The diesel engine is the workhorse of the transportation and power-generation world. The vast majority of big rig trucks, public transit and rail engines run on diesel. Virtually all commercial marine, construction and conventional power-generation engines are diesel powered. Diesel engines offer more horsepower, high durability and lower maintenance costs. Until recent years, diesel fuel has been priced lower than gasoline.
Diesel engines - particularly older ones often spew oily clouds containing particulate - soot. Diesel trucks may represent as much as 30 percent of the nitrous oxygen and 65 percent of the soot that is spewed into the air.
Tug boats have the been identified as the biggest individual category of polluters, XTENDER programs have cut pollution by up to 50 percent while increasing fuel efficiency 6-8-10-12%. Legislated formulation changes in some diesel fuels have reduced sulfur content to reduce emissions. Unfortunately, that change also reduced the lubricity of the fuel, reduced fuel efficiency and sharply increased engine maintenance costs.
Every XTENDER program addresses this range of issues effectively and economically. Superior lubricity replaces the lubricity lost by the removal of sulphur, cleaner burn results in improved efficiency, its cleaner burn reduces emissions and its cleaner burn reduces maintenance costs.
