Patent number: 6711996Abstract: A hay conditioning apparatus includes a first roller which is rotatably mounted in a fixed mounting and a second counter-rotating (compression) roller which is rotatably mounted in connection with a moveable mounting. The compression roller is in rolling contact with the first roller and is adapted to receive pre-cut hay therebetween for conditioning. The moveable mounting allows the compression roller to be displaced relative to the first roller as the hay passes between the rollers and also includes a hydraulic cylinder for applying a compression force to the compression roller. As the pre-cut hay passes between the rollers, it is subjected to a predetermined compression force sufficient to substantially flatten any green nodes on the hay and thereby accelerate drying of the hay.Type: GrantFiled: June 7, 2002Date of Patent: March 30, 2004Assignee: Mackie International Pty LtdInventor: Peter Gilbert Mackie

Patent number: 6712032Abstract: Method for heating an electrical heating element, for example, a glow plug for an internal combustion engine, from an initial temperature to the operating temperature. In order to prevent the heating element from overheating in cases where the initial temperature is higher than a set temperature that is normally taken as a basis, the actual initial temperature of the heating element is first determined, and an amount of electrical power depending on the level of the determined initial temperature is supplied to the heating element. In this way, the supplied amount of electrical power is reduced at higher initial temperatures, thus preventing the heating element from becoming overheated to a temperature at which damage can occur.Type: GrantFiled: September 27, 2002Date of Patent: March 30, 2004Assignee: Beru AGInventors: Günther Uhl, Olaf Toedter, Heinz-Georg Schmitz

Patent number: 6712035Abstract: Ignition delay in a diesel engine is reduced or eliminated by a fuel injector or igniter nozzle which includes energy supplying fuel conditioning means at the point of fuel injection into a cylinder. A preferred embodiment includes an electrically-conductive injection valve reciprocable in a conductive nozzle body and seatable on a valve seat to stop fuel flow through nozzle orifices. The injection valve is electrically insulated from the body except at its contact with the valve seat and is connected to an electrical charge, at least during opening of the valve. An electrical spark discharge is thus generated between the injection valve and the valve seat upon opening of the valve. Initially injected fuel passes through the arc and is conditioned by the spark energy to ignite almost immediately by compression ignition upon entering the engine cylinder and thus essentially eliminate diesel ignition delay.Type: GrantFiled: March 26, 2002Date of Patent: March 30, 2004Assignee: General Motors CorporationInventors: Paul Gottemoller, Richard Wayne Tupek, Michael Barry Goetzke, Jerry Van Polen, David Corba, Wojciech T.

Patent number: 6712036Abstract: A method of controlling the fuel injection in an internal combustion engine (1) having a piston (3), which passes to and for in a cylinder (2) between an upper and a lower dead center, and an injection nozzle (4), which is disposed in the cylinder (2), the method including the steps whereby a primary injection of fuel is realized in the cylinder (2), which fuel is ignited and causes the piston (3) to be moved in the direction of the lower dead center in the cylinder (2), and whereby a post-injection of a fluid is realized in the cylinder (2). The injection pressure of the fluid in the post-injection is higher than the injection pressure of the fuel in the primary injection.Type: GrantFiled: August 6, 2002Date of Patent: March 30, 2004Assignee: AB VolvoInventors: Arne Andersson, Anders Hoglund, Jan Eismark, Bo Svensson

Patent number: 6712037Abstract: A low pressure direct injection engine system for a vehicle includes an engine having a plurality of cylinders each including a piston wherein the cylinders and a top portion of the pistons define a plurality of combustion chambers. A fuel injector is mounted in fluid communication with each of the combustion chambers. Each fuel injector has a nozzle which is adapted to generate a fine fuel spray with droplet sizes of 25 micro-meters SMD and 45 micro-meters DV90 and low penetration at fuel pressure of roughly 2 MPa. A low pressure fuel delivery system is adapted to deliver fuel from a fuel tank within the vehicle to the fuel injectors, and an igniter is mounted within the combustion chamber which is adapted to ignite the fuel within the combustion chamber.Type: GrantFiled: January 9, 2002Date of Patent: March 30, 2004Assignee: Visteon Global Technologies, Inc.Inventor: Min Xu

Patent number: 6712038Abstract: An intake device of an internal combustion engine is provided that includes an intake flow control valve shaped so as to be capable of effectively forming a tumble flow within a combustion chamber when there is a projection within an intake pipe located downstream of the intake flow control valve. The intake device of the internal combustion engine includes an intake flow control valve between a throttle valve provided within an intake pipe and a fuel injector located downstream of the throttle valve, for producing a tumble flow in a combustion chamber. The intake flow control valve includes a valve body. The valve body has a bypass airflow producing portion formed at a position corresponding to that of the fuel injector (i.e., a projection within the intake pipe) when viewed in a flow direction of the airflow.Type: GrantFiled: March 7, 2002Date of Patent: March 30, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keizo Hiraku, Toshiki Annoura, Hideki Suzuki

Patent number: 6712040Abstract: A variable valve comprising a first cylinder having a first aperture and a second cylinder having a second aperture. The first cylinder moves between a first position and a second position. Preferably, the second cylinder moves in cooperation with the first cylinder such that the first aperture and the second aperture form a variable sized opening when the first cylinder moves from the first position toward the second position. The first aperture and the second aperture preferably rotate. The variable sized opening is preferably in a closed position when in the first position. The valve comprises a block body including a passage for allowing air to pass. therethrough. The first cylinder and the second cylinder are coupled to the block body and configured in a predetermined position such that the variable sized opening is in communication with the passage. The valve also includes an axle for driving the first cylinder and the second cylinder.Type: GrantFiled: January 21, 2003Date of Patent: March 30, 2004Inventor: John Giffin

Patent number: 6712041Abstract: A method for controlling an engine having both an electronically controlled inlet device, such as an electronic throttle unite, and an electronically controlled outlet device, such as a variable cam timing system is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by coordination of the inlet and outlet device. This improved control is used to improve various engine control functions.Type: GrantFiled: October 18, 1999Date of Patent: March 30, 2004Assignee: Ford Global Technologies, Inc.Inventors: John David Russell, Allan Joseph Kotwicki, Brian D.
