Cummins recently announced，Approved the use of unblended paraffin fuel in its full range of high horsepower diesel engines（Fuel matchEN15940 standard），The fuel is a mixture comprise hydrogenated vegetable oil,（HVO）Including renewable diesel.。Compared to using conventional diesel fuel，UseHVOSuch renewable diesel can be reduced by up to 90 percent%Of greenhouse gases（GHG）Discharge，Final data depends on specific fuel footprint。

This license applies to high horsepower.（19L-95L、V903、ACE）Engine，Applications include mines、Ship、Railways and oil and gas fields。At present, all industrial engines sold by Cummins can directly use 100%Renewable diesel，Or use a mixture of renewable diesel and conventional diesel in any ratio，And engine modification is not require.。Provided that the renewable diesel used must be CEN compliant（CEN）PrescribedEN15940 standard。

Cummins Vice President, Power Systems EngineeringGary JohansenExpress：

We are committed to working with our customers to achieve carbon neutrality，Alternative fuels as a solution，Critical for decarbonization of existing equipment。Approval to use unblended renewable diesel in all high horsepower engines，It is an important step for our continuous innovation.，Help our industrial customers reduce their carbon footprint while ensuring product performance and reliability。

Prior to the publication of this bulletin，Cummins allows industrial high horsepower engines to use blends up to 25 percent%Renewable diesel fuel，Railway use is allowedQSK95 Engine use 100%Renewable diesel。In addition，In the fourth quarter of 2021, Cummins first introduced 100 to the market.%Backup generator using renewable diesel fuel.，Power for data centers and other critical applications。

Current technology assessments for high-horsepower engines using renewable diesel include：Discharge cycle test、Performance testing、Transient test、Fuel consumption testAndRoad test。

The test shows that，Without changing the engine hardware and software，Engine exhaust emissions are comparable to those of conventional diesel.，And meet that requirements of the US environmental protection agency.（EPA）Standard。The test also showed that，Renewable diesel can be a direct replacement for conventional diesel.，The specific performance is：

Greenhouse gases from oil well operation（GHG）90% reduction in emissions%

Reduce exhaust emissions of particulate matter and soot by 50 percent%

There are about 1-2%Power loss of（Experience points）

Does not affect service/Maintenance interval

Can be stored for a longer time

Unblended is now approved for useHVOThe Cummins high horsepower engine platform includes：For use in the industrial fieldQSK19、K19、QSK23、QST30、QSK38、K38、QSK45、QSK50、K50、QSK60、QSK78、QSK95、V903 andACE。

Cummins continues to innovate，Take the lead in using 100 on industrial high-horsepower engines%Renewable diesel，Promote industry emission upgrading with advanced technology。ThroughPlanet Plan 2050，Cummins Pledges to Actively Address Climate Change，Help improve the community environment and make rational use of resources。
