Cat C4.4 ACERT Engine
The C4.4 engine provides 129 kW (173 hp) and meets U.S. EPA Tier 4 Final and EU Stage IV emission standards.
Eco-mode
Eco-mode utilizes an engine speed of 1650 rpm and reduces fuel burn by up to 5% over Cat E-series pavers while also lowering sound levels even more.
Automatic Engine Speed Control
When automatic engine speed control is activated, the engine speed is reduced to an idle speed of 1000 rpm when the propel lever is moved to neutral, or to 1300 rpm when screed heat is active.
Advanced Eco-mode
Eco-mode and automatic engine speed control when activated together modify the engine rpm based on load factors. When activated the engine will operate at 1650 rpm when paving. If the upper power threshold is exceeded, the engine speed will increase to 2200 rpm and remain there until the demand drops below the threshold and remains there for 30 seconds, ensuring reliable performance.
