    摘要： An improved fuel compensation method for a variable cam phase engine which predicts the phase of the cam at the midpoint of valve overlap and uses the predicted cam phase to compensate a base fuel pulse for the corresponding amount of diluent. If the cam phase is in transition to a desired value, the cam phase for purposes of compensation may be predicted based on the desired cam phase, current cam phase and its rate of change; otherwise, the cam phase is predicted based on the current cam phase. In a first interval of cam phase transition characterized by nonlinear change in cam phase, the cam phase is predicted by applying a nonlinear offset to the measured cam phase. In a second interval of cam phase transition characterized by substantially linear variation of cam phase, the cam phase is predicted by linear extrapolation of the measured cam phase, and limited to range bounded by the measured cam phase and the desired cam phase.

    摘要翻译： 一种用于可变凸轮相位发动机的改进的燃料补偿方法，其预测在阀重叠的中点处的凸轮的相位，并且使用预测的凸轮相位来补偿相应量的稀释剂的基本燃料脉冲。 如果凸轮相位转换到期望值，则可以基于期望的凸轮相位，当前凸轮相位及其变化率来预测用于补偿的凸轮相位; 否则，基于当前凸轮相位来预测凸轮相位。 在以凸轮相位非线性变化为特征的凸轮相变的第一区间中，通过对所测量的凸轮相位施加非线性偏移来预测凸轮相位。 在以凸轮相位的基本上线性变化为特征的凸轮相位转变的第二区间中，凸轮相位通过所测量的凸轮相位的线性外推来预测，并且被限定在由所测量的凸轮相位和期望的凸轮相位限定的范围内。

    摘要： A method and apparatus for controlling the amount of fuel used in combustion during open-loop run mode of a internal combustion engine. A lookup table calibrated to a fuel with a low driveability index is used to make a fueling decision for open-loop run mode. Then, at least one of the following indicators of fuel problems is monitored: the engine misfire detection system, the engine speed and the manifold absolute pressure. If any of these indicators detect a problem with the amount of fuel the engine is receiving, a fuel increase is calculated and implemented in one or more steps. A problem is indicated if an engine misfire is detected, the engine speed drops below a predetermined threshold value, or the manifold absolute pressure rises above a predetermined threshold value. The fuel increase is limited by a calculation based upon a fuel with a high driveability index.

    摘要： A diesel oxidation catalyst (DOC) testing system includes a DOC that is located in an exhaust system of a vehicle. A control module verifies proper operation of the DOC during a post-fuel injection process in an engine of the vehicle. The control module computes a predicted temperature of exhaust gases at an output of the DOC that corresponds with proper operation of the DOC during the post-fuel injection process, determines an actual temperature of the exhaust gases during the post-fuel injection process, and activates an alarm indicator when a difference between the predicted temperature and the actual temperature is greater than a first predetermined value. A first temperature sensor is located downstream from the DOC in the exhaust system. The first temperature sensor communicates with the control module, generates the actual temperature, and transmits the actual temperature to the control module.

    摘要： A reed valve for a passage defined by an inner surface in an engine comprises a cage mounted across the passage. The cage has a cage port, an upstream side and a downstream side. The read valve includes a flexible petal having a fixed portion connected to the cage enabling the petal to flex away from the cage in a cantilevered manner. The petal overlies the cage port to allow fluid flow therethrough from the upstream side to the downstream side by flexing away from the cage, and to obstruct fluid back-flow in the reverse direction by seating against the cage. The read valve further comprises an inflatable member adjoining a portion of the petal which flexes away from the cage. The petal is sandwiched between the inflatable member and cage so that inflation of the inflatable member obstructs the flexing of the petal away from the cage to reduce the effective length of the petal.
