Clean Diesel Technology
Learn how clean diesel technology combines clean diesel fuel, advanced engines and effective exhaust- control technology.
What is Clean Diesel?
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. Next »
The Fuel
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.This new, ultra-clean fuel is important because sulfur tends to hamper exhaust-control devices in diesel engines, like lead once impeded the catalytic converters on gasoline cars.

The Engine
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 liquified natural gas. Fuel combustion is the primary difference between gasoline and diesel engines. Gasoline engines ignite fuel with spark plugs, whereas diesels ignite fuel with compression. Next »
The Exhaust
With the introduction of lower sulfur diesel fuel, a number of exhaust treatment systems can further reduce emissions from diesel engines. Particulate Traps – collect particulate matter as the exhaust gases pass through and can reduce particulate emissions by 80-90 percent using a catalytic reaction or an auxiliary heating element. Catalytic Converters – use a chemical reaction to convert emissions into harmless substances. Next »
