Pollution Free Two Wheelers
Published on Sep 03, 2023
The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high.
The main pollutants contributed by I.C. engines are CO, NOX unburned hydro-carbons (HC) and other particulate emissions. Other sources such as Electric power stations industrial and domestic fuel consumers also add pollution like NOX, SO2 and particulate matters. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect which is going to decide the health of earth.
In this project vinegar is mixed with lime stone. Reaction between vinegar and lime stone is very fast. This mixture is contacted with the exhaust gas which is emitted from the engine exhaust valve and get well mixed and due to some chemical reactions carbon dioxide are separated.
Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms or damages the natural environment .These substances called pollutants can occur naturally or they can be produced by human activities.
Natural pollutants include dust, pollen, salt particles, smoke from forest fires, and gases from organic waste. Most pollution caused by human activities is directly or indirectly the result of burning of fuels in furnaces or engines.
The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratosphericozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
Air pollution in the world has emerged as the focus of environmental remediation efforts because of their toxicity and threat to human beings. Hence the removal of toxic air pollutant contaminants from atmosphere is one of the most important environmental and economic issues todaypollutants .
Many expensive methods of removal for air pollutants are available in developed countries but in developing countries like India these methods are hard to apply because of its cost .
WORKING OF UNIT:
As the exhaust gas passes from the exhaust port of the IC Petrol engine, it enters into the aqua silencer. The perforated tube converts the high mass bubbles into low mass bubbles. This gas in the perforated tube via the drilled holes enters into the mixture of vinegar and coal powder. Since charcoal has high adsorbing capacity, it adsorbs the harmful gases and purifies the exhaust gas.
After passing over the vinegar and charcoal mixture some of the gases dissolve in to the vinegar and finally the exhaust gases escape through the opening in to the atmosphere. The sound produced under waste medium is less hearable than to that produced in air medium hence aqua silencer reduces noise and pollution.
• More effective in the reduction of emission gases and noise,
• Vinegar and charcoal are renewable sources of energy, so it is easy to use,
• Maintenance is easy,
• It is smokeless and pollution free emission occurs,
• Performance is higher than the conventional silencer,
• In mass production it has less cost,
• Non exhaustible energy source is used,
• Eco friendly process,
• It is easy to construct and has good appearance.
ADVANTAGES OF ABSORPTION PROCESS:
• 1. It increases the coagulation power of the process,
• 2. Its use reduces the chlorine demand,
• 3. The excessive dose of activated carbon is not harmful,
• 4. The treatment process is very simple and it requires nearly no skill,
• 5. The efficiency of removing color, odor and taste is quite high,
• 6. It can be easily regenerated,
• 7. It has excellent properties of attracting gases.
Aqua silencer can be used in all the automobile field such as:
• Two-stroke engine,
• Two-stroke engine,
• Six-stroke engine,
• All automobiles using SI and CI engines,
• All types of generators.
