Komatsu’s Environmental and Social Activities Enhancing Quality of Life


Mitigating Climate Change (Mitigating Climate Change through Products and Services)  Tier4 Final Compliant Models Released

In 2015, Komatsu released one vehicle model after another that greatly reduce nitrogen oxide (NOx) and particulate matter (PM) emissions that meet Japanese (Emissions from Non-Road Special Motor Vehicles 2014 Standards), North American (EPA Tier4 Final), and European (EU Stage IV) emissions controls for Hydraulic Excavators, Bulldozers and Wheel Loaders. These models are equipped with newly developed next-generation engines that result in construction machinery that are clean and fuel efficient, with excellent durability and reliability. (For details, please refer to Environmental Report 2013 “Developing the Latest Engine Technology”).

Below are some examples.

Large-Sized Hydraulic Excavator “PC300(LC)-11/PC350(LC)-11”

PC300-11

PC300-11

With “Quality and Reliability” as the foundation, Komatsu has pursued ever higher levels of quality in environmental, safety and ICT aspects, and released the “PC300(LC)-11/PC350(LC)-11” model to the market, which meets the Non-Road Special Vehicles 2014 Standards. Equipped with the newly developed next-generation engine, this model makes further advances in being clean and efficient.

Fuel consumption rate has been decreased by approximately 5% compared to the previous model(PC300-10).
