The Effect of Nitrogen Gas in Tire on Vehicle Fuel Consumption

Concerning the increase of fossil fuel consumption, air pollution, and the cost of fossil fuels, doing some measures in order to decrease vehicle fuel consumption is inevitable. The purpose of the paper is to examine the effect of nitrogen gas in tire on vehicle fuel consumption. First, some conditions were introduced as criterion conditions and the quantity of fuel consumption was measured. Then, by changing the inflation pressure and the type of the gas inside the tire, fuel consumption of the intended car was measured by detecting engine RPM and the time injection of injectors. Results of the research revealed that the use of nitrogen gas inside the tire and increasing the inflation pressure can considerably decrease vehicle fuel consumption.
