The History of Cummins

Powering the Future, Rooted in Innovation

At GFE Power Products, we take pride in offering only the most reliable, high-performance diesel generators, and many of those feature engines from one of the most respected names in power: Cummins. Known for unmatched reliability, innovation, and global presence, Cummins engines have powered everything from hospitals and data centres to remote construction sites and critical infrastructure. But how did Cummins become such a globally dominant force in power generation?

A Legacy That Began in a Garage: The Founding of Cummins

Cummins Inc. was founded in 1919 in Columbus, Indiana, USA by Clessie Lyle Cummins, a self-taught mechanic and innovator. While diesel engines were primarily used in marine and industrial settings at the time, Cummins saw their potential for broader commercial applications.

Key Milestones in the Early Years

• 1919: Cummins Engine Company is founded with the financial backing of W.G. Irwin, a local banker.
• 1929: The first diesel-powered American automobile crosses the country, driven by Clessie Cummins himself.
• 1930s: Cummins engines begin gaining traction in the trucking and rail sectors.
• 1940s: During WWII, Cummins engines are used extensively in military and logistics operations, proving their durability under pressure.

What began as an experiment in a machine shop quickly became a global revolution in diesel technology.

Cummins Through the Decades: Innovation and Expansion

1950s–1970s: Heavy-Duty Dominance

Cummins became synonymous with reliable, heavy-duty diesel engines during the post-war economic boom. The company focused on:

• Developing large-displacement diesel engines for trucks and generators
• Building global production facilities
• Improving fuel injection and combustion efficiency

By the late 1970s, Cummins had a stronghold in the transportation, marine, construction, and power generation industries.

1980s–1990s: Power Generation and Emissions Control

With tightening emissions regulations, Cummins pivoted toward cleaner diesel technology. Their engines became more efficient, quieter, and environmentally friendly, perfect for standby and prime power generators.

Breakthroughs during this time included:

• The introduction of electronic engine control units (ECUs)
• Advanced fuel injection systems
• Turbocharging and aftercooling for improved performance

This era also saw Cummins expand its global generator division, creating turnkey solutions for emergency backup and off-grid applications.

Cummins Engines Today: Powering Modern Demands

Now operating in over 190 countries, Cummins is a global leader in:

• Engine manufacturing (diesel, natural gas, and hybrid systems)
• Power generation
• Electrification and hydrogen technology
• Emissions solutions and filtration systems

What Makes Cummins Engines Exceptional for Generators?

At GFE Power Products, we choose Cummins engines because of their:

• Unmatched reliability in harsh environments
• Long service intervals and low maintenance requirements
• Excellent fuel economy
• Quiet operation with advanced noise-reducing technologies
• Compliance with international emissions standards, including EU Stage V and Tier 4 Final

Inside a Cummins Engine: What You’re Really Getting

Cummins engines are engineered for optimal efficiency, power density, and longevity. These key technologies set them apart:

• Advanced Fuel Injection Systems: Cummins engines often use high-pressure common rail (HPCR) fuel systems, which:
  • Deliver precise fuel quantities
  • Optimise combustion
  • Reduce emissions
  • Improve cold starts
• Turbocharging with Aftercoolers: Turbocharged Cummins engines generate more power without increasing size. Aftercoolers:
  • Reduce intake air temperature
  • Increase oxygen density
  • Improve combustion efficiency
• Robust Block and Head Design: Heavy-duty cast iron blocks and heads ensure:
  • High thermal stability
  • Long operational lifespan
  • Resistance to high-pressure conditions
• Integrated Control Systems: Cummins’ ECUs monitor:
  • Engine load
  • Temperature
  • Fuel consumption
  • Fault diagnostics

This allows for remote monitoring, integration into building management systems, and predictive maintenance.

Popular Cummins Engine Models Used in Generators

Here are some Cummins engines frequently found in the generators we supply at GFE Power Products:

Engine Model	Typical Power Range	Applications
4BT/6BT Series	20-100kVA	Light commercial, telecoms, construction
QSB Series	100-300 kVA	Industrial, agricultural, remote facilities
