‍Consideration of Pollution and Fuel Consumption in Vehicles Fuelled with “MTBE – Gasoline Blends”

Abstract

Three types of vehicles, Pride, Peugeot 405 GLX and Paykan were tested from the Point of view of exhaust emissions (CO, HC, NOx) and fuel consumption, on chassis dynamometer running European Standard driving cycle with three kinds of fuels, MTBE free Unleaded Regular Gasoline (URG) as base fuel and 10 and 15 volume percent MTBE –Gasoline blends as comparable Fuels.
Utilizing MTBE blended fuels in Pride had relatively positive effects due to CO (15-22%) and HC (2-10%) emissions reduction in this vehicle and the amount of NOx (5-20%) increased. Measured fuel consumption of this vehicle in all situations of tests (running standard driving cycle and different constant speeds running) with MTBE contained fuels showed little increase (1-3%) compared to URG.Fuelling of Peugeot 405 GLX with 10 and 15 volume percent MTBE –Gasoline blends resulted in considerable reduction of CO (29%) and HC(18-20%) compared to the use of URG and the amount of  NOx(8-15%)  increased.Fuel consumption in this vehicle with MTBE blended fuels also slightly increased compared to URG.Tests done in Paykan like two before mentioned vehicles, resulted in CO(6.5-9.5) and HC    (5-13%) reduction, NOx(7-11%) increase and slight increase of fuel consumption(1-3%).
