First Claim
Patent Images
1. An exhaust gas measuring device comprising:
- an exhaust gas concentration measuring part that measures concentration of a component related to a carbon compound in exhaust gas discharged from an internal combustion engine;
wherein a discharged amount of the component related to the carbon compound is calculated based on the measured concentration of the component related to the carbon compound and a flow rate of the exhaust gas, and a workload of the internal combustion engine is calculated based on the discharged amount; and
wherein the component related to the carbon compound is a plurality of components including at least CO, CO2 and a hydrocarbon class.

Abstract
With the exhaust gas measuring device and the exhaust gas measuring method, the workload of the internal combustion engine is calculated based on a discharged amount of a component related to a carbon compound such as CO, CO2 and THC in the exhaust gas discharged from the internal combustion engine. As a result, the workload of the internal combustion engine can be calculated easily without using torque data of the ECU and the mass of each component in the exhaust gas discharged from the internal combustion engine per unit workload can be calculated.
