Abstract
An instrument that directly measures a flow rate and air-fuel ratio of exhaust gas, and from the flow rate and air-fuel ratio of the exhaust gas, calculates fuel consumption measures the fuel consumption at high response speed and with high accuracy. The instrument is provided with: an ultrasonic flowmeterthat measures a flow rate QEX of exhaust gas flowing through an exhaust gas flow path R; and an arithmetic unitthat calculates fuel consumption Fe of an engine with use of the exhaust gas flow rate QEX obtained by the ultrasonic flowmeterand an air-fuel ratio AFR obtained by an air-fuel ratio sensorthat measures the air-fuel ratio AFR of the exhaust gas flowing through the exhaust gas flow path R.
