  • Patent number: 7055496
    Abstract: 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.

  • Patent number: 7058502
    Abstract: A motor vehicle (20) has a diesel engine (22) and one or more sources (30, 36) providing data relevant to operations of the vehicle that are external to the engine but potentially influential on fueling of the engine. An engine control system (24) processes data according to an all-speed governing strategy for controlling engine fueling to develop all-speed governed fueling data (MFGOV) that sets engine fueling when a data input to the engine control system from the one or more sources discloses no need to influence engine fueling. When the data input from such one or more sources discloses a need to influence engine fueling, that data input causes engine fueling to be set by a strategy other than the all-speed governing strategy, a torque speed control strategy (54) in particular.

  • Patent number: 7021276
    Abstract: A compression ignition engine (20) has a control system (26) for processing data, one or more combustion chambers (22), and fuel injectors (24) for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of certain data, such as engine speed and engine load, to select one of two fueling modes (HCCI, HCCI-CD) for operating the engine. When the result of the processing selects the HCCI mode, the engine is fueled to cause homogeneous-charge compression-ignition (HCCI) combustion within the combustion chambers. When the result of the processing selects the HCCI-CD mode, the engine is fueled to create a substantially homogeneous combustible charge within each combustion chamber that is compressed to auto-ignition, and after auto-ignition, more fuel is injected to provide additional combustion in the manner of the conventional diesel combustion.

  • Patent number: 7017561
    Abstract: An engine (10) utilizes “regular EGR cooling” when operating in HCCI mode at loads within a low load range (56, 58, 60) and “enhanced EGR cooling” that allows the engine to continue to operate in HCCI mode when engine load increases beyond loads in the low load range (64, 66, 68). When engine load increases further to a point where it enters a high load range, the combustion mode changes over to conventional diesel combustion, and exhaust gas recirculation reverts to “regular EGR cooling” (70, 72, 74).

  • Patent number: 7013212
    Abstract: A compression ignition engine (10) has a control system (24) for processing data, one or more cylinders (16), a fueling system (18), and a variable valve actuation mechanism (20). Control system (24) develops both fueling data for fueling the engine and timing data representing time during the engine cycle for intake valve closure to a cylinder that will endow the cylinder with an effective compression ratio (ECR) appropriate to current engine operation for causing auto-ignition to occur near or at top dead center in the engine cycle. During a compression upstroke, the cylinder is fueled according to the fueling data and intake valve closure for the cylinder is performed according to the timing data. This creates an air-fuel mixture that is increasingly compressed to the point of auto-ignition near or at top dead center.

  • Patent number: 6993428
    Abstract: An internal combustion engine has cylinders within which combustion occurs and an exhaust system through which products of combustion are exhausted from the cylinders. A temperature sensor and an electric heater are disposed in temperature sensing relation to the exhaust gas flow. A processor develops temperature data obtained from the temperature sensor, and power data representing power required to heat the electric heater to a temperature in excess of temperature of exhaust gas flow past the heater. The processor processes the temperature data, the power data, and data representing mass flow through the engine upstream of the temperature sensor and heater according to an algorithm for yielding data representing difference between mass flow of exhaust gas past the temperature sensor and heater and mass flow upstream of the temperature sensor and heater. The measurement may then be used to measure leakage from the exhaust system by subtracting it from flow measurement in a different location.

  • Patent number: 6978604
    Abstract: A control system (FIG. 4) for controlling regeneration of a DPF comprises a favorable-condition-based control section (52), a regular control section (54), and a regeneration termination control section (56). Section (54) initiates regeneration when the actual soot loading of the DPF becomes sufficiently large to mandate initiation of regeneration. Section (52) initiates regeneration when the actual soot loading reaches an amount less than the amount at which section (54) mandates regeneration, provided that selected engine operating conditions disclose conditions favorable for regeneration. Section (56) terminates regeneration when soot loading is reduced to some minimum amount or when conditions for continuing regeneration become unfavorable. By burning trapped soot during favorable conditions, the mandatory regeneration is postponed. This can lower the average amount of trapped soot in the CDPF, thereby lowering the average back-pressure on the engine.
