Abstract
A computing unit of an analysis device calculates a weight of fuel consumed by an engine based on the weight of intake air and air fuel ratio of an engine of a vehicle to be analyzed detected by an air flow meter and an air-fuel ratio sensor , and computes a fuel consumption rate based thereon and the running distance. The computation of fuel consumption rate does not require an injection pulse signal, so the fuel consumption rate can be precisely computed even for a vehicle which does not have an injection pulse signal such as a non-EGI vehicle or a diesel engine vehicle.
