History of Perkins Engines - Perkins 400 Series

A History of the Perkins 400 Series Engines

The Perkins 400 Series is a key chapter in the history of Perkins Engines, representing a modern, efficient, and compact range of diesel engines designed to meet the demands of the 21st century. Launched in the late 1990s and continually developed in subsequent years, the 400 Series was aimed at applications requiring smaller engines with high performance, low emissions, and excellent reliability. The series quickly became a popular choice for compact machinery and industrial equipment, earning a reputation for efficiency and dependability.

Development and Launch

By the 1990s, the demand for smaller, more fuel-efficient engines was on the rise, driven by stricter emissions regulations and the growing market for compact machinery. The Perkins 400 Series was developed to address these requirements, replacing older engines such as the Perkins 100 Series. This new range offered improved performance, reduced emissions, and enhanced durability while maintaining the quality and reliability associated with Perkins.

Manufactured at Perkins’ facilities in Peterborough, UK, and other global locations, the 400 Series was designed to cater to a wide variety of applications, particularly in industrial, agricultural, and construction sectors.
