Providing EU Stage V for Rental

Learn more about the new EUV Emissions and what it means for your business

What Are EU Stage V Emissions Regulations?

The EU emissions regulations were introduced in 1997 with the purpose of reducing the level of harmful diesel engine emissions for nonroad mobile applications. This legislation introduced limitations on emissions of particulate matter (PM) and nitrogen oxides (NOx), carbon monoxide and hydrocarbons. Since then, a range of stages have been introduced with varying degrees of restrictions.

The latest regulations, Stage V, were introduced in 2019 and aim to further reduce emissions by setting stricter limits on particulate matter and extending the power ranges to which these regulations apply. The new regulations will now also cover the smallest (<19kW) and largest (>560 kW) engines, setting a minimum stringency over the entire power range.


Introducing FG Wilson rental product range

Throughout 2021 into 2022 FG Wilson will be introducing our new fleet of EUV compliant PRO models. These will range from 20 up to 550 kVA to ensure the needs of rental customers are met. During May and July of this year you will see the introduction of the PRO200-4 and PRO310-4 models which are powered by the Perkins 1206 (200 kVA) and 1706 (310 kVA) engines. Leading into 2022 you can then anticipate the introduction of three more models at 20, 100 and 550 kVA.

The PRO Range has a wealth of additional features which ensures all rental requirements are met for use within any environment. Our rental generator sets are fuel efficient, easy to operate and fully robust to meet the specific criteria of your temporary power needs. Our fully sound attenuated enclosures have excellent noise reduction making them suitable for residential projects, events and a wide range of other applications. Alongside this, the generators operate efficiently in all elements from -4 up to 43C and offer 50/60Hz switchability to support all applications and locations. This ensures our PRO Range will successfully fulfil your requirements irrespective of your location across the globe. 



How does EUV legislation impact the exhuast treatment process?

Electronic Common Rail

Very high-pressure fuel is delivered to advanced electronically controlled injectors. This delivers a ultra fine spray of diesel which enhances the combustion process making it more efficient. This provides you the customer with improved power, torque and a better cold start and reponse.

Cooled Exhaust Gas Recirculation

A small proportion of the exhaust gas is initially cooled and then fed back into the engine inlet. This process results in less oxygen in the cylinder, which in turn results in less NOX being created in the combustion. This proven technology has been used in the automotive industry for many years to great effect. The intelligent EGR valve is capable of controlling the amount of gas recirculated dependent upon the different operating conditions



Diesel Oxidation Catalyst

The diesel oxidation catalyst (DOC) is an aftertreatment component with a flow-through substrate coated with a high-performance catalyst and housed within a stainless steel canister. By passing exhaust fumes through the catalyst it can convert carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water.

Diesel Particulate Filter (DPF)

Exhaust gas passes through the walls of ceramic lattice (wall-flow device), trapping 85% or more of soot particles / particulate matter (PM).  The soot particles collected in the DPF are then burned off through a process of regeneration.   


Selective Catalytic Reduction

A fine spray of AdBlue solution is mixed with exhaust gases. A special ceramic catalyst uses this solution to convert nitrogen oxide NOX into nitrogen and water.

AdBlue is a colourless liquid made up of high-purity urea (32.5%) and deionised water (67.5%)


Thermal Management of Aftertreatment

Thermal management of the aftertreatment is very important. A DPF requires raised temperatures for the regeneration process to burn of soot particles.  Additionally, the selective catalytic reduction process requires raised temperatures for the catalytic reaction and to remove urea deposits.
