Diesel particulate filter

It is a known fact that we as a society are having a major affect on the earth’s atmosphere. Since the Industrial Revolution technologies have advanced and a lot of our means of energy give off harmful pollution. Mass production has allowed the number of cars in production to grow exponentially, and the increasing population is keeping them in demand. Pollution is at an all time high now and continues to get worse with the growing populations. More and more people are driving vehicles and able to

ABSTRACT Diesel engine exhaust gas emissions and particulate matters have been a serious environmental problem for a long time. Many research have been made in order to reduce these emissions since the usage of diesel engines came into large. Major emissions from the diesel exhaust are NOx, SOx, CO and Particulate Matters. Amongst these SOx, CO and Particulate matters can be reduced by using after treatment methods like Catalytic Reduction, etc. Unlike these NOx reduction is a challenging issue

Ozone is a form of oxygen (O3) and a major air pollutant in the troposphere. It is very harsh and irritant to the lungs, and can be a serious problem for people with lung disorders. Ozone in the stratosphere, on the other hand, is good and acts as a filter to the sun’s harmful rays which can reach the earth’s surface, causing skin cancer to the

focus on regulating the amount of material that can be released by the automobiles and the amount of smog forming material that can be released. Standards generally regulate the amount of carbon monoxide, oxides of nitrogen, the sulfur, HC and particulate matter (PM) that

In a number of instances air pollution can not be seen with the naked eye, however it can be seen when clouds of particulate matters appear above a city. As disturbing as seeing polluted air is, it is the unseen pollutants that is a greater danger. Environmental psychology tells us that personal manners and behavior have an effect on the environment. By doing research on how we harm our environment, processes may be put in place to off set and limit such behaviors. Bio-fuel, wind energy, solar

When the filters are so carelessly thrown out of the car, or tossed on the corner of a sidewalk, the chemicals from these non-biodegradable butts absorb into the ground. Giovanni Invernizzi, of the Tobacco Control Unit of Italy's National Cancer Institute, put forth a study to see just how much air pollution is produced from tobacco. The results were unbelievable! According to the study, just three cigarettes can cause more air pollution than the exhaust from a diesel car! The study compared

1. Definition of air pollution Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as

As the person in charge of creating a sustainable plan for families in Africa, my main goal is to develop techniques, and find alternative solutions to improve their quality of life. My mission is to establish a balanced footprint system; that simultaneously ensures that every renewable project has the highest technical, and environmental quality. The intended purpose is to implement this plan for the less-fortunate people with the long-term goal of the improvement of the environment. Power energy

preventions and treatments for asthma in order to prevent mortality. There are a number of contributing factors in the increase of childhood asthma; for instance, sensitization of allergens, cultural beliefs, and environmental factors, gas and diesel emissions due to the high volume of traffic from the interstates in the surrounding areas. Furthermore, behavioral choices made by parents and other adults are added factors in the increase of asthma rates in children; for instance, mothers that smoke

Chapter 1 INTRODUCTION Diesel engine is a very popular prime mover used for surface transportation, agricultural machinery needs and in industries. Diesel engines of more than 6.5 million units are being used only in the Indian agricultural sectors for different activities and the import of petroleum products is a major draw off on our foreign exchange sectors and with increasing demand in future years the condition is likely to become worse. Hence, it is an urgent need for a country like India
