DEVICE FOR CALCULATING AMOUNT OF REDUCED FUEL CONSUMPTION, AND PROGRAM FOR DISPLAYING CALCULATION, AS WELL AS DEVICE FOR CALCULATING AMOUNT OF REDUCED CO2 EXHAUST, AND PROGRAM FOR DISPLAYING CALCULATION

摘要

PROBLEM TO BE SOLVED: To provide a fuel consumption reduction amount calculation device, a fuel consumption reduction amount calculation and display program, a carbon dioxide emission reduction amount calculation device, and a carbon dioxide emission reduction amount calculation and display program, that digitize the fuel consumption reduction amounts or CO₂ emission reduction amounts of a vehicle or a drier or the other heating appliances.;SOLUTION: A fuel consumption reduction amount calculation device 10 inputs base line data 14 and 16 of a vehicle before mounting a combustion improvement device and project data 18 and 20 of the vehicle after mounting the combustion improvement device, and displays a value calculated by subtracting annual fuel consumption amount taken from project data from a value calculated by dividing annual travel distance taken from the project data by the fuel consumption rate taken from the base line data. Also, a carbon dioxide emission reduction amount calculation device 34 displays a value calculated by subtracting an emission amount that is calculated by multiplying an emission coefficient by the annual fuel consumption amount taken from project data from the emission amount calculated by multiplying the annual fuel consumption amount taken from the project data by the annual travel distance taken from the project data divided by the fuel consumption rate taken from the base line data.
