Share:
Rolling Meadows, IL, April 6, 2010- 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:
o Newly designed variable geometry turbocharger
o Newly designed DPF (diesel particulate filter)
o Heavy duty HPCR (high-pressure common rail) fuel injection system
o Larger more robust cooled EGR (exhaust gas recirculation) system
o Redesigned combustion chamber at top of piston
o Harmonized engine and machine interface by electronic control system
Komatsu has integrated this Tier 4 technology into construction and mining engines ranging in size from 3.3- to 46-liter. Through Komatsu's in-house development and production of engines, hydraulic units, control systems and major components, the company have attained exceptional machine performance under a variety of operating conditions. Komatsu customers have come to expect outstanding quality and performance, and these Tier 4 powered machines are designed to meet customer expectations while improving the environment and fuel consumption.
The engine and machine work equipment function in harmony as the electronic control system performs high-speed processing of information from sensors throughout the machine. The result is reduced fuel consumption, noise, NOx and PM.
