New Tier 4 Final G-drive engines from Cummins Power Generation

Cummins Power Generation launched two new diesel G-drive engines from 240-433 horsepower that are certified to meet EPA Tier 4 Final emissions regulations for nitrogen oxides (NOx) and particulate matter (PM or soot) without the use of a Diesel Particulate Filter (DPF). Instead, the new engines employ a combination of in-cylinder combustion improvements, exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) exhaust aftertreatment. These new engines are suitable for powering generators from 150-300kVA.

The first Tier 4 Final G-drive engines, available Q2 2014, will be the QSB7 and QSL9. The QSB7 is rated at either 240 or 315 horsepower and designed to power generator sets with standby ratings of 150-220 kVA. Available at the end of Q2 2014, the QSL9 will be rated at 433 horsepower and designed to power generator sets rated at 300kVA.

"By eliminating the need for a DPF, these engines offer reduced maintenance and 4 percent better fuel efficiency than previous Tier 3 engines," said George Iarca, regional manager for G-drive, Cummins Power Generation. "Our next-generation aftertreatment systems are optimized for each engine size and simplify engine packaging without increasing cooling requirements. High-pressure fuel injection, advanced turbocharging and enhanced electronic engine controls permit these engines to deliver the power and performance that our customers have come to expect from Cummins Power Generation."

The Tier 4 Final G-drive engine packages will also include diesel exhaust fluid (DEF) dosing and supply modules that control the dispensing of DEF into the SCR to cut emissions of NOx. Equipment manufacturers will need to supply the DEF tank and fluid-handling accessories, as these items tend to be sized to complement fuel tank size and intended runtimes for the final generator set package. The normal consumption of DEF is about 4 percent of fuel consumption.

"These new G-drive engines are the result of more than two years of design engineering and real-world field testing," said Iarca. "Cummins developed solutions to meet customer concerns and tested the design results under real-world operating conditions in the field. The result is a proven line of new Tier 4 Final G-drive engines that are economical to operate, quiet and clean, and that deliver the power, performance and reliability that generator builders need."
