STRATEGIC METHOD OF REDUCING CAR EMISSIONS IN NIGERIA: ROLE OF NAVY OPERATORS.

LIKE A LECTURE PROVIDED BY ENGR. BG IBRAHIM fwc ACM (SED) AT SAFETY MANAGERS TRAINING PROGRAM AT FRSC ACADEMY, JOS ON THE 30TH AUGUST, 2009.

INTRODUCTION

1 ) In developed and expanding countries, a history of polluting of problem provides typically been high amounts of smoke and sulphur dioxide arising from the combustion of sulphur-containing non-renewable fuels such as coal for household and industrial purpose.[i] Commercial development as well as the use of non-renewable fuels have influenced the world local climate adversely. In Nigeria epileptic power supply has taken about the usage of diesel and petrol run generators nearly in all homes

2 . The transport caused environmental pollution in Nigeria, is further compounded by simply recent inflow of motorcycles and tricycles, most of which have 2-stroke search engines. Equally, the importation of used cars and insufficient vehicular emission control as well contributed to the high level of pollution in the atmosphere. Gas and diesel powered engine automobiles emit lots of pollutants, principally carbon monoxide (CO), oxides of nitrogen (NOx), volatile organic compounds (VOCs) and particulates, which have an ever-increasing impact on air quality. In addition , photochemical reactions caused by the actions of sun rays on nitrogen dioxide and volatile organic and natural compound coming from vehicles causes the formation of ozone, another long range pollutant, which impacts in rural areas often far from the initial emission site. Acid rainwater is another long-range pollutant influenced by automobile nitrogen o2 emissions. That is why vehicle release pollution danger is worsening in countries high is no sufficient legislation to its control.

3. It can be for this reason this paper requires a look at types of vehicular pollutants, factors behind pollutants in vehicles and the effects. The paper can identify methods of controlling vehicular emission, the economic and environmental advantages of controlling this kind of emissions. A lot of challenges militating against vehicle emission control in Nigeria will be highlighted before finally stating the roles expected of navy operators towards vehicular release control in Nigeria.

TYPES OF CONTAMINANTS IN MOTOR VEHICLE

3. Since the amount of cars on the road raises, so does the amount of vehicular air pollution. There are four main types of smog and all of options found in motor vehicle emissions.[ii] They are: a. Carbon Monoxide (CO) – This is a colourless, odourless poisonous gas produced by imperfect, or bad combustion of fuel including ‘cold ‘ or desperately tuned engine. As visitors is a key source of carbon monoxide, ambient concentrations will generally be greatest close to active roads. w. Hydrocarbons (HC) – Hydrocarbons are introduced through the exhaust system when fuel is unburned or incompletely burned. Considerable amounts also reach the atmosphere due to gasoline evaporation. Hydrocarbons evaporate by fuel reservoir and other fuel feed factors such as the energy line, carburettor, filter reserve canisters at the. t. c. Hydrocarbons likewise vaporize once fuel place storage depots and automobile tanks and so are. c. Nitrogen Oxide (NOX) – Fuel burning in high temperatures produces nitrogen oxide. During the combustion process, this temperature can reach 2500 degree Grad. At these types of temperatures nitrogen and oxygen from the air flow in the combustion chamber react to form nitrogen oxide deb. Particulate Matter – Automobiles will create particles possibly from immediate emissions in the burning of fuels (especially diesel run vehicles) or perhaps from wear of tyres or automobile generated surroundings turbulence in roadways. Contaminants may be generated from the actions of blowing wind on the heavy materials the vehicle can be carrying.

5. At an appointment on clean air, clean energy sources and automobiles in May 2006, the then Minister of Transport, Doctor, Abiye Sekibo revealed that Nigeria's transport sector as a whole...
