As well as offering a broad range of engines which meet the stringent EU Stage V and U.S. EPA Tier 4 Final emission standards, Perkins’ long-standing commitment to sustainability and support for customers during the energy transition to a lower-carbon future means its engines have for many years been capable of running on a range of renewable and low carbon intensity fuels1.
Renewable fuels are derived from renewable resources such as planted crops (soy, palm, rapeseed, etc.), used cooking oil, animal fat, biomass, algae, and others. They reduce the carbon footprint of diesel engines on a Life Cycle Analysis basis. Renewable fuels that are derived from fats and oils may be processed through hydrotreating. The result is a high paraffinic renewable diesel (RD), also called hydrotreated vegetable oil (HVO), that can be used in diesel engines.
The performance of HVO is similar to regular diesel, but it reduces the carbon footprint associated with operating the engine and can lower nitrogen oxide (NOx) and particulate matter (PM) under certain conditions. Its chemical similarity to diesel means that the machine’s power output and uptime are not compromised when introducing HVO as an alternative, and it can also be blended with diesel.
Biomass and syn gas can also be converted into liquid fuels through various processes and their products are typically know as biomass-to-liquid (BTL) or gas-to-liquid (GTL). Depending on the original feedstock these products maybe renewable. BTL, GTL and HVO have similar chemistries and performance specifications, and all can be used in diesel engines.
Low carbon intensity (LCI) fuels are typically paraffinic hydrocarbons, hence these fuels, whether at 100% or blended, can be used as drop-in replacements for diesel fuel. These fuels have many benefits:
To be applicable for Perkins’ diesel engines, it’s recommended that renewable and low carbon intensity fuels meet the latest version of any of the following specifications:
Renewable and low carbon intensity fuels that meet the requirements listed above can be used at:
Here’s some guidance and potential impacts for the use of renewable and low carbon fuels according to the specifications detailed above:
The use of fuels with low carbon footprints supports Perkins’ sustainability initiatives.
Perkins is continuously following the development of renewable and low carbon intensity fuels, and is involved in the development of appropriate specifications to ensure the successful application of these fuels in Perkins engines.
1 Contact your Perkins distributor or reference your engine’s Operation and Maintenance manual to confirm the fuel compatibility and specification requirements for your engine.
2 See your engine’s Operation and Maintenance manual for specific biodiesel limits on your engine.
