Stage V Engine now on all Komatsu forwarders

The Komatsu 825TX, 835TX and 845 models have all been upgraded with a Stage V diesel engine. The new engine installation offers many advantages, such as an all-new AdBlue system, a new exhaust system and hydraulic valve lifters. Source: Timberbiz

The AdBlue system has been completely overhauled, with a focus on improvements to increase reliability.

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.

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 regulations 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 power 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.
