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.
