Company History and Overview
Perkins Engines Company Limited, founded in 1932 in the United Kingdom, has become one of the world’s leading manufacturers of diesel engines, especially known for powering heavy equipment across industries such as construction, agriculture, power generation, and industrial sectors. Now part of Caterpillar Inc., Perkins has built a reputation for producing durable, efficient, and versatile diesel engines catering to a broad spectrum of applications.
Design Philosophy and Engine Series
Perkins engines are engineered for reliability, ease of maintenance, and fuel efficiency. Their modular approach allows customization to fit specific needs across equipment types. Popular series include the 400, 900, 1100, 1200, and 1500 families, ranging from small compact engines used in skid-steers and generators to large multi-cylinder units delivering hundreds of horsepower for heavy construction and agricultural machinery.
Key Perkins Engine: The 4.108 Model
One widely recognized model is the Perkins 4.108 engine, valued for its compact size and robust performance. With a displacement of about 1.8 liters and power output ranging from 38 to 51 horsepower depending on configuration, this four-cylinder turbocharged diesel engine suits equipment requiring compactness without sacrificing reliable power.
It is praised for fuel efficiency, emissions compliance, and adaptability. Variants allow modifications in fuel pumping systems and air intake to suit specific operational requirements.
Performance Features
Perkins engines are found in a multitude of heavy equipment types:
Maintenance and Longevity
Routine maintenance such as oil and filter changes, coolant monitoring, and regular inspection of fuel and air systems are crucial for maximizing Perkins engines’ service life. Their straightforward design often simplifies servicing even in field conditions, reducing downtime.
OEM parts are recommended to ensure compatibility and performance. Perkins offers extensive technical support and parts availability globally.
A Small Story
A construction company operating a fleet of compact loaders equipped with Perkins 4.108 engines reported exceptional fuel economy and reliability over several years. Despite intense daily usage on uneven terrain, engines required only scheduled maintenance without major repairs. Operators appreciated the smooth power delivery and easy access to service points, contributing to high productivity and low operating costs. This reliability enhanced overall project efficiency and cost control.
Terminology
Perkins diesel engines, exemplified by models like the 4.108, provide a blend of durability, power, fuel economy, and regulatory compliance tailored to heavy equipment needs. Their adaptability across a broad horsepower spectrum and proven reliability have established them as trusted companions in construction, agriculture, and industrial sectors worldwide. Proper maintenance and understanding of engine features ensure operators maximize performance and longevity, supporting continuous, productive operations.
