Overview: Diesel Engines move the economy and without them commerce would come to a grinding halt. However they have harmful effects on the environment and are one of the most heavily regulated machinery components involved in commercial vehicle manufacturing. Another source of concern is the frequent uncertainty of fuel costs which fluctuate often. Caterpillar one of the worlds largest Diesel Engine Manufacturers and heavy equipment expert has found a solution with new ACERT technology.

ACERT Fuel systems allow for for more than one fuel injection per cycle spritzing diesel fuel in the chambers twice per cycle improves emissions. ACERT Cylinder Heads are complex and CAT had to experiment with over 125 different combustion cycles out of a possible 10 million to get the precise timing correct. Spritzing two injections per stroke means that each stroke is more productive, improving efficiency.

ACERT engines also have improved Air Systems which use additional turbochargers to push more cool air into the combustion chambers. (Compressed Air + Atomized Diesel Fuel = Explosion or "Powerstroke") One of the most notable distinctions of ACERT engines is they have a "Wastegate" Turbocharger which provides additional power for lower end performance. This provides a distinct audible sound no other engines produce during low end power. These engines typically perform in the 300 to 700 Horsepower range and are used for many different applications such as Marine Engines and Work Site generators.
