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

Abstract

The transportation sector is the most fuel consumer than the other sectors. This sector also be an essence soil such as NOx, CO, CO2 and HC which be a motive of global warming. There is a method to drive more efficient, environmental friendly, safe, and comfortable to reduce the use of fuel from this sector, especially for road transportation, called “Smart Driving”. To support this method, there are conducted the test about the effect of vehicle speed and gear position to fuel consumption and exhaust emission. Fuel consumption and exhaust emission test are conducted at the Laboratory of Conservation and Energy Efficiency Department of Mechanical Engineering of Diponegoro University and on the highway. The Test using Honda Jazz 2010 and Toyota Kijang Innova 2008 manual transmission with gasoline fueled. This test are to determine the correlation between speed and gear position to fuel consumption and CO2 emissions, and to find out the optimum speed on each gear. In addition, this test also intended to identify the correlation between fuel consumption and CO2 emissions and to get the equations of fuel consumption and CO2 emissions that can be used as the basis for the development of driving simulator. The test results showed that the fuel consumption and emissions will reach high value in low gear position while in high gear its value is lower. The relationship between speed to fuel consumption and CO2 emission shape parabola chart like the letter U and has the optimum value at different speed in each gear position. The test results obtained several equations of fuel consumption and CO2 emissions at each gear position, but these can’t be merged because it has an error rate which reaches more than 30%. The test results also showed a linear relationship between fuel consumption and CO2 emissions.
