HYBRID VEHICLES THEIR IMPACT ON AIR POLLUTION IN ASPECT OF CHEMISTRY

INTRODUCTION

The world 's engine and turbine systems have so far been powered by fossil fuels . In recent times however , there has been the rise of green gas or alternative energy use . Even cars that were traditionally powered by diesel and petroleum derived fuels have en modified to use green gas and fuel cell systems . Hybrid vehicles use energy systems that can be recharged and the movement system of the vehicle depends on refuel ling procedures like the use of green

gas

The hybrid nature refers to the ability of the vehicle to use a blend of vehicles that are not necessarily limited to the conventional fossil fuels

In 2001 the American administration embarked on a green vehicle project popularly known a freedom car initiative . Whereas the final goal of the initiative was to reduce pollution through the use of fossil fuels-free-vehicles , hydrogen is derived from the same fossil vehicles and is used t drive vehicles . In spite of this hybrid vehicles have had an impact on the nature and composition of environmental gas

The air pollutants form fuel burning appliances occurs as mixture of gases , solids (suspended particles ) and liquids suspended droplets . A mixture of particulates and droplets is commonly called aerosol for this particular the tem smoke will refer to the entire mixture f pollutants from combustion aerosol plus gases . The pollutants in biomass smoke are essentially entirely created during the combustion process used and it does not exists in fuel before hand ' as is addressed in Biofuels air pollution and health by Smith K .R pages 28

METHODOLOGY

The study focused on the levels of concentration of green gas products Other emission form hybrid vehicles and chemical effects on the environment . This calls for undertaking a number of activities including recognizing a particular chemical pollutants emitted from hybrid vehicles as a potential environmental concern

OBJECTIVES OF THE STUDY

The research undertook a major step in recognizing the emission form hybrid vehicles in both qualitative and quantities manner . It also monitored the chemical emission in hybrid vehicles particulate their impact on air pollution . In particular the study focused on levels and chemical effects of carbon monoxide , carbon dioxide , nitrogen oxides , dark smoke and particulates

PROCEEDINGS

Results indicate that hybrid vehicles and other auto mobiles are the major source of primary air pollutants . Transpiration is responsible for major air pollutants (over 50 ) in the USA . carbon monoxide and hydrocarbons are major pollutions and it is for this reason that transportation is generally considered responsible for about 50 or current air pollution ' as documented in studies in environment science 44 , highway pollution by Ronald S . Hamilton page 10

The result from individual pollutants obtained from hybrid vehicle emissions are independently detailed as shown below

Carbon monoxide

It was identified as the largest part of hybrid vehicle emission . In complete of fossil fuels in hybrid vehicles is its chief source

Without pollution controls these engines emits an average of...
