Overview

Perkins 400 Series electric power (EP) engines are the ideal solution if you're looking for reliable, economical power from a compact unit. Our 402 range is the smallest of all. These 0.5 litre, 2 cylinder engines are robust and efficient and can fulfil your power generation needs with minimal operating costs. Engines meet EU Stage IIIA/U.S. EPA Tier 4 interim and the more stringent Tier 4 Final emissions standards. Impressive cold-start capabilities even in the most demanding conditions make them an excellent choice for less regulated territories.

Lower operating costs

The durability of the 402 range, its simple technology, ease of installation and warranty offering all combine to drive down your ownership costs. Oil and filter changes are 500 hours, dependent on load factor, which also trims your costs. As the 400 Series is built on a common engine platform, if you need to upgrade you can do so easily and affordably.

Small packages

When you need power and reliability in even the smallest application, you can trust the 400 Series EP engines to deliver. Our engineers have carefully designed every component to minimise space. Your engine can also be flexibly adapted to make installation and servicing even easier.
