Diesel B-Series

Power Range
50-176 kVA 50 Hz / 36-110 kWe 60 Hz
3.3/3.9/5.9 litre 4/4/6 cylinder
Small engines - big possibilities.

Small, light and economical, our B-Series engines include a direct fuel injection for a cleaner, quieter, more fuel-efficient performance and offer outstanding value in terms of installation, simplicity and servicing, with valve clearance checks not required until 2,000 hours – twice the industry standard.

All the engines in this series perform well under severe duty cycles and offer excellent fuel consumption, substantial cooling capability, low noise, low weight, and high power output per litre, for first class reliability.


Coolpac Integrated Design - Supplied with cooling package and air cleaner kit for a complete power package.

Single Poly Vee belt drive for fan, alternator and water pump, with self-tensioning idler for minimum maintenance.

Stanadyne DB4 injection pump features advance mechanism for reliable cold starting.

Spin-on fuel filter and full-flow lubricating oil filter.

Top mounted Holset HX30 turbocharger for increased power, fuel economy and lower smoke and noise levels.

Service and Support - G-Drive products are backed by an uncompromising level of technical support and after sales service, delivered through a world class service network..


To protect public health and conserve our planet's natural resources, legislation from the U.S. Environmental Protection Agency (EPA) and regulatory agencies in the European Union (EU) has, for the past decade, required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.

Throughout this time, Cummins Inc. has been at the forefront of the move to meet these new standards, becoming:

  • the first manufacturer to introduce EPA Tier-2 and Tier-3 products to the market - ahead of the regulatory deadline;
  • the first manufacturer to introduce EU Stage IIIA compliant generator-drive diesel engines to Europe;
  • the leader in innovative emissions solutions that focus predominantly on in-cylinder design improvements to eliminate most of the NOx, HC and PM before they are formed.

As a result, our diesel engines are not only very clean, but also retain all of their performance advantages without exhaust after treatment strategies that add cost and complicate maintenance for end users.

G-Drive Engines

  • Mid-range (1.3 - 9L) medium-horsepower engines (16 to 476 hp), providing the broadest Tier 3 range which further reduce Tier 2 NOx levels by 38%
  • Heavy duty (11 - 15L) 415 to 755 hp engines powering commercial operations
  • High-horsepower (19 - 78L) 675 to 3700 hp at both 1500 and 1800 rpm, designed to meet Tier 2/Stage II emissions requirements for electronics and diagnostics, base engine and turbocharging, power cylinder and fuel systems
