The Pros And Cons Of Diesel Engines

Diesel engines outperform and produce less emission rates on Earth than gasoline engines. On the other hand, gasoline engines cost less to run daily. With the EPA making diesel emission standard more stricter, the emission rate for diesels have decreased. Also with different equipment being installed to diesels, the power has increased too. How much have the EPA standards lower the emission rates? Ever since the EPA has enforced standards for diesel engines, the emission rates have progressively dropped key pollutants by 75 percent (“Air Pollution” 1). Also, to meet EPA standards in 2007, the EPA were requiring refiners to produce 80 percent of diesel fuel to be low-sulfur grade (“Air Pollution” 2). As of June 1, 2006, the EPA requires refiners for diesel fuel to begin producing fuel with no more sulfur content than 15 parts per million which is a 97 percent reduction (“All Pollution 14”). Since 1984, EPA has been enforcing stricter diesel emission standards, which decreased the acceptable level of nitrogen oxide emission for diesel engines from 10.7 gram per unit of work in 1988 to 2.5 grams in 2004 (“Air Pollution 10”). To help reduce diesel emissions, “The Clean Air Act” bans manufacturers from selling or installing components that can bypass or render inoperative the diesel emissions control system on the truck (“All Pollution 11”). If the companies are found selling or installing components that can bypass or render inoperative the diesel emissions control system
