Exhaust gas from earth-moving machinery is regulated using chamber tests for the engines installed in the machines. On theother hand, in line with the trends in on-road vehicles, measurements on exhaust gas emitted from working earth-moving machineryhave been reported in Japan and other countries. The reliability of such measured values must be determined in order todiscuss the magnitude, and measurement methods must be simplified in order to obtain much data on various machines in thefuture. This paper proposes using CO2-based emission rate (g/kg-CO2) to evaluate the amount of gas emissions, and choosing‘Idling’ and ‘Grading (simulated work)’ when measuring working machines in order to improve the reliability of measured valuesand to simplify the measurement. It is predicted that measurement of 5 minutes of ‘Idling’ performed three times, and 60 cyclesof ‘Grading (simulated work)’ performed three times by different machine operators can control the precision of estimated randomerrors of the measured NOx values to no more than 10% with 95% reliability.
