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： 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.
