Analisa Pengaruh Kecepatan dan Posisi Gigi terhadap Konsumsi Bahan Bakar dan Emisi Gas Buang CO2 pada Mobil Honda CRV dan Toyota Limo sebagai Pendukung Program Smart Driving

Abstract

Fuel oil is generally used as an energy source. The most absorbing sector is transportation, especially road transport. Meanwhile road transport also produce huge amount of pollutant like CO2 which is lead to global warming. Smart Driving is a program to decrease fuel consumption with easy, safe, and comfort method. It is aim to change driving behavior of driver so they can drive at the optimum use of fuel and saving nature together. One way is using high gear position and controlling in vehicle speed. The experiment test runs to find the correlation between speed and gear position with fuel consumption and emission levels. It was taking placed at Efficiency and Energy Conservation Laboratory, Mechanical Engineering of Diponegoro University. This experiment using a Honda CRV and Toyota Limo as objects, and dynamometer to measure power. The other instruments is gas analyzer and engine scanner which using to a few parameters such as engine speed, vehicle speed, fuel consumption, etc. Both can be connecting to computer so we can see the parameters at real time or playback. The other experiment is road test, in this test we carried the car on the road to see the actual condition and we using additional tool like GPS trip recorder to find out the actual condition of road, where they straight, curved, or incline. The results showed that correlation between vehicle speed on fuel consumption and CO2 level is parabolic with cubic equation at the both cars for every gear. If we ignore gears position it has high error value, until 50% which make gears position is essential part. Gear positions also have an effect to CO2 level. The higher the gear will make the lower CO2 level. This result concluding that between fuel consumption and CO2 level have linearity related.
