20090216425 | CONTROL SYSTEM AND METHOD FOR STARTING AN ENGINE WITH PORT FUEL INJECTION AND A VARIABLE PRESSURE FUEL SYSTEM - A fuel control system includes a pressure comparison module that generates a pressure control signal when a fuel supply pressure is greater than a predetermined pressure value, a temperature comparison module that generates a temperature control signal when a temperature of an engine is greater than a predetermined temperature value, and a pre-crank fuel module that selectively dispenses pre-crank fuel prior to cranking the engine based on the pressure control signal and the temperature control signal. A related fuel control method is also provided. | 08-27-2009 |
20130124144 | PRESSURE DIAGNOSTIC SYSTEM AND METHOD - A pressure diagnostic system includes a pressure error calculating module that generates a pressure error based on a first pressure signal and a second pressure signal. A difference calculating module generates a desired pressure difference based on a current desired pressure and a prior desired pressure. A lag filter module applies lag filter to the pressure error to generate a lag filtered pressure error. A fault module selectively generates a fault based on the lag filtered pressure error. | 05-16-2013 |
20140100728 | METHOD OF CONTROLLING CATALYST LIGHT-OFF OF A HYBRID VEHICLE - A method of warming a catalyst of an exhaust gas treatment system of a hybrid vehicle includes transitioning a rotational speed of an engine to within a pre-defined speed range with an electric motor, and reducing an engine manifold pressure to within a pre-defined pressure range. The engine is fueled after the rotational speed of the engine is within the pre-defined speed range, and the engine manifold pressure is within the pre-defined pressure range. While the engine is being fueled, the engine manifold pressure is increased to within a catalyst light-off pressure range, and the torque output of the engine is increased to within a catalyst light-off operating torque range. The exhaust gas produced from the operation of the engine within the pre-defined speed range, within the catalyst light-off pressure range, and within the catalyst light-off operating torque range heats the catalyst while minimizing emissions. | 04-10-2014 |

20080290567 | Rotary Charging Device for a Shaft Furnace Equipped with a Cooling System - A rotary charging device for a shaft furnace, in particular a blast furnace, is disclosed. The charging device is equipped with a cooling system. The rotary charging device includes a rotatable support for rotary distribution means as well as a stationary housing for the rotatable support. The cooling system includes a rotary cooling circuit fixed in rotation with the rotatable support as well as a stationary cooling circuit on the stationary housing. A heat transfer device is provided which includes a stationary heat transfer element configured to be cooled by a cooling fluid flowing through the stationary cooling circuit and which includes a rotary heat transfer element configured to be heated by a separate cooling fluid circulated in the rotary cooling circuit. These heat transfer elements are arranged in facing relationship and have there between a heat transfer region for achieving heat transfer by convection and/or radiation through the heat transfer region without mixing of the separate cooling fluids of the rotary and stationary cooling circuits. | 11-27-2008 |
20090087284 | THREE HOPPER CHARGING INSTALLATION FOR A SHAFT FURNACE - A three hopper charging installation for a shaft furnace includes a rotary distribution device for distributing bulk material in the furnace by rotating a distribution member about the furnace central axis and a first, a second and a third hopper arranged in parallel above the rotary distribution device and offset from the central axis. A sealing valve housing is arranged between the hoppers and the distribution device. It has a top part with a first, a second and a third inlet respectively communicating with the first, the second and the third hopper. A first, a second and a third sealing valve are provided in the top part. Each sealing valve includes a flap which is pivotable between a closed sealing position and an open parking position. The sealing valve housing also has a funnel shaped bottom part with an outlet communicating with the distribution device. According to the invention, the top part of the sealing valve housing has a tripartite stellate configuration in horizontal section with a central portion, in which the inlets are arranged adjacently in triangular relationship about the central axis, and with a first, a second and a third extension portion, each sealing valve being adapted such that its flap opens outwardly with respect to the central axis by pivoting into a parking position located in the first, second or third extension portion respectively. | 04-02-2009 |
20100119986 | MULTIPLE HEARTH FURNACE - A multiple hearth furnace includes a gas cooling system for its central shaft and its rabble arms. This gas cooling system includes within the shaft an annular main distribution channel for supplying a cooling gas to the rabble arms and a central exhaust channel for evacuating the cooling gas leaving the rabble arms. The gas cooling system further includes an annular main supply channel surrounding the annular main distribution channel and being outwardly delimited by an outer shell of the shaft. A cooling gas inlet is connected to the annular main supply channel. A cooling gas passage between the annular main supply channel and the annular main distribution channel is spaced from the cooling gas inlet, so that cooling gas supplied to the cooling gas inlet has to flow through the annular main supply channel through several hearth chambers before it flows through the cooling gas passage into the annular main distribution channel. | 05-13-2010 |
