摘要： A system and method for monitoring and controlling an engine based on an engine fluid pressure include sensing an engine fluid pressure, determining a current value for an engine operating parameter, determining whether the engine fluid pressure has crossed a first threshold corresponding to the current value of the engine operating parameter, determining whether the engine fluid pressure has crossed a second threshold corresponding to the current value of the engine operating parameter, generating a warning signal when the fluid pressure has crossed the first threshold but has not crossed the second threshold, and generating a shutdown signal when the fluid pressure has crossed the second threshold. In one embodiment, the second threshold is determined based on the first threshold by applying a constant offset value.

摘要： A system and method for controlling fuel delivery from a fuel injector includes determining engine speed, determining a proposed pilot pulse width time based on engine speed, determining injection pressure, determining a proposed first quantity of fuel to be delivered by the fuel injector based on the proposed pilot pulse width time and injection pressure and determining a desired engine torque output. A desired total quantity of fuel to be delivered by the fuel injector is determined based on the desired engine torque output and engine speed. The proposed first quantity of fuel is compared with the desired total quantity of fuel. A desired first quantity of fuel to be delivered by the fuel injector is determined based on the desired engine torque output and engine speed if the proposed first quantity of fuel is greater than the desired total quantity of fuel. A desired pilot pulse width time is determined based on the desired first quantity of fuel and the injection pressure. A desired second quantity of fuel to be delivered by the fuel injector is determined by subtracting the proposed first quantity of fuel from the desired total quantity of fuel if the proposed first quantity of fuel is less than or equal to the desired first quantity of fuel. A main pulse width time is determined based on the desired second quantity of fuel and the injection pressure.

摘要： A method for controlling a compression-ignition internal combustion engine which provides delivery of multiple fuel injection pulses per cylinder firing with precision of pulse quantities, separation, and timing adequate for transition between split and single injection at any speed and load, without disturbing the primary engine governor. The method compensates for variable operating conditions such as supply voltage, injection pressure, injection pulse separation, and injector actuation latency or rise-time.

摘要： An exhaust gas treatment system for an internal combustion engine comprises an exhaust gas conduit configured to receive and to deliver exhaust gas to a downstream exhaust treatment device. An injector bay extends outwardly from the exhaust gas conduit upstream of the exhaust treatment device and an exhaust fluid injector mounts through an opening in the injector bay and is in fluid communication with the exhaust gas conduit and oriented in an upstream direction to deliver an exhaust fluid to the exhaust gas in the upstream direction. An exhaust flow baffle extends outwardly from the injector bay and into the exhaust gas in an upstream direction. The exhaust flow baffle is located upstream of the exhaust fluid injector and is configured to define a turbulent, low pressure velocity field downstream thereof and proximate to the exhaust fluid injector.

摘要： An engine controller and computer readable storage medium for detecting cold engine operation include determining at least two fluid temperatures and providing an output signal based on the at least two temperatures. Preferably, an engine coolant temperature, an intercooler temperature, and an engine air temperature are determined via appropriate temperature sensors. In one embodiment, the cold engine output signal is activated or asserted if any one of the at least two fluid temperatures is below a corresponding temperature threshold. The cold engine output signal is deactivated when all of the fluid temperatures are above corresponding temperature thresholds (plus hysteresis where applicable). An optional user-selectable parameter provides for actuation of the cold engine output only during idle. The cold engine output signal may be used to control various accessories including coolant heating systems, shutters, or the like. Additional parasitic loads or an exhaust brake may be actuated to increase combustion temperatures by increasing engine load to reduce or eliminate white smoke.
