Abstract

The present study investigated the impact of fuel kind on the emitted emissions at the idling period. Three types of available fuels in Iraq were tested. The tests conducted on ordinary gasoline with an octane number of 82, premium gasoline with an octane number of 92, and M20 (consist of 20% methanol and 80% regular gasoline). The 2 liters Mercedes-Benz engine was used in the experiments. The results showed that engine operation at idle speed emits high levels of CO, CO2, HC, NOx and noise. The produced emission levels depend highly on fuel type. The premium gasoline (ON=92) represents the lower emissions level except for noise at all idling speed. Adding methanol to ordinary gasoline (ON=82) showed high levels of emitted CO, CO2, HC compared with premium gasoline. Emitted NOx emissions were near zero levels for most of the idle speeds for the tested fuels.

Highlights

The climate change and the greenhouse effects became known to all as the causes of these phenomena are well known
CO concentrations were increased with increasing idling speed higher than 800 rpm while for M20 reduced with this increment
At 800 rpm, the emitted CO from ordinary gasoline and methanol was higher by 127.39% and 256.47% in relation to premium gasoline

Summary

Introduction

The climate change and the greenhouse effects became known to all as the causes of these phenomena are well known . The burning of fossil fuels produce many pollutants the environment and in its contamination [1]. Combustion of gasoline fuel in spark ignition engine is one of the most used fossil fuel. As the gasoline automotives increased profoundly in Iraq since 2003 to become more than 4.5 million cars with an increment level of 17.5% yearly [2]. About 38% of it concentrated in Baghdad the capital with about 1.75 million vehicles [3]. The Iraqi environment especially Baghdad is much polluted and highly sensitive to pollutants due to subsequent wars and dust storms, as well as, due to fossil fuels burning [4].
