Abstract:
The prototype of the eco-car driving practice kit was designed and developed for simulating eco-car driving in order to compare the fuel consumption rates between driving on the tester and driving on the real field. The test was divided into three stages. In Stage 1, the eco-car was tested by driving at an average speed of 30 km/h with adjustments to increase or decrease the downforce of the drag force generated at the wheels at 0, 5, 10, 15, and 20 newtons. The average fuel-consumption rate was calculated, and the result was compared with the results from the Honda Eco Mileage Challenge No. 25/2565, which found the fuel-consumption rate at 256.75 km/L. The test result showed that the downforce of the drag force generating set was close to the result of the Honda Eco Mileage Challenge, i.e., 6.84 newtons. In Stage 2, the eco-car was driven at different speeds, i.e., 50, 55, and 60 km/h. The test results showed that at 60 km/h, the car fuel consumption was the best. In Stage 3, the data from the above driving tests were compared to find the tendency of the average fuel consumption rates at the 18-km distance according to the rules of the competition. The test results showed that the average fuel consumption rate was 51.48 grams (265.80 km/L). Therefore, in terms of future improvement and development, the researcher can predict the fuel consumption rate before the real competition to find the best point of improvement for the next competition.
