The Pros And Cons Of Engines

Engines have had emissions control since the 1970s. Emissions controls were first introduced to engines because a growing number of people had difficulty breathing, and many illnesses attributed to the harmful emissions produced by the internal combustion engine. The environment also held noticeable damage in certain areas which resulted in the EPA (Environmental Protection Agency) being created. The regulations are updated every few years by the EPA. Most big industries frown upon the EPA because they tend to complicate business practices. In actuality, the EPA is effective and without them the earth would lead a very dirty, hard to live in existance (EPA). They control things like air, water, waste pollution, through sets of laws they …show more content…
The diesel engines downfall is particulates, which is what a person can actually see in the form of black smoke. Particulates actually are not as harmful as the pollutants a person cannot see from gasoline engines. Particulates are heavier than air so they float back down and hit the ground which then causes a water and soil pollution problem. This also produces ground level ozone which causes acid rain. Vehicles produce harmful emissions like, hydrocarbons which cause heart disease, and cancer, and is an ingredient of creating smog. Engines also create carbon monoxide which is similar to hydrocarbons, they cause the same illnesses and hurt the ozone in the atmosphere that humans use to breathe. Engines produce NOx, or nitrogen dioxide, which is arguably the most harmful, NOx is produced when nitrogen in the air mixes with the high heat and extreme pressure in the engine. The Selective catalyst reduction systems can eliminate NOx, by mixing urea, which is a mixture of ammonia that converts NOx back into regular nitrogen …show more content…
Gasoline engines are mostly only in cars and small equipment, but diesel are in boats and a variety of other things that would only be possible with such engines, which is why the EPA is so focused on the diesel engine. Diesel engines also have the potential to be extremely dirty if not regulated by the EPA and various manufacturers (Kavanagh). Various operators also think that the laws do not really matter in relation to the operation of their engines because they stand in the way of their profit to be made, in which case the laws are not enforced hard enough. Companies also sell emission equipment delete kits, which is against the law, but can be sold for “off-road use only” (DMV). While it is illegal to equip an on-road vehicle with a delete device, many independant mechanic shops will install them and will pass the vehicle in later inspection tests (EPA). A crackdown from the EPA is in order to ensure these laws are enforced, after all there is a reason these devices were installed in the first place.
Ways to save the environment through emissions control, is under research everyday because so many people realize how big of a problem air pollution is. The EPA will continue to make standards stricter until vehicles can run, and have no bad or even a good impact on the environment which is a fantastic thing. A better environment is a very important
