US Classification:

701104, 12333923, 123352, 701110

Abstract:

An engine control system ( ) and method for improving stability of engine running speed when torque subtractions (TTS) from gross torque change while the engine ( ) is running at a constant speed, such as at low idle speed. Engine speed error data (Nerror) is processed according to one or more control functions ( ) each having gain determined by the torque subtraction data value via function generators ( ) to develop fueling adjustment data (P-FGT, I-FGT, D-FGT) for compensating desired engine fueling (MFDES) for the torque subtraction data (TTS).

Abstract:

A method for servicing a motor vehicle () with an electronic service tool () that is placed in bi-directional data communication with an electrical system in the vehicle. With the vehicle's motor not running, but with electric power being applied to the vehicle's electrical system, tool () is updated by transmitting from the vehicle to the tool, set data containing a current set of vehicle-related parameters stored in the vehicle. With the motor running, the vehicle is serviced with the tool using the set data transmitted to update the tool.

US Classification:

12356812, 12356811, 12356821, 701108, 60278

Abstract:

An EGR control method to prevent condensation within the EGR system uses a temperature sensor signal from an EGR cooler exhaust gas outlet to model or estimate exhaust manifold gas temperature upstream of the cooler. If the estimated exhaust manifold gas temperature falls below a predetermined level, the engine control system closes or partially closes the EGR control valve to stop EGR flow through the cooler and the EGR valve.

International Classification:

US Classification:

12356812, 12356821

Abstract:

This invention relates to a method for protecting an exhaust gas recirculation (EGR) valve from fouling due to hydrocarbon condensation at low EGR cooler outlet exhaust temperatures. In modern internal combustion engines exhaust gas recirculation (EGR) valves provide a means to recirculate exhaust gases into the intake air stream. The EGR valve regulates the flow of exhaust gas entering the stream. The EGR valve can experience fouling due to the condensation of hydrocarbons at low EGR cooler outlet exhaust temperatures. Typically, fouling occurs when the internal combustion engine is operating at relatively low temperatures, namely during low speed and/or low torque operations. The effects of fouling an EGR valve include higher emission levels, reduction in fuel economy, and rough idling.

US Classification:

60286, 422168

Abstract:

Apparatuses described herein relate to a diesel particulate filter for use in a diesel engine exhaust system. The diesel particulate filter comprises a particulate filter having a plurality of filter flow channels configured to remove diesel exhaust particulates from a diesel exhaust stream. The plurality of filter flow channels are disposed for contact with the diesel exhaust stream and are coated with a three-way catalyst coating. The three-way catalyst coating may be configured to assist in soot oxidation during regeneration events as well as for the reduction of NOfrom the exhaust stream. The three-way catalyst coating may replace, or be used in addition to, a three-way catalyst of a diesel oxidation catalyst.

International Classification:

US Classification:

12333924

Abstract:

An electronic engine control for reducing, and ideally eliminating, accumulation of products of incomplete combustion that result from cold ambient conditions acting on the engine and that otherwise might ultimately affect engine operation before the useful life of an engine has elapsed. An idle speed control has a first source providing a signal corresponding to ambient air temperature, a second source providing a signal corresponding to engine coolant temperature, a third source providing a signal indicating that an engine is running substantially in an idle condition, and a processor that processes the signals from the first source, the second source, and the third source to develop an idle speed control signal for controlling engine idle speed by regulating the engine coolant temperature to a defined coolant temperature when the engine is running in an idle condition and the ambient air temperature does not concurrently exceed a defined air temperature. The engine coolant temperature is regulated to substantially 63. degree. C. (145. 4. degree. F. ) when the ambient air temperature does not concurrently exceed substantially 0. degree. C. (32. degree. F).

International Classification:

F02B 37/24
F02M 25/07

Abstract:

A method of setting actuator position of a variable geometry turbine linked to drive a compressor for a compression ignition engine using exhaust gas recirculation. The method includes detecting an engine transient event; determining current mass air flow through the compressor and exhaust temperature; resetting variable geometry turbine position to maximize mass air flow through the compressor; adding the maximum allowable quantity of fuel; determining exhaust temperature increase; adjusting exhaust pressure to allow an increase in mass air flow and exhaust temperature; and returning to the resetting step until a limit is reached.
