Introduction When someone mentions diesel, many people still have the image of a loud and obnoxious machine that is hard to start in the cold weather. This may have been true twenty to thirty years ago, but could not be further from the truth today! With all of the advancements in engine and emissions technology; diesel has become the new standard in fuel economy and power while still maintaining strict pollution standards as mandated by the EPA. As C.J. Baker explained here, “Diesel development has come a long way, but the public perception of diesel is lagging 25 years behind...but the bottom line is still the same. Modern diesels are quick, powerful, quiet, easy to start in the cold, and don't smoke.”(Baker 2). Therefore I have…show more content…
Which to someone like Gordon Fisher, whose business relies on his 5.9L Cummins Turbo Diesel to deliver heavy loads of hay tipping the scales at 40,000lbs, while still maintaining fuel economy that is twice that of his old 454 Chevy; diesel is a life saver(1). Next is cetane, cetane is as stated here by Keith Browning “...a measure of a fuel's ignition delay.”(para. 2), and is comparable in importance to a gasoline engines octane rating. This is important because a low quality diesel fuel, with a low cetane number will cause; poor performance, white smoke, and lower fuel economy (para. 2). Another plus for diesel, is that in a basic sense it is a very light oil, this helps by providing lubrication to major parts engine parts such as; fuel pumps, injection pumps, and fuel injectors.
Emissions
In the recent years the EPA has made some mandatory changes in the way diesel fuel is refined, and the amount of equipment that is required to reduce the emissions output of greenhouse gases. These changes include the change from LSD (Low Sulfur Diesel) to ULSD (Ultra-Low Sulfur Diesel) in 2006. “A high sulfur content is undesirable in fuels, such as gasoline and diesel, because it forms sulfur dioxide and sulfates during the combustion process…” (Baker, para. 2). Consequently though, removing the sulfur from the diesel removes vital lubrication properties that are critical to injection pumps operation
