contributes to air quality problems. All motor vehicles exhaust fumes coming out of the tailpipe when the engine is running mostly through the air pollution issue. Tailpipe emissions of vehicle engines burning fuel‚ the products are emitted from vehicle exhaust system. Vehicular pollution is the worst thing about that as vehicular emissions at ground level to where we are emitted in the breath can not be avoided. Causes of vehicular pollution • High vehicle density in Indian urban centers. •

pollution emitted during vehicle operation‚ refueling‚ manufacturing‚ and disposal. Additional emissions are associated with the refining and distribution of vehicle fuel. Air pollution from cars and trucks is split into primary and secondary pollution. Primary pollution is emitted directly into the atmosphere; secondary pollution results from chemical reactions between pollutants in the atmosphere. Vehicle Emissions and Air Quality When a car’s engine is running‚ several different types of gasses and

In January 2010‚ the U.S. Environmental Protection Agency (EPA) brought in new emissions standards requiring medium- and heavy-duty vehicles to significantly reduce engine emissions‚ particularly NOx and particulate matter (PM). Vehicle manufacturers use SCR to meet these standards. DEF is sprayed into the exhaust‚ breaking

THE CARBON CYCLE According to the United States Environmental Protection Agency (“EPA”)‚ the increase in anthropogenic CO2 emissions has led to the increase in global temperatures in the past century . Because of the preponderance of evidence linking greenhouse gases and climate change‚ governments worldwide are developing policy to reduce CO2 emissions. CO2 can enter the atmosphere by burning fossil fuels‚ in manufacturing processes‚ and other energy-reliant activities. However‚ not all emitted

whether or not the climate actually was changing‚ but now‚ science has evidence and proven that the climate certainly has been changing. The changes are primarily a result of the emissions of greenhouse gases‚ in particular carbon dioxide‚ and experts claim that a number of human activities are the reason for the emissions. The exact consequences of global warming are still unknown‚ but the question is no longer what will happen‚ the question is “How do we solve this problem?” That having said‚ global

Every year‚ almost 7 billion tons of carbon dioxide is released into the atmosphere by human activity (“How do we contribute individually to global warming.” Global Warming: 2006. Web.12 Oct. 2011). That is the equivalent of 107‚700‚000 jet airplanes being in the air at once! This harrowing figure is the main cause of global warming‚ and has been increasing for the last 50 years. Global warming is caused by the increase of greenhouse gases‚ carbon dioxide and methane primarily‚ in the earth ’s upper

HCNG vehicle offers the potentials for immediate emission benefits‚ reduction in NOx/ SOx emission‚ which eventually affects positively on our environment. At the same time they can pave the way for a transition of fuel cell vehicles by building early demand for hydrogen infrastructure and vehicle fueled with hydrogen based
