Patent number: 6675771Abstract: A control system must establish the same throttle position repeatedly to obtain fuel efficiency and prevent speed dropping during idling. Sensors determine the throttle position or other engine parameter associated with the throttle position and create an analog signal. The information is processed by a analog-to-digital converter which places the signal into a discrete level. A controller receives this signal and compares it to a point assigned between two discrete levels representing the desired throttle position or engine parameter. Therefore, the signal will never equal the assigned point. The controller makes corrections based on this comparison after every iteration because the error will never reach zero.Type: GrantFiled: December 28, 2001Date of Patent: January 13, 2004Assignee: Visteon Global Technologies, Inc.Inventor: Ross D.

The air ionizer, which functions with either gasoline or diesel fuel engines is operated by an electronic ionizer control unit (12). The unit (12) is located within the confines of the vehicle's engine compartment and is operated by a 12-volt d-c power source (104) derived from the vehicle's battery (102). When air from the vehicle air-intake hose (106) Passes through the air ionizer (12) the air is ionized and is mixed with the non-ionized air to produce an oxygen-enriched fuel-air mixture. The oxygen-enriched mixture allows a fuel saving and produces a cleaner burning fuel which reduces hydro-carbon exhaust emission levels.Type: GrantFiled: September 24, 2002Date of Patent: January 13, 2004Inventors: Antonius G. Wendels, John W. Frencher

Patent number: 6675781Abstract: A system to cool the charge air of an engine including a cylinder, a cylinder valve, a delivery hose, a cryogen, an aerodynamic, hollow heat exchanger with inlet and outlet ports which is charged or frozen by passing the cryogen such as nitrous oxide, carbon dioxide, nitrogen or other such gas or liquid with cryogenic properties through the device. The heat is transferred from the body of the heat exchanger to the circulating cryogen thus freezing the body of the heat exchanger. The heat exchanger is installed in the charge air flow as not to disrupt the flow and the heat from the charge air is transferred to the frozen heat exchanger as they come in contact. The heat exchanger can be installed into the existing charge air intake system or be preinstalled in an attachable segment of air charge tube that can be mounted into the current charge air intake system of an engine.Type: GrantFiled: November 14, 2002Date of Patent: January 13, 2004Inventor: David Lee Markley

Patent number: 6675782Abstract: Supercharged internal combustion engine with two separate exhaust manifolds (2a,2b) from individual cylinder groups and two separate inlet manifolds (3a,3b) each leading to a respective cylinder group. An inlet conduit (9) from a supercharger (6) leads to an equalising chamber (11), from which two tuned resonance tubes (12,13) lead to the inlet manifolds. From the exhaust manifolds a pair of exhaust recirculation conduits (19a,21a,19b,21b), each containing a control valve (18a,18b) controlled by a control unit (16) for controlling the exhaust recirculation, lead to the inlet manifolds. The control unit is disposed to open the control valves when the exhaust pressure is higher than the pressure in the inlet manifolds.Type: GrantFiled: September 10, 2001Date of Patent: January 13, 2004Assignee: Volvo Lastvagnar ABInventor: Per Persson

Patent number: 6675784Abstract: In an engine ignition system having a fail-safe function, a battery, a coil and a transistor are connected in series. A capacitor is connected to the coil by way of a diode. The capacitor, a primary winding of an ignition coil and a transistor are connected in series. A transistor and a diode in serial connection are connected in parallel to the coil and diode in serial connection. A drive circuit turns on and off the transistor to charge the capacitor and operates the transistor to implement the ignition operation. The drive circuit, in the event of system failure, turns on and off the transistor, while retaining the transistor in the on state, thereby to feed energy of the battery to the primary winding.Type: GrantFiled: October 16, 2001Date of Patent: January 13, 2004Assignee: Denso CorporationInventors: Noboru Nagase, Tetsuya Miwa, Makoto Toriyama

Patent number: 6675785Abstract: An insulator includes a coil side cylindrical portion extending from a plug side cylinder portion in a direction departing from a combustion chamber. One end of the coil side cylindrical portion protrudes in the direction departing from the combustion chamber with respect to a primary winding and a secondary winding. A pressure sensing element is disposed next to the one end of the coil side cylindrical portion. The signal lines of the pressure sensing element are taken out of a casing without passing aside an ignition coil. Thus, the diameter of the casing does not increase. The output signal of the pressure sensing element is not adversely influenced by discharge noises generated from the ignition coil.Type: GrantFiled: March 27, 2003Date of Patent: January 13, 2004Assignee: Denso CorporationInventors: Tetsuya Miwa, Atsuya Mizutani, Takeo Maekawa, Hiromi Hiramatsu, Tohru Yoshinaga

Patent number: 6675786Abstract: In an ignition coil assembly, a plurality of ignition coils is arranged to be electrically connected to spark plugs received in plug holes of an engine. A base cover supports the ignition coils at corresponding positions, which correspond to positions of the plug holes, respectively. A top cover covers a top surface of the base cover. Connecting bolts connects between the top cover and the base cover. Fastening bolts secures only the base cover to the engine.Type: GrantFiled: June 11, 2003Date of Patent: January 13, 2004Assignee: Denso CorporationInventors: Koji Tsunenaga, Atsuyuki Konishi

Patent number: 6675787Abstract: A device and a method are described for controlling an internal combustion engine, in which a control deviation and a governor are allocated to each cylinder of the internal combustion engine, each governor preselecting a cylinder-specific triggering signal on the basis of the allocated control deviation. Cylinder-specific actual values are ascertained on the basis of a signal from a sensor arranged in the exhaust train and are compared to a setpoint value. Triggering signals for the cylinder-individual control of the fuel quantity and/or air quantity are preselected on the basis of the comparison.Type: GrantFiled: December 17, 2001Date of Patent: January 13, 2004Assignee: Robert Bosch GmbHInventors: Jens Damitz, Dirk Samuelsen, Ruediger Fehrmann, Matthias Schueler

Patent number: 6675789Abstract: A control agent delivery system useful for dispersing a pesticide, herbicide, fungicide or other biocide around a target or target area that is not directly accessible or that is hazardous to the user. The system includes a separable, two-part projectile containing a control agent disposed in a powder, liquid or gel dispersal medium, together with a gas-propelled, projectile launching device. A method of use of the subject system that causes the projectile to perform differently, depending upon the manner of launch, is also disclosed.Type: GrantFiled: August 15, 2001Date of Patent: January 13, 2004Assignee: NCH CorporationInventors: Robert Clarence Pearce, III, Dale Vilmer Kiplinger
