PRODUCTIVITY FEATURES Komatsu Technology Komatsu’s new “ecot3” engines are designed to deliver optimum performance under the toughest of conditions Automatic Idling Setting System (AISS) This system facilitates quick engine warm-up and cab cooling/warming. When setting the system ON, engine idle speed is kept at 945 rpm when coolant temperature is 50°C 122°F or lower. Speed automatically returns to 725 rpm when coolant temperature reaches 50°C 122°F. while meeting the latest environmental regulations. This engine is Tier 3 EPA, EU Stage 3A and Japan emissions certified. “ecot3” – ecology...
