Publication number: 20210049831Abstract: An onboard real-time lap, segment, section and start (“holeshot”) time measuring and feedback system for racing is provided. The system further provides a communication link between a third party (mobile device, team/team members, other participants) and the racer. The system digitally recreates and enhances what is known as a “pit board” or manual written means of communicating with the user. Additional training features are optionally provided. Post-race/practice data may then be uploaded to a mobile device for further analytics and comparison amongst other racers, athletes and/or other users.Type: ApplicationFiled: August 14, 2020Publication date: February 18, 2021Inventors: Robert Edward POLLAK, III, Nicholas FEKETE, Tyler MEDAGLIA, ZhenHao WU

Patent number: 7337771Abstract: In a method and apparatus for the cylinder-specific determination and control of a fuel injection quantity for a multi-cylinder internal combustion engine, the exhaust gas pressures of the cylinders of the internal combustion engine is recorded on a time-resolved, i.e. crankshaft angle-resolved, basis, and an exhaust gas pressure is calculated therefrom individually for each cylinder and used to determine the fuel quantity injected into the corresponding cylinder. In a comparison with a desired value the cylinder-specific actual fuel injection quantity error is then determined and used to set a corrected quantity of fuel to be injected into the corresponding cylinder.Type: GrantFiled: June 13, 2006Date of Patent: March 4, 2008Assignee: Daimler Chrysler AGInventors: Joachim Bornitz, Nicholas Fekete, Lorenzo Matassini, Ruediger Pfaff

Publication number: 20060151628Abstract: The invention relates to a nozzle needle 4 of an injection nozzle 1, which is disposed within an injector housing and is biased against a housing shoulder 5 by way of a spring 2. A piezo-element 7 is between the spring 2 and the housing shoulder 5, to determine the nozzle needle path during opening and closing of the nozzle opening 3. For this purpose, the piezo-element 7 has two electrical connectors 8.1, 8.2 in the region of the faces 7.1, 7.2, respectively.Type: ApplicationFiled: May 6, 2003Publication date: July 13, 2006Inventors: Nicholas Fekete, Tobias Flamig-Vetter, Dirk Herbstritt

Publication number: 20060064231Abstract: The invention relates to a method and a corresponding apparatus for detecting the rotational speed of turbochargers, especially on internal combustion engines in motor vehicles, with the steps: recording the body sound (SE) of the turbocharger and analyzing the frequency spectrum (30, 31, 32, 33) of the recorded body sound (SE). According to the invention, in the analysis of the frequency spectrum several frequency signals (SD1, SD2, SD3) are determined, which represent possible rotational speeds of the turbocharger, an amplitude analysis of the recorded body sound (SE) is performed in order to determine an estimated value (SD-estimate) for the turbocharger speed, and the estimated value (SD-estimate) is correlated with the several frequency signals (SD1, SD2, SD3) in order to determine the frequency signal (SD2) as the actual turbocharger rotational speed (Dactual) which correlates with the greatest probability with the obtained estimate (SD-estimate).Type: ApplicationFiled: March 2, 2005Publication date: March 23, 2006Applicant: DaimlerChrysler AGInventors: Nicholas Fekete, Lorenzo Matassini

Patent number: 6308517Abstract: A system for automatic charging pressure control using an exhaust gas turbocharger with a variably adjustable turbine cross-section and for automatic exhaust gas recirculation control in the case of an internal-combustion engine, particularly a diesel engine. An automatic control system has a first controller which has an output for the variation of the turbine cross-section of the exhaust gas turbocharger. The command variable for the automatic exhaust gas recirculation control in a first low load-rotational speed range is the air flow rate in the intake pipe. The command variable for the automatic charging pressure control in a second higher load-rotational speed range is the charging pressure in the intake pipe. For the automatic exhaust gas recirculation control, an exhaust gas recirculation pipe connects the exhaust gas pipe with the suction pipe.Type: GrantFiled: January 19, 1999Date of Patent: October 30, 2001Assignee: Daimler Chrysler AGInventors: Hans Fausten, Nicholas Fekete, Thomas Muehleisen, Stefan Pischinger, Siegfried Weber

Patent number: 6298728Abstract: An arrangement for detecting the turbocharger rotational speed on internal-combustion engines is provided with at least one piezoelectric acceleration sensor fixed on the turbocharger and with an analyzing circuit having an analog filter arrangement for filtering the output signals of the acceleration sensor. The output signals of the filter arrangement are fed by way of a frequency-to-voltage converter in the form of an analog voltage, or directly in the form of frequency signals, as input signals to an electronic control unit of the internal-combustion engine or to a measuring and/or display unit. As a result, the turbocharger rotational speed can be detected at a reasonable cost with a small and robust arrangement suitable for mass production and requiring no constructional changes on the turbocharger.Type: GrantFiled: April 22, 1999Date of Patent: October 9, 2001Assignee: DaimlerChrysler AGInventors: Nicholas Fekete, Karsten Finger, Lothar Welte

Patent number: 6209316Abstract: The invention relates to a method of operating a diesel engine having an engine controller which controls the operation of the diesel engine as a function of characteristic maps and permits rich/lean control of the diesel engine. The engine controller includes a computer which effects a changeover to rich or lean operation of the diesel engine as a function of predetermined changeover criteria, a sensor system which communicates with the computer and monitors parameters needed for changeover criteria, and a memory which communicates with the computer and in which the characteristic maps for operating the diesel engine are stored. The computer effects a changeover from lean to rich operation when all the changeover criteria in this respect are satisfied, and effects a change back from rich to lean operation when at least one of the changeover criteria in this respect is satisfied.Type: GrantFiled: November 5, 1999Date of Patent: April 3, 2001Assignee: DaimlerChrysler AGInventors: Frank Duvinage, Hans Fausten, Nicholas Fekete, Anton Kerckhoff, Bernd Krutzsch, Thomas Liebscher, Stefan Pischinger, Michel Weibel
