摘要： A system for controlling fueling of an internal combustion engine based upon vehicle position includes a receiver associated with the vehicle that is capable of receiving position and altitude information. The vehicle includes a control computer that delivers control signals to an engine fueling system, as well as to a turbocharger control system. The control computer includes a module that receives the altitude information and uses that information to evaluate changes in ambient air pressure that might detrimentally affect turbocharger speed. In one embodiment, the control computer reduces the fueling signal to reduce engine speed in relation to a decrease in ambient air pressure accompanying an increase in vehicle elevation. In another embodiment, the control computer uses the highly accurate altitude information together with engine speed information provides signals to the turbocharger control system.

摘要： A system and method in which the exhaust manifold pressure is measured by a single gauge-type pressure sensor positioned in the exhaust manifold to detect misfires in all cylinders of an internal combustion engine. The pressure sensor detects the exhaust manifold pressure and feeds a signal to a microcomputer via an analog-to-digital converter. A data processing device monitors the pressure waveform created by the data from the sensor to determine if a full or partial misfire occurs. If a cylinder suffers from a partial or complete misfire, the strength of the pressure pulse for that cylinder will be reduced, thus, allowing the data processing device to identify the misfire. The data processing device may determine a misfire by computing an average peak pressure for each combustion cycle, a pressure threshold as a function of engine speed and fuel consumption rate, and a minimum pressure value based on the difference between the average peak pressure and the pressure threshold. The data processing device may alternatively determine a misfire by first computing a coefficient of variation between an observed pressure pulse and the average peak pressure and then comparing the coefficient of variation with a pressure threshold to determine if at least a partial misfire has occurred.
摘要翻译：一种系统和方法，其中排气歧管压力由位于排气歧管中的单个量规式压力传感器测量，以检测内燃机的所有气缸中的失火。压力传感器检测排气歧管压力，并通过模数转换器将信号馈送到微型计算机。数据处理装置监视由传感器的数据产生的压力波形，以确定是否发生全部或部分失火。如果气缸遭受部分或完全失火，则该气缸的压力脉冲的强度将会降低，从而允许数据处理设备识别失火。数据处理装置可以通过计算每个燃烧循环的平均峰值压力，作为发动机转速和燃料消耗率的函数的压力阈值以及基于平均峰值压力和压力之间的差的最小压力值来确定失火阈。备选地，数据处理装置可以通过首先计算观察到的压力脉冲和平均峰值压力之间的变化系数，然后将变化系数与压力阈值进行比较来确定失火，以确定是否发生了至少部分失火。
