What are the European Stage V emissions regulations?
European emissions regulations were introduced in 1997 with the aim of reducing the level of harmful emissions from diesel engines in non-road mobile applications. This legislation introduced limits on emissions of particulate matter (PM) and nitrogen oxides (NOx), carbon monoxide and hydrocarbons. Since then, a series of phases have been introduced with varying degrees of restrictions.
The latest regulations, EU Stage V, were introduced in 2019 and aim to further reduce emissions by setting stricter limits on particulates and extending the power ranges to which these regulations apply. The new regulations will now also cover the smallest ( 560 kW) engines, setting minimum stringency across the entire power range.
How does EURO V legislation affect the exhaust gas treatment process?
Electronic common rail
Very high pressure fuel is delivered to advanced electronically controlled injectors. This produces an ultra-fine jet of diesel that improves the combustion process and makes it more efficient. As a customer, you benefit from improved power and torque, as well as better cold starting and responsiveness.
EU Stage V Electronic Common Rail
Cooled exhaust gas recirculation
A small proportion of the exhaust gases is initially cooled and then re-injected into the engine intake. This process reduces the amount of oxygen in the cylinder, which in turn reduces the creation of NOX during combustion. This proven technology has been used in the automotive industry for many years with great effectiveness. The intelligent EGR valve is able to control the quantity of gas recirculated according to different operating conditions
EU Stage V EGR
Diesel oxidation catalyst
The Diesel Oxidation Catalyst (DOC) is an aftertreatment component with a through substrate coated with a high performance catalyst and housed in a stainless steel cartridge. By passing exhaust gases through the catalyst, it can convert carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water.
ox EU Stage V diesel catalyst
Diesel particulate filter (DPF)
Exhaust gases pass through the walls of the ceramic mesh (wall flow device), trapping 85 % or more of soot particles / particulate matter (PM). The soot particles collected in the DPF are then burnt by a regeneration process.
DPF EU Stage V
Selective catalytic reduction
A fine spray of AdBlue solution is mixed with the exhaust gases. A special ceramic catalyst uses this solution to convert nitrogen oxide NOX into nitrogen and water.
AdBlue is a colourless liquid composed of high purity urea (32.5 %) and deionised water (67.5 %).
AdBlue EU Stage V
Thermal management of post-treatment
Thermal management of post-treatment is very important. A DPF requires high temperatures for the regeneration process to burn off the soot particles. In addition, the selective catalytic reduction process requires high temperatures for the catalytic reaction and to eliminate urea deposits.
Transition from EU phase IIIA to EU phase V
Late 1997, European legislation has begun to implement regulations on emissions from non-road mobile machinery. These regulations apply to primary or backup power used in mobile applications, including drills, construction wheel loaders, bulldozers, road excavators, forklifts, aerial work platforms, mobile cranes and other non-road equipment, including mobile generators. Over time, regulations have become progressively stricter with the aim of further reducing harmful substances in engine exhaust gases, in particular carbon monoxide, hydrocarbons, particulate matter (PM) and nitrogen oxides. The standards have moved on from the initial phase to the current phase V, also known as the EU 2016/1628.
The additional equipment and complexity needed to meet the updated requirements of Phase V present new challenges for the European electricity rental market. Since legislation for mobile generators has ignored Phases IIIb and IV, a major technological leap is required, including engine modifications and off-engine after-treatment. For example, a diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) are required for all high-pressure fuel system units over 19 bkW, while selective catalytic reduction (SCR) will be required for all units over 56 bkW.
SCR requires a diesel/diesel emission fluid.Ad-Blue to convert nitrogen oxides (NOx) into harmless compounds. Although AdBlue is a common fluid in automotive and mechanical applications, it is an additional consideration for a rental power operator who may be operating in a remote location. The EU Stage V standard also extends the scope to a wider range of motor types and sizes, regulating for the first time motor powers in excess of 560 kW, which presents challenges in terms of motor availability for the large mobile power generation market. In addition to technical issues, there are commercial challenges as rental operators struggle to increase rental rates to offset significant increases in product acquisition costs and maintain acceptable financial returns.
The changes introduced by the EU Stage V standardstandard, as well as the proposed new particle number (PN) limits, effectively require the use of diesel particulate filters (DPFs) to reduce emissions to compliance levels for engines covered by the EU Stage V.
At very high pressures, electric common rail applications feed fuel to electronically controlled fuel injectors. This process produces a very fine jet of diesel that produces tiny soot particles that are a potential health hazard. Although this type of system allows complete control of the combustion process and enables thermal management of after-treatment systems, the particulates must be managed to comply with emissions regulations.
A filtration system DPF is designed to reduce particulates, including soot, from diesel engine exhaust. A series of alternately blocked channels force the exhaust gases through the walls of the channels where the particulates are physically captured in the filter. Many rental generator applications have low load factors or use oversized equipment due to limited information on the customer's load profile or high start-up loads with relatively low operating loads. In low load operation, a FAP will accumulate particulates due to low exhaust temperatures if the rate of soot deposition is greater than the rate of passive regeneration of the hot exhaust gases, resulting in an increase in engine back pressure. As the back pressure increases, the particulates must eventually be removed from the exhaust. FAP by a process called regeneration.
By managing the regeneration processes internally, with intelligent measurement of the soot level in the DPFS and integrated thermal management, FG Wilson's high-speed system works without any operator interaction. This allows all rental gensets equipped with FAP systems to be used flexibly in any application and any environment. FG Wilson generator sets carry out this process seamlessly for the operator, without the need to take the genset offline or add load banks and other equipment that increase complexity, cost and weight. We can guarantee that all the EU Stage V packages our customers receive are fully integrated and tested for optimum performance and ease of use.
To facilitate this change, however, FG Wilson is following the integrated transition structure of the regulations, to continue manufacturing equipment using the previous emission level for 18 months after Stage V comes into force. There is also a six-month tolerance for generators sold after the 18th month of manufacture. Phase V came into force on 1 January 2019 for all engines under 56 bkW and over 130 bkW. For engines in the 56 to 130 bkW range, the effective date is 1 January 2020. By increasing their EU Stage IIIA-compliant fleet before the legislation comes into force, fleets can maintain lower rental rates for their customers and reduce overheads.
On the other hand, the first users of EU Stage V-compliant machines will benefit from very favourable rental conditions.
These products are only available to order.
Durability with FG Wilson
The use of low carbon footprint fuels supports FG Wilson's sustainability initiatives and celebrates FG Wilson's commitment to acting responsibly and thinking sustainably for a better future.
Renewable fuels are derived from renewable resources such as planted crops. Considered to be low-carbon, these fuels, whether 100 % or blended, can be used as direct substitutes for diesel fuel and can be used to reduce the carbon footprint of diesel engines on the basis of a life-cycle analysis.
The benefits of renewable and low-carbon fuels include* :
- No specific engine conversion process is required when these fuels are used for the first time or subsequently.
- They are compatible with the filters and engine oils used with conventional diesel fuels. No impact on service intervals is expected. In general, it is recommended that oil change intervals be based on oil analysis.
- They can be stored in the same tanks as diesel fuel and have a similar lifespan to diesel fuel.
*Please see our PDF brochure for a full introduction and guidelines on the use of low-carbon fuels.
