Komatsu Europe announces EU Stage V Engines

Komatsu Europe announces the commercial production of new Komatsu diesel engines with EU Stage V technology. Built on Komatsu’s progress in engineering improvements to reduce emissions, EU Stage V will be integrated into Komatsu engines to limit the levels of harmful substances contained in exhaust gas and promote a more sustainable future.

Komatsu consistently engages in the research, development, manufacture and improvement of diesel engines. In-house development and manufacturing capabilities are leveraged for key components, such as hydraulic devices and control systems, in order to reduce environmental impact and to improve fuel economy.

The EU Stage V emissions legislation, applicable throughout all 28 EU member states, is the most stringent to date. In effect for engines below 56 kW and above 130 kW since January 1 2019, it will be applied to 56 to 130 kW engines starting from January 1, 2020.

Komatsu has begun supplying machinery in conformity with EU Stage V emission regulations to customers and new EU Stage V models will be announced when they are launched.

EU Stage V regulations apply to a wider range of engines. It places a limit both on the mass of emitted particle pollution (PM) and on the number of particles (PN) emitted by the engine.

For machines in the 19kW – 560kW power level range to comply with these new PN requirements, a Komatsu Diesel Particulate Filter (KDPF) must be included in the engine’s aftertreatment system. With over 98 percent of KDPF regeneration performed passively, no action is required of the operator, with no interference to machine operation.

Performance remains efficient and costs of ownership low.

Products currently eligible for the Komatsu CARE maintenance programme will continue to qualify under EU Stage V regulations.

As with all Komatsu products and solutions, reliability is assured through a robust design, development, and testing process. EU Stage V systems follow this process and, as a result, retain Komatsu’s position as the industry leader in aftertreatment systems.
