Abstract
Methods, software codes, and devices for determining an emission flow rate of one or more CO2 equivalent gases from an exhaust system of an internal combustion engine of a vehicle and a method of determining a vehicle efficiency factor of the vehicle are provided. The vehicle efficiency factor is compared in real time to the corresponding point on a vehicle efficiency map based on at least one of current vehicle conditions, driving conditions, environmental conditions, and energy flow visualization data to derive a driver efficiency factor.
Claims17
A method for determining an emission flow rate of at least one CO2 equivalent gas from an exhaust system of an internal combustion engine of a vehicle, the engine powered by a fuel and the exhaust system comprising a catalytic converter, the method comprising:
- collecting fuel data for the fuel;
- generating an emissions factor for the at least one CO2 equivalent gas;
- collecting engine data for the engine;
- collecting catalyst data for a catalyst;
- generating a combustion factor for the at least one CO2 equivalent gas;
- and
- generating the emission flow rate for the at least one CO2 equivalent gas based on a flow rate of the fuel to the engine and the respective emissions factor and the combustion factor.
