自動車의 走行모드가 燃料消費率에 미치는 影響에 관한 計算的 연구

Abstract

The era of high-priced oil has opened its stage as they went through oil crises twice in 1970s. Although the oil price has been stabilized since 1980s consecutive exchange rate increase and rapid increase of the oil price have increased the burden on the consumers who use oil energies.

Also, the increase of vehicles are becoming the major factors for the global environment contamination, and the exhaust regulations restricted to hydrocarbon, nitrogen oxide, carbon monoxide are expanded to cover carbon dioxide, as related to the recent day-to-day global warming. As the amount of CO₂ increases as the fossil fuels used for the vehicles are combusted ideally, the ways of reducing the CO₂ itself using combustion technology or post-processing technology are not being presented. The only way is to reduce the use of fuels, and for this reason many researches are in progress.

Vehicles are used by many drivers who have different driving habits, and the driving modes are also different accordingly.

Selecting the driving mode properly and driving in efficient areas can reduce the fuel consumption dramatically. Also, vehicles consume the height energy and the motion energy with the braking energy when they go down a hill or when they brake. They have Fuel cut-off capability in order to recall this energy, and the driving utilizing this can further save the fuel.

This paper intends to make a calculating program that can calculate the fuel consumption rate in the general driving mode, and using this compare the fuel consumption rates for the fast accelerating mode, the normal mode and the slow accelerating mode, and after the collective examination will present the best driving mode when driving on flat lands.

As the result, We would be predict the best running mode and save 24% fuel oil as well.
