Patent number: 6941219Abstract: An engine control module, and method for operating the same for controlling an internal combustion engine. The engine control module comprising a processor for executing instructions to controlled the engine. The engine control module partitioning its memory used to store calibration data. The memory is partitioned into user-changeable and non-user-changeable portions. Only the user-changeable portions are repeatedly backed up. These portions are backed up such that the engine control module can recreate valid calibration data when a memory failure has occured and the engine control module.Type: GrantFiled: September 30, 2003Date of Patent: September 6, 2005Assignee: Detroit Diesel CorporationInventors: Richard M. Avery, Jr., Dennis Letang, Leopold Super

Patent number: 6941245Abstract: A method and system for controlling engine temperature by derating torque output of the engine. The method and system operate in cooperation with an electronic control module which is programmable for controlling temperature in the engine by derating maximum engine torque output based on an engine temperature rate of change. This permits the derating to be finely tuned to maximize available torque.Type: GrantFiled: September 3, 2003Date of Patent: September 6, 2005Assignee: Detroit Diesel CorporationInventors: John Edward Longnecker, Leopold Super, Richard Michael Avery, Jr., Brian Lewallen

Patent number: 6925804Abstract: A method for controlling an internal combustion engine having a variable geometry turbocharger (VGT) and an exhaust gas recirculation (EGR) system in the face of sensor failures and mechanical faults includes generating accurate substitute values for use by the engine control logic when EGR and VGT system-related sensors are diagnosed as having failed during operation, and maintaining controlled performance of the VGT system in the face of sensor failures or mechanical faults associated with the EGR or VGT system.Type: GrantFiled: September 29, 2003Date of Patent: August 9, 2005Assignee: Detroit Diesel CorporationInventors: John E. Longnecker, Richard M. Avery, Jr., Leopold Super

Patent number: 6920386Abstract: A method and system for indirectly estimating ambient air temperature. The ambient air temperature is estimated based on filtering a temperature input from a turbocharger air inlet sensor. The filtering includes compensating for engine compartment temperature variations which vary relative to the actual ambient temperature.Type: GrantFiled: September 30, 2003Date of Patent: July 19, 2005Assignee: Detroit Diesel CorporationInventors: Leopold Super, Richard M. Avery, Jr., John E. Longnecker

Patent number: 6904352Abstract: A method for estimating engine torque loss due to a fan. A table of maximum fan torque losses is compiled at a plurality of engine speeds. An engine control unit (ECU) is configured with the table of maximum fan torque losses. A first maximum fan torque loss and a second maximum fan torque loss for an engine speed are retrieved from the table. A maximum fan torque loss for the engine speed is estimated by interpolating between the first maximum fan torque loss and the second maximum fan torque loss. An engine torque loss estimate is calculated by adjusting the maximum fan torque loss based on a set of predetermined fan characteristics.Type: GrantFiled: September 29, 2003Date of Patent: June 7, 2005Assignee: Detroit Diesel CorporationInventors: Jeffery S. Hawkins, Richard M. Avery, Jr., Leopold Super

Patent number: 6886336Abstract: A method for controlling condensation in an engine. A set of signals indicative of an intake manifold temperature, intake manifold pressure, intake air temperature, intake air humidity, engine speed, and exhaust gas mask flow rate is provided. A critical value that indicates that condensation could occur is calculated. The critical value is compared to a predetermined threshold value or range. An exhaust gas recirculation valve is closed if the critical value exceeds the predetermined threshold value or range. The exhaust gas recirculation valve is opened if the predetermined threshold value or range is not exceeded.Type: GrantFiled: September 29, 2003Date of Patent: May 3, 2005Assignee: Detroit Diesel CorporationInventors: Leopold Super, Richard Michael Avery, Jr., John Edward Longnecker
