Komatsu’s hydraulic excavators offer the latest Tier 4 technology with plenty of power and exceptional sustainability. To protect people and the environment, a significant reduction in harmful emissions in the exhaust tract has been achieved. The exhaust after-treatment system, which utilizes diesel exhaust fluid (DEF), reduces nitrogen oxide (NOx), facilitates easier servicing of emissions components, and enables the engine to meet US EPA Tier 4 emission standards and the European EU V regulation. The new configuration includes an SCR catalyst assembly and an additional DEF tank near the exhaust system.
