D375A-8 Dozers

Powered by a new technology Komatsu engine, the D375A-8 sets the industry standard in terms of operator comfort and control, while delivering higher production and lower operating costs for mining and heavy construction applications. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX PLUS remote monitoring and location system, backed by our Australia-wide service and support network.

Heavy-duty aftertreatment system

KDPF captures more than 90% of Particulate Matter (PM). Special oxidation catalyst and extra fuel injection in the exhaust stream can decompose accumulated soot in the KDPF filter by either active or passive regeneration. This system does not require any additional operator's action or interrupt normal operation.

Heavy-duty cooled Exhaust Gas Recirculation (EGR) system

The system recirculates a portion of exhaust gas into the air intake and lowers combustion temperatures, thereby reducing NOx emissions. While EGR gas flow isincreased, by incorporating a high-efficiency and compactly designed cooling system, the system achieves a dynamic reduction of NOx, while helping to reduce fuel consumption.
