Cummins QSB3.3 engineWith a power range from 80 to 110 horsepower, Cummins' QSB3.3 engine meets Tier 3 and is the first industrial engine of its size to incorporate full-authority electric controls and a High Pressure Common Rail fuel system, says Cummins. The QSB3.3 engine evolved from the B3.3 platform, and the top-rated 110-hp QSB3.3 engine achieves the same fuel efficiency as the 85-hp B3.3 engine at Tier 2. The HPCR fuel system enables high-pressure fuel injection from 11,600 to 16,000 psi to be maintained independent of rpm.
