Abstract
To achieve high-accuracy measurements of fuel consumption in testing on natural gas vehicles, a method for measuring the absolute value of fuel consumption by the gravimetric method using certificated reference weights and an electric platform scale has been developed. By performing a flow-meter test and a chassis dynamometer test using the gravimetric method, the measurement accuracy of the value of fuel flow rate and fuel consumption obtained by the fuel flow meters, carbon balance method, and air-to-fuel ratio method was evaluated. As a result, a highly accurate method for measuring fuel consumption in chassis dynamometer tests has been confirmed.
