Diesel vehicles and equipment are the work horses of our economy – collectively they play a significant role in agriculture, construction, transportation and infrastructure. The combined features of fuel-efficiency, power, reliability and durability give diesel vehicles and equipment this distinction. Diesel fuel burns more efficiently and is safer than gasoline because it does not form flammable mixtures, but there is a price to pay. Despite progress in cleaner fuels and emission standards and technology, diesel engines remain one of the largest sources of fine particulate matter, considered to be a significant threat to public health. Diesel exhaust also contributes to ozone formation, acid rain and global climate change.
