Caterpillar announces the introduction of the Tier 4 Interim/Stage IIIB technology Cat C7.1 ACERT at Intermat in Paris Nord-Villepinte.

The new engine is a 7.01 liter platform with a power rating of 175-300 hp (130-225 kW) and delivers a peak torque of 944 lb.-ft. (1280Nm). The engine includes a Cat Clean Emissions Module (CEM) aftertreatment system that will meet Tier 4 Interim/Stage IIIB emissions standards.

Equipped with an A5 electronic control unit, high pressure common rail fuel system and a two-stage Smart Wastegate turbocharger, the Cat C7.1 with ACERT Technology delivers low speed response and torque as well as high power density at higher speeds. The C7.1 utilizes the full complement of ACERT building blocks including the CEM and the Cat NOx Reduction System to achieve a significant 90% reduction of PM and a 45% reduction of NOx over current Tier 3/Stage IIIA levels.
