Komatsu America Corp's New WA380-8 Wheel Loader Features Tier 4 Final Engine

July 15, 2015

Komatsu America Corp., has introduced the new WA380-8 wheel loader. With a 6.69 litre, 191-hp Komatsu SAA6D107E-3, variable geometry turbo charged and after-cooled Tier 4 Final certified engine, the WA380-8 uses up to six percent less fuel than its Tier 4 Interim predecessor.

Komatsu’s SmartLoader Logic software combines with a lockup torque converter, which activates in second, third and fourth gears. Together, the system provides optimal engine torque for improved acceleration, hill climbing, a higher top speed and fuel savings.

“With one of the highest breakout forces in its class and excellent balance, this machine is made for tough digging tasks,” said Craig McGinnis, Komatsu America product manager. “The WA380-8 is ideal for carrying pipe, sand and other aggregates, site cleanup and support, digging into piles and backfilling,” McGinnis said.

Komatsu designed the machine’s Komatsu Diesel Particulate Filter (KDPF) and other aftertreatment components to work in harmony with the engine for efficiency and long life. A Selective Catalyst Reduction (SCR) assembly is incorporated to further reduce NOx emissions using diesel exhaust fluid (DEF). The engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions and provide advanced diagnostic capability.
