Emissions from diesel and gas engines contribute to serious public health problems not just in the U.S. but of the world. These problems include premature mortality, aggravation of respiratory and cardiovascular disease, aggravation of existing asthma, acute respiratory symptoms, chronic bronchitis, and decreased lung function. Numerous studies also link diesel exhaust to increased incidence of lung cancer.
gas emissions's effect
For example, on-road diesel-fueled vehicles contribute approximately 27 percent of the NOx emission inventory and 62.5 percent of the PM emissions. An older, dirtier diesel vehicle can emit almost 8 tons of pollution per year. This amounts to 160 to 240 tons of pollution over the life of the engine. A heavy-duty truck can create the same amount of air pollution as 150 passenger cars.
For these reason, each State has its own set of emissions standards. The European Union has its own set of emissions standards that all new vehicles must meet. Currently, standards are set for all road vehicles, trains, barges and ‘nonroad mobile machinery’ (such as tractors). No standards apply to seagoing ships or airplanes. The emissions standards change based on the test cycle used: ECE R49 (old) and ESC (European Steady Cycle, since 2000).
In the United States, emissions standards are managed by the Environmental Protection Agency (EPA). The state of California has special dispensation to promulgate more stringent vehicle emissions standards, and other states may choose to follow either the national or California standards.
In the Japan, The amended rule is called the “Law Concerning Special Measures to Reduce the Total Amount of Nitrogen Oxides and Particulate Matter Emitted from Motor Vehicles in Specified Areas”, or in short the Automotive NOx and PM Law
The Solutions
Vehicles are very important tools for transportation, but they have harmful effects on the environment and health. Fortunately other power sources and fuels are being developed to serve as an alternative.
And now, more and more people are becoming aware of how much mankind has affected the planet. The need for solutions is recognized more than ever to address environmental issues. Due to this hybrid cars are becoming increasingly popular to consumers.
Hybrid vehicles work by using an internal combustion engine which uses fuel and a rechargeable energy storage system. By using the combination of these two power source the vehicle will be able decrease fuel consumption, reduce pollution and leads to lesser emissions.
