Komatsu Diesel Particulate Filter (KDPF ) Komatsu has developed a high efficiency diesel particulate filter that captures more than 90% of particulate matter. Both passive and active regeneration are automatically initiated by the engine controller depending on the soot level of the KDPF. A special oxidation catalyst with a fuel injection system is used to oxidize and remove particulate matter while the machine is running so the regeneration process will not interfere with daily operation. The operator can also initiate regeneration manually or disable regeneration depending on the work...

Productivity & Ecology FEaturEs outstanding Productivity SIGMADOZER – The Next Generation Blade Based on a completely new digging theory, SIGMADOZER dramatically improves dozing performance and increases productivity. A new frontal design concept adopted for digging and rolling material up at the center of the blade increases soil holding capacity while simultaneously reducing side spillage. It also reduces digging resistance, producing a smoother flow of earth, enabling the dozing of larger quantities of soil with less power. Production SIGMADOZER Increased By Fuel Consumption Decreased By...

other Features Auto Pitch Mode* To reduce operator effort and increase operating efficiency the new auto blade pitch mode sets blade pitch position between digging and dump positions while dozing. By pressing the auto pitch switch it will toggle the pitch position from digging to dump position with no additional lever movements. The blade pitch control can be set through the monitor to automatically return to the digging position when reverse is selected.
