EU emission standard
Diesel generators
Stage V
Stage V is the strictest EU emission standard for non-road mobile machinery. Whether it applies to your generator depends on the machinery category, application and placing-on-market rules — not every installation is affected.
EU emission standard
What is the Stage V standard
Stage V is the current European emission standard for engines used in non-road mobile machinery, including generators. It builds on Regulation (EU) 2016/1628 and sets strict limits for NOx, particulate matter (PM) and other pollutants.
Stage V is defined for non-road mobile machinery (NRMM) — machines not operated on public roads. The regulation governs placing machinery on the EU market: whether and when Stage V applies to a specific generator depends on the machinery category, the application and the rules for placing that type on the market. For stationary installations outside the NRMM regime, local rules may apply.
Compliance is typically achieved with exhaust aftertreatment such as a diesel particulate filter (DPF) and SCR catalytic reduction. The exact configuration is engine- and model-specific.
How Stage V compliance works
Diesel engine
Prime mover of the generator set
Emission limits Stage V
NOx, PM limits per EU 2016/1628
Aftertreatment
DPF filter, SCR catalytic reduction
Compliant exhaust
Emissions within EU limits
The exact aftertreatment configuration depends on the engine and generator model. We confirm applicability and availability individually per project.
Applications
Where Stage V generators are used
Stage V generators are most often a factor in mobile and outdoor applications, where EU legislation, the machinery category or the conditions of a specific project call for them.
Construction sites
Temporary site power for cranes, compressors and site cabins — Stage V typically concerns mobile machines, always per category and project conditions.
Event power
Temporary power supply for events, productions and public gatherings with strict requirements for noise and emissions.
Rental & fleet
Rental companies and equipment fleets need machines meeting the requirements of different projects and access zones.
Urban & sensitive zones
Work in cities and sensitive areas where clients or authorities set emission requirements for machinery. Access conditions are defined by the specific project, not by Stage V alone.
Technologies
Technologies behind Stage V compliance
Stage V compliance is typically achieved with modern engine management and exhaust aftertreatment. The exact configuration is specific to the engine and generator model.
Diesel particulate filter (DPF)
Traps solid particulates from exhaust gas — a key element in meeting Stage V particulate limits.
SCR catalytic reduction
Reduces nitrogen oxides (NOx) using AdBlue/urea dosing — required by many Stage V engine configurations.
Aftertreatment scheme
Engine
Combustion and exhaust gas
DPF filter
Particulate matter capture
SCR catalyst
NOx reduction with urea
Exhaust Stage V
Emissions within EU limits
Our offer
Stage V generators in our offer
We supply diesel generators in Stage V configuration from manufacturers with certified engines. Stage V availability is confirmed individually per model; selection accounts for power rating, application and the project's emission requirements.
