Mitsubishi Forklift Trucks’ FD40N1-FD55N1 Series 8,000-12,000 lb. capacity diesel pneumatic tire forklift trucks feature a new diesel engine that provides a 21.6% increase in fuel efficiency. The engine, which is designed to meet the U. S. Environmental Protection Agency’s (EPA) Tier 4 Final emissions standards, also offers increased performance and reduced emissions levels. The Perkins 854F engine operates without requiring any ash service. The engine also features low-noise levels, which helps to reduce operator fatigue throughout the shift. The diesel particulate filter automatically regenerates during normal operation, eliminating work cycle interruption, even at low engine speeds. The diesel-powered engine also features a 21.6% improvement in fuel consumption, in addition to the 90% reduction in particulate matter and the nearly 50% reduction of NOx.
