Appl. No.:

10/692948

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02D 2300

US Classification:

701102, 60612

Abstract:

A control system ( ) for controlling the extent to which a valve ( ) selectively by-passes exhaust flow around one of two turbines ( T, T) in an engine exhaust system ( ). A desired set-point (TCBC_DES) and the actual set-point of operation of the valve are used to develop a set-point error for closed-loop control of the actual set-point. A data value for closed-loop gain is selected from a schedule ( ) based on engine speed and fueling. The selected data value of closed-loop gain and the set-point error data value are used to create a data value for a closed-loop output (TCBC_DTY_PIF) that is used to create a data value for a final output for forcing the actual set-point to the desired set-point.

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02D 4114

US Classification:

701104, 123674

Abstract:

A schedule () correlates data values of closed-loop gain (KP, KI) with engine temperature values (EOT) and engine speed values (N). A control strategy develops a data value (ICPC_DES) representing desired injector control pressure (ICP) set-point, processes ICPC_DES and a data value (ICP_MPA) representing actual ICP to develop ICP error data value (ICP_ERR) for closed-loop P-I control () of actual ICP. Data values for closed-loop proportional and integral gains are obtained from the schedule based on measured engine temperature and measured engine speed. ICP become less subject to undesirable fluctuations that might otherwise change fuel injection quantity in ways detrimental to attainment of desired tailpipe emission objectives.

Rogelio Rodriguez - Plainfield IL, US

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02D041/22

US Classification:

701114, 700 79

Abstract:

Fault monitor () for error input (ICPCERR) to closed-loop control () of an engine function, such as a control pressure for a fuel system (). Error input is derived from the desired and actual data values for the function. An integration function integrates the absolute value of the input data value () during a time interval defined by a timing function () to provide an integrated data value. A comparison function () compares the integrated data value and a data value ICPCOBDERR defining a fault indication.

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02M025/07

US Classification:

701108, 12356821

Abstract:

Desired engine fueling data FQLMFDTQL is processed by a derivative variable time function () embodied in an algorithm to develop a data value EGRMFDDER representing the time derivative of desired fueling. The algorithm comprises certain selectable parameters (EGRDTS, EGRMFDKF, EGRMFDKD). An iteration of the algorithm includes processing FQLMFDTQL according to a first function (A) to yield a first data value and according to a second function (B) to yield a second data value. A third function (C) subtracts the second data value from the first to yield a data value for the time derivative that forms one input to a map (). A second input to the map is a data value for mass airflow (MAFGMS). The map provides data for calculating the set point of an EGR valve (). The invention provides improved control of EGR during fueling transients.

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02M037/04

US Classification:

123502, 123446

Abstract:

An internal combustion engine fuel system applies injection control pressure to fuel injectors () to force fuel into combustion chambers (). A processor of a control system () develops data values for injection control pressure set-point (ICPCT13) representing desired injection control pressure and evaluates () the injection control pressure set-point data values for compliance with an allowable dynamic range defined by a data value for a minimum dynamic limit correlated with engine speed (N) from a function generator () and a data value for a maximum dynamic limit correlated with engine temperature (EOT) from a function generator (). The processor limits the data value of desired injection control pressure that is subsequently processed to control injection control pressure applied by the fuel system to the fuel injectors to the allowable dynamic range.

International Classification:

F02P 19/02

US Classification:

1231796, 123145 A

Abstract:

A motor vehicle engine () has a glow plug system () for aiding combustion of fuel in combustion chambers of the engine when the engine is cold and an ignition switch () is operated to crank the engine. A first circuit signals the cold start aid to commence operation of the cold start aid in anticipation of engine starting. A second circuit indicates a fault in the cold start aid. A third circuit, that includes a warning signal device (), activates the warning signal device to inform a driver of the vehicle of the indicated fault upon the first circuit having signaled the cold start aid to commence operation and the second circuit having indicated a fault in the cold start aid.

International Classification:

B60K 41/04

US Classification:

701102, 701 51, 701 54, 606052

Abstract:

Torque being produced by a turbocharged internal combustion engine () during acceleration under load is calculated by processing () a value for actual boost MAP and a value MAP_NOMINAL selected from a map () that contains data values for boost that would prevail during steady state engine operation at a respective speed with the engine developing a respective torque. The selection is made using engine speed N and estimated torque TQI_SP that possesses some inaccuracy due to some disparity between the data value for actual boost and the data value selected from the map. The selection yields a boost disparity value that is used along with the estimated torque to select from a torque map () a value for calculated torque that provides a better correlation with actual torque than does the estimated torque during acceleration.

US Classification:

Abstract:

A first fuel value (FL_Signal) indicative of the quantity of fuel presently in a fuel tank () and a second fuel value (FL_LOW_THLD) representing a quantity of fuel in the tank at which a maximum Injection Control Pressure (ICP) limit should be changed are processed by a processor (). When the result of the processing discloses that the second fuel value is less than the first fuel value, the maximum ICP limit is reduced from a greater value (ICPC_NORMAL_LMX) to a lesser value (ICPC_FL_LMX).
