Tier 4 Final Crawler Dozer:
Turbocharger Helps To Keep Filter Clean
The D61-24 Crawler Dozer is powered by a 6.80-liter, 168-hp diesel engine that meets Tier 4 Final emissions standards via a diesel-particulate filter. The engine employs a Komatsu variable-geometry turbocharger, which maintains a high level of passive regeneration, reducing time lost on cleaning out the exhaust filter. Operators can choose between a quick-shift, three-speed mode or a variable 20-speed, customizable transmission mode as needed. Komatsu America Corp.; www.komatsuamerica.com
