Diesel engines are cleaner than ever before, and in the next few years the diesel industry will virtually eliminate key emissions associated with on- and off-road diesel equipment. This environmental progress is the result of the new clean diesel system – combining clean diesel fuel, advanced engines and effective exhaust-control technology.

Diesel is a petroleum-based fuel with a high energy content – helping diesel go further per gallon than most other alternatives. Refiners reduced the sulfur content in diesel fuel by 97 percent.

Diesel is the world’s most efficient internal combustion engine. It provides more power and more fuel efficiency than alternatives such as gasoline, compressed natural gas or liquefied natural gas.Fuel combustion is the primary difference between gasoline and diesel engines.
