Diesel engine 404J-22G

4-cylinderwater coolingStage V

Overview The Perkins 400 Series compact engine family is engineered for generator set applications. The 404J-22G is designed to meet EU Stage V emissions while delivering consistent mechanical performance and ease of integration for mobile and stationary gensets.

Key Specs (summary)

• Gross Mechanical Output: 18.6-20.6 kWm
• Typical Electrical Output: 20.1-22.3 kVA (16.1-17.8 kWe)
• Rated Speed: 1500 rpm
• Emissions: EU Stage V

Features At A Glance

• Reliable cold and hot starting with stable steady-state and rapid transient response, optimised for generator set duty cycles.
• Compact footprint and straightforward maintenance: spin-on filters and cassette-type fuel injection pump options simplify service and integration.
