Baudouin Stage V Engines: High Performance and Environmental Compliance

Stage V engines are at the heart of European efforts to reduce pollutant emissions from non-road mobile machinery and inland waterway vessels, guided by stringent European Union standards.  They represent a significant step forward in emission reduction, enhancing air quality across industries.

What is a Stage V engine?

Stage V engines is designed to meet the most stringent emissions standards set out in European Directive 2016/1628/EC. These engines are manufactured to drastically reduce emissions of:

  • Nitrogen oxides (NOx)
  • Carbon monoxide (CO)
  • Hydrocarbons (HC)
  • Particulate matter (PM)
  • Particulate number (PN)

Requirements for Stage V engines

To comply with Stage V, engines must meet specific emission limits for the listed pollutants. Manufacturers must use advanced technologies such as SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filter) to meet these requirements.

 Impact of Stage V regulations on industries

The implementation of Stage V regulations is having a considerable impact on a number of industries:

Emissions reduction in Agriculture industry


Tractors and other agricultural equipment must now use Stage V-compliant engines, reducing their environmental impact.

Important to comply with regulation in the construction industry for a greener environment.


Construction machinery such as excavators and bulldozers must also comply with these standards, contributing to a cleaner working environment.

Energy is a challenge for emissions reduction, that's why it's important to comply with Stage V.


Mobile generators must be fitted with Stage V engines to reduce emissions in temporary or mobile use.

 Inland waterway application must comply with European norm for a greener world and protect ecosystem.

Inland Waterway

Engines in pleasure craft, commercial vessels, and inland waterway boats must meet Stage V standards to reduce emissions and improve air and water quality.

Advantages of Stage V engines

Stage V engines offer a number of benefits.

The reduction of emissions has been demonstrated to result in a significant decrease in the levels of NOx, CO, HC, and PM, which collectively contribute to an improvement in air quality and a healthier environment, enhancing the overall quality of life.

Regulatory compliance ensures that companies meet European regulations and avoid penalties. Furthermore, the technologies employed to achieve Stage V standards frequently result in enhanced energy efficiency of engines, which in turn leads to reduced fuel costs.

Technologies used in Stage V engines

In order to comply with the stipulations of Stage V, engines have been equipped with a number of sophisticated technologies. Selective Catalytic Reduction (SCR) employs a reducing agent to transform nitrogen oxides into nitrogen and water, thereby effectively reducing NOx emissions. Diesel particulate filters (DPFs) trap fine particles in the exhaust gases, preventing their release into the atmosphere.

Exhaust Gas Recirculation (EGR) reduces combustion temperatures by recirculating a portion of the exhaust gases back into the engine cylinder, thereby reducing NOx emissions. Furthermore, direct injection and advanced electronic controls facilitate optimal fuel combustion, thereby minimising emissions and maximising engine efficiency.

Baudouin has developed engines that comply with Stage V for rental and mobile applications.

Stage V rental and mobile power generations engines

We are proud to announce that we have developed and are now the only company to offer a dedicated 1MW rental engine that can be fitted into a 20″ container. Unlike existing solutions, which require 2 x 500kWe engines in a container, our innovative design provides a more efficient and powerful option.

Our engines, including the 6M33 and 12M33 models, deliver peak power from 500kWe to 1MWe, meeting the most demanding operational requirements. Additionally, we achieve these standards with a very compact SCR and without the need for a DPF, ensuring compliance with Stage V requirements for power generation engines in mobile and rental applications.

These engines can:

Reduce NOx by up to 92%

Reduce particulates by up to 78%

Reduce emissions by up to 98%
