Komatsu introduces Stage 5 Engines on all forwarders
The Komatsu 825TX, 835TX and 845 models are all upgraded with a Stage V diesel engine. The new engine installation offers many benefits, such as an all-new AdBlue system, a new exhaust system and hydraulic valve lifters.
The AdBlue system has been completely revamped, with a focus on improvements to increase dependability. The tank has been moved to the front-left storage space and has also been improved with a new filling solution incorporating both a spill guard and filtration. It even has a specially designed funnel with venting channels for faster filling. All these factors simplify the machine’s daily maintenance needs.
All these factors streamline the machine’s daily maintenance needs.
The EU Stage V emissions legislation, applicable throughout all 28 EU member states, is the most stringent to date. It has been in effect for engines below 56 kW and above 130 kW since 1 January 2019 and was applied to 56 to 130 kW engines starting from 1 January 2020.
EU Stage V rules place 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 energy level range to comply with these new PN requirements, a Komatsu Diesel Particulate Filter (KDPF) must be included in the engine’s after-treatment system.
