Abstract: A control system for vehicle engines includes an automatic start and stop idling feature. The control starts engine running in response to detected engine conditions such as oil temperature of battery voltage in at least one mode, and in response to a thermostatic mode by a comfort thermostat in a cabin in at least a thermostat mode of operation. The thermostat mode operation is modified to terminate responses to inputs from the thermostat after an extended period for operation matches programmed threshold representative of no occupation in the area with the thermostat.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method for controlling at least one engine cooling fan for a compression ignition internal combustion, the method includes turning on the at least one cooling fan when an intake manifold air temperature is equal to or greater than a predetermined turn-on threshold temperature for a predetermined turn-on time, and turning off the at least one cooling fan when the intake manifold air temperature is equal to or less than a predetermined turn-off threshold temperature for a predetermined turn-off time, wherein the predetermined turn-on threshold temperature is greater than the predetermined turn-off threshold temperature.

Abstract: 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.

Abstract: Silicone organic blends for use as lubricating oils, hydraulic fluids, dielectric fluids, coolants, and in compressor or vacuum pump applications, have improved viscosity stability when the polydispersity of the silicone fluids used in these blends, i.e., their molecular weight distribution (Mw/Mn), exceeds 1.5. The viscosity rise of the silicone organic blend is less than one centistoke (mm2/s) when aged 14 days in an oven at 100° C., compared to viscosity rises of about 1.3 to over 3.5 centistokes (mm2/s) for commercial silicone organic blends using silicone fluids with polydispersity less than 1.5.
