First Claim
Patent Images
1. A method of measuring reduction of greenhouse gas by idling stop, comprising:
- measuring a first amount of fuel consumed in an engine before the engine of a vehicle, which is in idling state, stops, by a fuel consumption amount measurer;
measuring a second amount of fuel consumed for restarting the engine, which is stopped, by the fuel consumption amount measurer; and
calculating exhaust reduction of greenhouse gas by a greenhouse gas exhaust reduction calculator from idle stop of the vehicle to engine restart, on the basis of the first and second amount of fuel consumed and an engine stop-continued time from the outside.

Abstract
Provided are a method and an apparatus that make is possible to measure the amount of greenhouse gas reduced for the stop time of an engine stopped while a vehicle idles. A first amount of fuel consumed in an engine is measured before the engine of a vehicle idling stops. A second amount of fuel consumed for restarting the engine, which is stopped, by idling of the vehicle is measured. Exhaust reduction of greenhouse gas is calculated from idle stop of the vehicle to engine restart, on the basis of the first and second amount of fuel consumed and an engine stop-continued time from an ECU.
