 V-ACT engine

Tier-3 compliant Volvo Advanced Combustion Technology (V-ACT) engines provide power and torque over a broader engine speed range. Other benefits include improved engine response at low engine speeds and optimal fuel efficiency. The system does not use external after-treatment or EGR. Instead of using variable geometry turbochargers, the engines have simple fixed geometry turbos.
