Cat® engines with ACERT™ Technology reach important benchmark


Caterpillar® off-highway earthmoving machines with ACERT™ Technology have accumulated an estimated 10 million hours of operation.

Caterpillar has announced a significant benchmark for its state-of-the-art emissions reducing engines featuring ACERT Technology. Total usage is estimated to exceed 10 million hours. There are also over 320,000 on-highway truck engines equipped with ACERT Technology on the road today.  ACERT has truly become a proven technology.

“We’ve reached a significant milestone in delivering engines that meet all current EU Stage IIIA regulations.  With Cat on-highway truck engines with ACERT Technology now accumulating over 175 million km everyday and a rapidly growing population of new Cat machines in the field, ACERT Technology has proven itself by delivering superior customer value. ,” said Paolo Fellin, Vice President of Marketing for Europe, Africa and the Middle East.

ACERT Technology uses a systems approach to meet EU Stage IIIA emission requirements.  Through precise integration of air, fuel and electronic control systems, Cat has been able to meet the rigorous EU Stage IIIA emission regulations without sacrificing the performance, reliability and durability that customers expect from Caterpillar.

ACERT Technology relies on improvements made to proven systems to meet emission requirements.  Airflow through the engine is improved through the use of a wastegate turbocharger and cross-flow cylinder heads.  Electronically controlled fuel injectors provide multiple fuel bursts allowing for more complete fuel burn during combustion. The correct combination of these systems ultimately optimizes the combustion process, thereby reducing NOx and particulate matter in the exhaust.

The Cat engines with ACERT Technology that meet Stage IIIA and power the 52 different models of Cat machines currently available do not recirculate exhaust gas through the engine.  This contributes to these engines being tolerant of varying sulfur levels in diesel fuel, lessens heat rejection, and eliminates the need for the addition of the many new components required for cooled exhaust gas recirculation (EGR). As a result, Caterpillar has been able to maintain a high percentage of proven components, keeping new parts content to an average of only 10% across the different models compared to 50% or more new parts content required for other solutions.

ACERT also has a lower rate of soot accumulation both on internal engine components and in the engine oil. Higher soot accumulation in EGR engines may accelerate wear of engine components and speed oil degradation. Because ACERT Technology uses clean air for combustion, Cat has maintained – and in some applications increased – engine oil change intervals at a consistent 500 hours across the product line.

In the United States, J.D. Power and Associates awarded the Caterpillar C-15 for ranking “Highest in Customer Satisfaction with Vocational Heavy-Duty Diesel Truck Engines” in a study of 2003 model year heavy-duty truck engines/transmissions.  The J.D. Power and Associates study of over 2,400 users of two-year-old large on-highway trucks measured customer satisfaction with three vital engine factors: engine quality and warranty, engine performance, and engine noise and vibration.  A Caterpillar engine has ranked highest in the vocational segment all five times the award has been given, demonstrating Caterpillar engine superiority.

ACERT Technology has been hailed as a "revolution through evolution," designed to not only meet today's clean air regulations, but also establish the building blocks for attaining tomorrow's more stringent standards.  Most importantly, ACERT Technology provides Cat customers with the reliability, durability, and performance Cat engines have been known for over the past eight decades.
Amongst the latest models of CAT  machines , with the ACERT Technology  already supplied on the local territory by Scomat Ltee  are the Wheel loaders , Hydraulic excavators ,marine engines and various generator sets engines.
