Method for determining fuel consumption of an internal combustion engine

A method can be used for determining fuel consumption of an internal combustion engine of a vehicle, in real time. The method includes determining a fuel injection quantity of the internal combustionengine based on an oxygen concentration signal from an oxygen sensor and a MAF signal from a mass airflow (MAF) sensor. The MAF sensor is coupled to the intake line and is configured to measure and monitor the mass flow rate of intake air flowing through the intake line. The method further includes determining, via an engine control module (ECM), an instantaneous fuel flow of the internal combustion engine based on the fuel injection quantity. The method further includes communicating, via the ECM, the instantaneous fuel flow to a body control module (BCM) and determining, via the BCM, an average fuel economy of the internal combustion engine based on the fuel flow. 种方法可被用于确定车辆的内燃机的实时燃料消耗。该方法包括基于来自氧气传感器的氧气浓度信号和来自空气质量流量(MAF)传感器的MAF信号来确定该内燃机的燃料喷射量。该MAF传感器联接至进气管线，并且被配置成用于测量和监控流过该进气管线的进入空气的质量流率。该方法还包括经由发动机控制模块(ECM)基于该
