Komatsu America Corp. is pleased to announce the introduction of its new diesel engine that features the next generation of engine technology designed to meet US EPA non-road Tier 4 interim emission regulations. Based on Komatsu proprietary technologies developed over many years, the new diesel engine reduces exhaust gas particulate matter (PM) by more than 90% and oxides of nitrogen (NOx) by more than 45%--when compared to current Tier 3 levels--while still consuming less fuel.

Komatsu’s Tier 4 engine technology includes:

» Newly designed Variable Geometry Turbocharger
» Newly designed Diesel Particulate Filter (DPF)
» Heavy duty High-Pressure Common Rail (HPCR) Fuel Injection System
» Larger more robust cooled Exhaust Gas Recirculation System (EGR)
» Redesigned Combustion Chamber at top of piston
» Harmonized engine and machine interface by Electronic Control System

Komatsu has taken some interesting steps to help ease the transition to Tier 4 by offering Komatsu Care a support program that will be standard on all construction size Tier 4 Interim machines, along with two complimentary Komatsu Diesel Particulate Filter exchange units for the first five years, or 9,000 hours, whichever comes first. The KDPF exchange will lower the cost of machine ownership and reduce downtime compared to cleaning the filters.
