All Kohler diesel-fueled engines are approved to use HVO in the United States, in line with ASTM D975 standard. This confirmation comes just a few months after European compliance was announced. In February, in fact, Kohler had announced approval to use HVO for all its diesel engines in
Europe, in line with the EN15940 standard.
The use of HVO, hydrotreated vegetable oil, whether pure or blended with conventional diesel, does not require any specific engine modifications or upgrades. However, exhaust gas aftertreatment system remains necessary where already provided.
Unlike conventional biofuels that take resources away from agriculture and contribute in part to deforestation, HVO is a renewable fuel that can be produced from various vegetable oils and fats: it is derived from biological waste and, free of fossil-derived oils, is a 100% recycled product. In addition, depending on the raw material used in its production, it leads to a reduction in overall CO2 emissions of up to 90%. Engine exhaust emissions also benefit directly, given the very low sulfur content. For more, visit kohlerengines.com.
