Air pollutants is a matter in the air that can have animpact on human health and ecosystem. Air pollution contains substance likecarbon dioxide, sulphur oxides, nitrogen oxides, carbon monoxide,chlorofluorocarbons and many more.
Therefore, it has impact on human healthespecially on the cardio-respiratory system. People with early respiratoryconditions, such as asthma and allergies, are especially vulnerable to airpollutants. The effects on human health can include reduced lung function,heart disease, stroke, respiratory illnesses, and lung cancer. In economicterms, health impacts are hard to quantify, but studies suggest they may besubstantial. According to the news from The Star over the period between 2005and 2010, “outdoor air pollution caused 6,251 deaths in Malaysia in 2012,according to a recent report by the World Health Organization. The deaths weredue to heart disease (3,630), stroke (1773), lung cancer (670), pulmonarydisease (148) and lower respiratory disease (29).” According to department of environment, 70 percent sourceof air pollution is from motor vehicles are particularly harmful for humanhealth as the general population has a higher level of exposure to motorvehicle exhaust emissions than the emission from power plant that consists 24.
3percent. While industrial and others consists small amount of percentage whichis 2.8 and 2.9. Motor vehicles are a major contributor to these pollutants inurban air sheds, and their emissions are increasing as vehicle usage continuesto rise as a result of economic and population growth.
In order reduce the problems of carbon monoxide from internalcombustion engines we saw a need for alternative fuelled vehicles that is electriccar which is electrical powered vehicle. This electrical powered vehicle ismove by an electric dc motor, supported by rechargeable battery, on behalf ofgasoline engine. The dc controller gets its power from a rechargeable batteryand electric dc motor gets its power from a dc controller. This car looksnormal like other vehicle from outside.
Only the inner part of engine functionselectrically. Often, the only clue that can detect electric car is nearlysilent.
