Diesel engine 404D-22TAG

4-cylinderturbochargedin-line

Overview
The Perkins 404 range of electric power (EP) engines is the largest, most refined member of the 400 Series. The 4-cylinder 2.2 litre 404D-22TAG provides reduced noise, vibration and harshness (NVH) while delivering reliable performance for generator sets in unregulated, UN ECE R96 Stage IIIA constant speed and U.S. EPA Stationary Emergency Engine territories. Key user benefits include reliable cold-start capability, low operating costs, compact design and good fuel economy.

Key specs

• Gross mechanical output: 34.4-36.3 kWm
• Typical electrical output: 37-40 kVA (29-32 kWe)
• Emissions: UN ECE R96 Stage IIIA constant speed; U.S. EPA Stationary Emergency Engine

Features at a glance

• Low lifetime operating cost — Reliability, efficient fuel consumption, straightforward installation and proven components reduce total cost of ownership. Optional aftertreatment for further cost savings is available.
• Compact, quiet and suitable for noise-sensitive sites — Delivers 20-40 kVA range with 4-cylinder refinement and reduced noise, supporting urban and other noise-sensitive generator installations.
