摘要:
Diesel fuel consumption is calculated in real-time in an vehicle diagnostic monitor using standard OBDII reported parameters and publicly available engine characteristics. Also, fuel consumption in vehicles that maintain a constant air-fuel ratio is calculated by analyzing the subject engine as an air pump and reading publicly available OBDII diagnostic data to estimate the instantaneous airflow through the engine without the need of MAF sensor data.
