Tier 4 Fuel Duel

Cummins Fuel Duel - Proving Up To 5% Higher Fuel Efficiency For Tier 4 Interim / Stage IIIB.

Cummins will give you the lowest cost of operation and we’ve completed the tests to prove it. 

Our Tier 3 and Tier 4 Interim 6.7-liter QSB engines installed in identical front end loaders competed back-to-back in a Fuel Duel test confirming a 5% fuel efficiency improvement for the Tier 4 Interim 6.7-liter QSB installation. 

The improved fuel efficiency of the Tier 4 Interim engine was achieved without compromising machine performance.  In fact, the Tier 4 Interim QSB6.7 powered machine completed the Fuel Duel tests in shorter cycle times due to faster engine response to load demands.  This proves that our fully optimized installation is a key enabler to providing improved machine performance.

With 5% lower fuel consumption; your Tier 4 Interim machine could reduce CO2 greenhouse gas emissions by up to 5 tons every year.

All Cummins Tier 4 engines 75 horsepower and above are ready to operate on B20 biodiesel fuel, so you can also help to reduce CO2 emissions by using this alternative fuel.  For more information on operating Cummins engines with B20 Biodiesel Blends please see our B20 FAQ.
