Komatsu D61-23 Achieves Fuel Gain, Boasts New Blade

摘要

Two gearshift modes also give dozer operators many speed settings to tailor their speed to the job. Komatsu's D61-23 crawler dozer has a Komatsu Tier 4-Interim SAA-6D107E-2 engine that provides the same horsepower as its predecessor, while lowering fuel consumption by up to 10 percent, the company says. The engine provides 168 net horsepower at 2,200 rpm and uses Komatsu's Tier 4-Interim engine platform with an advanced electronic control system to manage airflow rate, fuel injection, combustion parameters, and aftertreatment functions.
