving fresh air and recirculated air, respectively. The housing further comprises an outlet body with an exit aperture. A pivoting door element is mounted in the interior space and shaped as a second cylindrical segment with a second radial surface with a second angular divergence which is less than the first angular divergence. The door element has a pivot axis that allows the second radial surface to slide along the first radial surface. The door element pivots to selectably align the opening with the fresh air aperture or the recirculation aperture in order to 1) block the fresh air aperture without blocking the recirculation aperture, 2) simultaneously block portions of the fresh air aperture and the recirculation aperture, 3) block the recirculation aperture without blocking any of the fresh air aperture, or 4) block the recirculation aperture while blocking only a portion of the fresh air aperture. | 02-09-2012 |
20120168117 | Automotive HVAC Diffuser With Cooperating Wall Guide And Vane - A case for an HVAC system has at least two molded shells joined together along a parting line to enclose a heat exchanger chamber, a blower chamber, and a diffuser section. The diffuser section includes a floor, a ceiling, an outer wall, and an inner wall around a longitudinal axis. The walls provide an airflow path through the diffuser between the blower and heat exchanger chamber, and the airflow path makes a substantially right angle turn into the heat exchanger chamber which results in a tendency to create a high flow region at the outer wall because of centrifugal effects. The outer wall is shaped to form a wall guide partially projecting into the airflow path in the diffuser, wherein the wall guide has an upstream encroaching surface and a downstream retreating surface so that a portion of the guided air is directed from the outer wall toward the inner wall. At least one of the floor or the ceiling includes a vane projecting into and deflecting the guided air in the airflow path, wherein the vane has an upstream end proximate to the wall guide and a downstream end extending toward the heat exchanger chamber for initiating a portion of the substantially right angle turn for a portion of the airflow. | 07-05-2012 |
