What is ACERT Technology?

ACERT Technology is an innovative performance enhancement and emissions reduction solution for diesel engines.  Caterpillar created and developed ACERT as part of a long-term effort to create cleaner-running engines that maintain performance, efficiency and service life.  

During the development of ACERT Technology, Caterpillar has been awarded or has applied for over 250 new patents.  In addition, Caterpillar has invested $500+ million in R&D for ACERT Technonolgy to date during the development porcess, Caterpillar explored a number of other possible emissions reduction solutions but chose not to continue to pursue them all when they proved to offer insufficient value to customers.

The key breakthrough of ACERT is advanced combustion technology that provides a higher degree of control over a larger number of combustion variables than ever before possible.  This control, combined with advances in air management, electronic control and, in some applications, aftertreatment, improves the overall performance of diesel engines while reducing harmful emissions.

Along with enhancing overall engine performance, ACERT enables Caterpillar to produce on-highway truck engines, off-road machines and engines for marine and industrial application that will meet increasingly stringent worldwide emissions standards.

These standards and guidelines cover a comprehensive set of tiered emissions regulations for diesle engines now being phased in by regulatory bodies in the US and European Union (EU), plus standards for marine engines set by the International Maritime Organisation (IMO).

Cat engines with elements of ACERT Technology for on-highway applications were first introduced in October 2002.  ACERT Technology is now being introduced in  off-road applications.
