QSK50 Tier 4 Dual Fuel Engine
Optimizing Productivity
The industry’s greatest diesel savings
We’re going to give it to you straight — just like we always have. When it comes to diesel savings with dual fuel, substitution rate is important. But it’s not everything. Many factors contribute to overall fuel savings, including diesel efficiency, natural gas usage and engine speed. With the QSK50 T4 Dual Fuel engine, we’ve carefully balanced all these factors to deliver not only a high substitution rate, but also the industry’s greatest fuel savings.
Optimizing Savings
There’s no substitute
Our EPA Tier 4 Final-certified QSK50 Dual Fuel solution provides a maximum substitution rate of 70% at the ideal operating range of 1,500–1,950 rpm. Combined with our unique combustion recipe, the QSK50 T4 Dual Fuel can maximize diesel savings at a rate unmatched by anyone else in the market today.
Diesel saved per hour, per unit:
370 L / hr - 113 L / hr = 257 L / hr saved per unit*
Diesel saved per year (2,000 pumping hours), per unit:
257 L / hr x 2,000 hrs = 514,000 L / year saved per unit*
