Engine
Delivering the most work per liter/gallon of fuel consumed
The Cat ® C4.2 engine with ACERT ® Technology optimizes performance and meets U.S. EPA Tier 3 and EU Stage IIIA regulations.
In conjunction with integrated electronics, ACERT Technology reduces emissions during the combustion process by using advanced
technology in the air and fuel systems. The Cat C4.2 engine delivers exceptional power, allowing more hydraulic pressure to drive
productivity and reduce your cost per ton of material moved.
Automatic Engine Control and Fuel Delivery
A two stage engine speed control and one-touch low idle button maximize fuel effi ciency and reduce sound levels. Fuel delivery is
managed by the ADEM™ A4 Engine Controller for the best performance per liter (gallon) of fuel used. Flexible fuel mapping allows
the engine to respond quickly to varying application needs.
Crankshaft and Pistons
A forged, one-piece, induction hardened crankshaft enhances balance, decreases vibration and improves abrasion resistance.
Heat resistant, aluminum alloy pistons have a short compression height for greater effi ciency and longer life.
Economy Mode
Accessible through the in-cab monitor, economy mode allows you to balance the demands of performance and fuel economy while
maintaining the breakout forces and lift capacity enjoyed at standard power.
