4 Cylinder

The Perkins 400® Series is an extensive family of engines in the 0.5-2.2 litre category. The 4 cylinder 404-22 model sits at the top of the 400 Series engine range. It combines high performance, low operating costs and a compact package – and is the ideal engine for a wide range of off-highway applications.

The 400 Series is a proven family of engines designed to give you optimised performance and robust technology appropriate for the smaller engine sector.

Engines in the series are designed to meet EU Stage IIIA/U.S. EPA Tier 4 Interim as well as the more recent Stage IIIB/Tier 4 Final emission standards.

Compact power

The compact 4 cylinder, 2.2 litre 404-22 provides up to 50 kW (67.1 hp) of power from an engine that is ideal for a wide range of off-highway applications. Its dimensions and ease of installation make it easy to integrate and achieve good service access.

Designed to offer high performance, the 404-22 provides impressive levels of refinement and proven field reliability. A standard 500 hour service interval contributes to low overall cost of ownership. A range of options ensures you have the perfectly tailored model for your applications and markets.

“The 400 Series uses technology that’s appropriate for this sector. It’s about taking proven technologies and using them to get the power density benefits so people can downsize and still get the same performance they need to meet their application.”
James Gardiner, new product introduction marketing manager


Electric power

The 4 cylinder 404 EP range of engines offers a proven, robust solution for customers in the generator set market who are looking for a space-saving solution that meets their specific power requirements.

It’s the most refined member of the 400 Series, offering improvements such as reduced noise, vibration and harshness (NVH). It also offers the same customer benefits as the wider series, such as reliability, cold-start capability, low operating costs, excellent fuel economy and compact, clever design.

The range’s 2.2 litre ElectropaK engines operate efficiently and reliably on prime and standby duty, hitting the key power nodes required by our customers. Some models also provide the flexibility of switching between engine speeds and electrical frequency to meet your specific territory’s needs.

Like other members of the 400 Series family, quiet and dependable operation make it the ideal choice for applications in urban areas where noise is a concern. However, it will perform just as reliably in the most extreme geographic locations, whether it’s seriously hot or bitterly cold. It’s a popular choice as a power generation solution for telecommunications facilities, such as phone masts, particularly in Africa.

“Dependable, reliable and cost effective engines are essential requirements for the power generation market. That's why the world's leading power generation providers continually call on the 400 Series engines to be the heart of their generating sets.”
James Gardiner, new product introduction manager

We worked hard to find a solution when a customer asked us to reduce the low idle speed in their machines while also allowing them to apply full hydraulic load at the lowest idle condition. We delivered this by fitting electronic control to the 400 Series engine.

This not only reduced high and low idle speeds, but because operators could now use their machines at lower speeds, it reduced fuel consumption too.

Traditionally, low-cost diesel engines have mechanical governing, by which the speed of the engine is selected – high to low. The machine applies a load to the flywheel to slow it down and the mechanical governing device introduces fuel to give the torque that balances the load that's applied. The system is entirely mechanical and allows you to select, for example, the engine to maintain 1000 rpm or 2000 rpm.
