New Crawler excavator - rent Used cat excavator 320B

With four suction/exhaust valves,

central combustion chamber and large

turbocharger with intercooler, the engine

delivers big power. What’s more, the HIOS

hydraulic system, designed for optimal

hydraulic energy control responding to

engine speed, saves fuel consumption.

The auto acceleration (A/A) mode can automatically control

engine speed according to control lever stroke to reduce fuel

consumption greatly in light-duty operations, such as grading and

finishing.

Furthermore, in the auto acceleration mode, the auto idle (A/I)

decreases engine speed to save fuel consumption, when waiting

a dump truck to arrive, with the control lever in

neutral.
