Heavy-duty cooled Exhaust Gas Recirculation (EGR) system Komatsu Variable Geometry Turbocharger (KVGT) system The system recirculates a portion of exhaust gas into the air intake and lowers combustion temperatures, thereby reducing NOx emissions. EGR gas flow has been decreased for Tier 4 Final with the addition of SCR technology. The system achieves a dynamic reduction of NOx, while helping reduce fuel consumption below Tier 4 Interim levels. The KVGT system features proven Komatsu designed hydraulic technology for variable control of air-flow and supplies optimal air according to load...

PERFORMANCE FEATURES Low Fuel Consumption Large Capacity Body A variable displacement piston pump consumes engine power only as needed to eliminate unnecessary Power Take-Off (PTO) inefficiencies. Design improvements to the drive axles as well as the transmission have been implemented to reduce driveline parasitic losses. The electronic engine control has been updated with the inception of the SCR technology to conform to EPA Tier 4 Final emissions standards. All of these factors combine to allow for the new HM300 to operate at the same performance level as its predecessor while improving...

Komatsu Traction Control System (KTCS) Articulation angle sensor Acceleration sensor Tire revolution sensor Intrer-axle lock Independent brake Tire revolution sensor Independent brake Good Free differential Turning performance The KTCS was developed by Komatsu to allow for maximum machine performance in soft and slippery ground conditions. Komatsu leveraged its prior experience with the traction control systems in bulldozers and rigid dump trucks to develop this system for use in articulated dump trucks. The KTCS monitors the wheel speeds on the front and middle axles. If the system detects...
