Perkins introduces its Tier-4 Interim 1200 Series engines. At the top of the range is a 7-liter, 6-cylinder engine capable of 225 kW. This represents a 21-percent increase in power output over Perkins’ current 5.5-liter offering, giving customers who may have chosen a larger engine previously, the choice of the same power from a smaller engine package. The 1206E-E70TTA (pictured) has two turbochargers — one small, one large, mounted in a series. The smaller first-stage turbo accelerates quickly for good response and torque at low speeds; the larger second stage provides the high airflow required to provide class-leading power density.
