Power to move more dirt with less fuel
Cat ® C18 Engine
The C18 engine with ACERT™ Technology powers the 390D L. The C18 has a proven record of long
life. Materials like high-strength steels and cast iron contribute to its durability, while uniquely designed
water-cooled turbochargers and mechanically actuated fuel injection contribute to its reliability.
Improved Fuel Effi ciency
The 390D L optimizes fuel consumption through fl exible power settings incorporated into the
ADEM™ controller, which electronically manages engine response to load demand. The operator
can select High Production, Standard or Economy mode to meet application requirements.
Hydraulic Cooling Fans
The 390D L uses hydraulically driven cooling fans that operate based on coolant and hydraulic oil
temperatures. To reduce load when cranking the engine, the cooling fan speed is fi xed for a set amount
of time after the engine is started and then is increased gradually to a specifi c speed.
Reversible Fan
A reversible fan option is offered to help clean the cooling package for increased uptime and reduced
service cost.
