摘要： A fluid pressure near a filter (103) is measured and compared (307) to a predetermined value that is based on one or more engine operating parameters. When the measured fluid pressure deviates enough from the predetermined value by an established amount, an indication of the deviation may be provided to notify of a potential problem with the filter (103), such as obstruction, restriction, or some form of clogging.

摘要： Engine speed data N and engine fueling data MFDES are processed by a strategy (22) that multiplies (28) fueling transient data MFDES TRANSIENT and speed-based modifier data EGR_N_TRANS_MULT to develop speed-based fueling transient data. The speed-based fueling transient data is then processed according to a function (32) that correlates values of a fueling transient modifier with values of speed-based fueling transient data to develop exhaust gas recirculation modifier data. The exhaust gas recirculation modifier data and basic exhaust gas recirculation data are multiplied (34) to develop modified exhaust gas recirculation data, and exhaust gas is recirculated in accordance with the modified exhaust gas recirculation data. Using engine speed as a determinant of the extent to which the basic EGR rate should be modified during a fueling transient enables better control over certain exhaust emissions over certain speed ranges.

摘要： A PI control strategy controls engine speed to an engine speed set-point. A proportional map (36) is populated with data values to be used in calculating the P component of the strategy. An integral map (38) is populated with data values to be used in calculating the I component. Each data value in the maps is correlated with a speed data value representing engine speed (N) and a speed error data value representing the difference between engine speed and engine speed set-point (N_DIF_MAX_LIM). Values for proportional and integral components are selected from the respective maps by processing current engine speed data and current engine speed error data. The strategy uses the values from the maps for controlling engine speed to the speed set-point. Data values from other maps (20 and 24; or 22 and 26) modify the selected values from the proportional and integral maps (36, 38) for transmission type, transmission gear, and engine temperature.

摘要： An internal combustion engine that propels a vehicle has a fuel injection system for injecting fuel into engine cylinders at desired injection control pressure. A control system controls activation and de-activation of a hydraulic actuator for an engine brake. A processor processes data to develop data for desired injection control pressure. Transitional injection control pressure data is used as desired injection control pressure during a transition time interval that commences with de-activation of the engine brake caused by the relief of pressure of the control fluid for allowing resumption of positive power flow from the engine for propelling the vehicle and that ends after the processor has determined the existence of a predetermined correlation between the transitional injection control pressure data and data indicating pressure of the control fluid.

摘要： An engine (10) having a control system (24) that executes a control strategy (44) for limiting engine fueling upon deactivation of an engine retarder. Upon deactivation of the retarder, the strategy immediately shuts off fueling by setting the maximum fueling limit MFLMX to zero via setting of a latch function (42). Fueling continues to be shut off so long as the difference between a desired pressure for the hydraulic fluid used to force fuel into the engine combustion chambers and actual pressure of the hydraulic fluid (ICP—ERR) equals or exceeds a value (ICP—VRE—ERR) from a map (48) correlated both with the speed (N) at which the engine is running and with governed engine fueling (MFGOV) appropriate for the load on the engine at the engine running speed. Once that difference ceases to equal or exceed a value from the map (48), the latch function is reset, and the limit value for fueling provided by the strategy increases withtime according to a map (54).

摘要： A method provides for transferring back-up data between on-board electronic modules of a vehicle. The presence of default parameters is sensed at a first electronic module during a running of the vehicle engine for an engine cycle. The current engine cycle accumulation register data is stored for the engine cycle in the first electronic module. A parameter and accumulation register data recovery routine is run wherein parameters and accumulation register data for the first electronic module are recovered from memory in the second electronic module on the vehicle and restored in the memory of the first electronic module. The information is transferred using SAE J1939 protocol. The first electronic module can be an engine control unit and the second electronic module can be a body controller. During a parameter and data back-up routine periodically run, the first electronic module stores current parameters and accumulation register data into memory of the second electronic module that will serve as back-up parameter and accumulation register data storage in the event the first module loses such parameters and accumulation register data.
