摘要： The present invention is an apparatus for controlling the amount of fuel delivered to an engine during operation at cold and warm temperatures using different sets of fuel rate maps designed to compensate fuel quantity signals to optimize engine performance. A switching mechanism based on engine coolant temperature is used to select which set of maps to use. When the engine coolant temperature is below a threshold level, a cold torque map provides a signal representing the duration limit of time that fuel is to be injected. A compensating factor derived from a cold temperature smoke map is used to adjust the cold torque map signal to limit the fuel amount to prevent excess smoke. When the engine coolant temperature is above the threshold, a fuel duration limit signal from a standard temperature torque map is compared to a fuel duration limit signal from a standard temperature smoke map, and the minimum between the two signals is selected for output to the fuel injectors.

摘要： An apparatus controls an electrohydraulic system of a work vehicle. The work vehicle has a engine, at least one fluid circuit having a variable displacement pump driven by the engine, and a plurality of control valves for controllably passing fluid from the variable displacement pump to a plurality of respective work elements. A device produces a signal indicative of a desired velocity of a respective work element. A device senses a load on a work element and producing a signal representative of the actual load in response to the sensed load. A control device receives the desired velocity signal and load signals, and responsively calculates a desired power level for the electrohydraulic system. Responsively, the control device produces an engine speed command signal indicative of an optimum engine speed in response to the desired power level.

摘要： An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passageway, and a reduction catalyst disposed within the exhaust passageway. The exhaust system may also have a first sensor located to generate a first signal indicative of an operational parameter of the reduction catalyst, and a second sensor located to generate a second signal indicative of a performance parameter of the reduction catalyst. The exhaust system may further have an injection device located to inject reductant upstream of the reduction catalyst, and a controller in communication with the combustion engine, the first sensor, the second sensor, and the injection device. The controller may be configured to determine a NOX production of the combustion engine, determine an amount of reductant that should be injected based on the NOX production and the first signal, and adjust the amount based on the second signal.

摘要： The present invention is an apparatus for controlling a variable geometry turbocharger (VGT) in closed loop and open loop modes, and a switching mechanism for determining whether open loop or closed loop control laws should be used. In the closed loop mode, a correction factor, obtained from a pressure correction map based on engine speed and atmospheric pressure, is subtracted from the desired boost pressure to prevent overspeed of the turbocharger at lower atmospheric pressures. The actual boost pressure is then compared to the desired boost pressure after correction to obtain a boost pressure error signal. The boost pressure error signal is used as an input to a proportional integral differential control law that responsively produces a desired VGT vane position. A minimum limit on the desired VGT vane position is based on engine speed and fuel quantity, whereas a maximum allowable vane position may be a predetermined constant or function. A linearization map is used to obtain a VGT current signal that is transmitted to an actuator for moving the vane position.
摘要翻译：本发明是用于控制闭环和开环模式中的可变几何涡轮增压器（VGT）的装置，以及用于确定是否应当使用开环或闭环控制定律的切换机构。在闭环模式中，从期望的增压压力中减去从基于发动机转速和大气压力的压力校正图获得的校正系数，以防止涡轮增压器在较低的大气压下超速。然后将实际增压压力与校正后的期望增压压力进行比较，以获得增压压力误差信号。增压压力误差信号用作响应地产生期望的VGT叶片位置的比例积分微分控制定律的输入。所需VGT叶片位置的最小限制是基于发动机速度和燃料量，而最大允许叶片位置可以是预定的常数或功能。使用线性化图来获得传输到用于移动叶片位置的致动器的VGT电流信号。

摘要： The present invention is an apparatus for controlling exhaust gas recirculation in an internal combustion engine. The apparatus includes an exhaust gas recirculation controller that uses sensed engine operating parameters and the engine operational mode to determine whether to enable or disable the exhaust gas recirculation valve. When the valve is enabled, a closed-loop controller determines the desired amount of exhaust gas to recirculate and the corresponding position of the exhaust gas recirculation valve to introduce the desired amount of exhaust gas into the engine's air intake manifold. The desired valve position is converted to a current signal which is transmitted to an actuator to move the valve. When the valve is disabled, the current signal is set to a value to close the valve to prevent exhaust gas from being circulated in the engine's air intake manifold.
