Diesel engine 404D-22G

4-cylinderin-linefor generator sets

Overview
The Perkins 404 range of electric power (EP) engines is the most refined member of the 400 Series for generator set applications. The 4-cylinder, 2.2 litre 404D-22G delivers reduced noise, vibration and harshness (NVH) while offering reliability, cold-start capability, low operating costs and compact design suitable for unregulated, UN ECE R96 Stage IIIA constant speed and U.S. EPA Stationary Emergency Engine territories.

Features At A Glance

• A lifetime of low cost — Reliability, excellent fuel economy, simple installation and proven components minimise total cost of ownership. Cost-saving aftertreatment options are available.
• Powerful, quiet and refined — Provides typical 20–26 kVA generator output with the refinement and noise reduction of a 4-cylinder layout; suitable for installations where acoustic performance is important.
