clean air into the combustion chamber to reduce emissions and enables “Gear Fast, Run Super Slow” driving techniques to optimize fuel economy

“Leak-free” technology — Significantly reduces leaks to cut downtime and improve reliability Catcompression brake — 600 retarding horsepower now available on the C15

for Bottom-Line Value Toda
How do Cat® engines with ACERT ™ Technology meet tougher 2007 emissions standards while maintaining top performance and excellent fuel economy? With refinements to the same innovative approach proven successful over millions of miles: using more cool, clean air for more efficient combustion. Still aSystems Solution
The systems solution of ACERT Technology, a proven success, hasn’t changed for 2007. Its four basic systems of Air Management, Precision Combustion, Advanced Electronics and Effective Aftertreatment are still the building blocks for reduced emissions, powerful performance and outstanding fuel economy.
Cat Designed InjectionTechnology Clean Gas Induction

New Clean Gas InductionClean Gas Induction (CGI) is a proprietary ACERT Technology process that draws off a small amount of non-combustible gas after it has passed through the engine’s aftertreatment system. The gas is then cooled, blended with more incoming cool, clean air and returned to the combustion chamber. Since it has passed through the diesel particulate filter, most contaminants have been removed before the gasre-enters the intake system.
