Perkins 3 400D Series engines

Tier 3 400D Series engines from Perkins offer the same package size and performance and power density of the Tier 2 predecessors. Noise reductions have improved up to 3 dB(A), with the option of lowering noise levels by an additional 2 dB(A) with a non-standard low-noise fan. Ratings range from 40 to 67 horsepower. The company has improved engine cooling, resulting in smaller cooling packages. Perkins invited 37 editors from around the globe to its launch of the 400D series.
