QSX15 Series Cummins Diesel Engine


A revolution in diesel power generation.

Delivering unmatched power and efficiency in a compact package, the QSX15 series is the first heavy duty diesel engine to feature 24-valve DOHC technology. It uses 30% fewer parts than comparable diesels and has been engineered to eliminate the need for external lube, coolant and fuel lines to improve reliability at high power outputs.

Ideal for open and enclosed applications in static or portable equipment, it can be matched to meet the specific duty cycle and operating conditions of any generator set.

The Holset HX82 turbo-wastegate design optimizes operation across the torque curve and improves response.

Manifold Design - Integrated fluid circuit replaces hoses and eliminates potential leaks.

High Pressure Fuel Injection - Capable of withstanding pressures in excess of 1,900 bar (28,000 psi) for cleaner, more fuel efficient combustion.

The 24-valve cylinder head has four valves per cylinder for increased power and quicker response per rpm.

Coolpac Integrated Design - Product offers complete cooling packs and air filter kits for complete power packs. Each component is specially developed and rigorously tested for G-Drive products to ensure high performance, durability and reliability.

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.

Emission Standards

To protect public health and protect our planet's natural resources, legislation by the U.S. Environmental Protection Agency (EPA) and European Union (EU) regulators over the past decade has mandated that pollutants - such as nitrogen oxides (NOx), carbon Hydrogen Compounds (HC) and Particulate Matter (PM) - are reduced.

During this time, Cummins has been at the forefront of meeting these new standards, becoming:

First manufacturer to bring EPA Tier-2 and Tier-3 products to market - ahead of regulatory deadlines;

The first manufacturer to introduce an EU Stage IIIA compliant generator-driven diesel engine to Europe;

A leader in innovative emissions solutions, focusing primarily on in-cylinder design improvements to eliminate most NOx, HC and PM before they form.

As a result, our diesel engines are not only very clean, but retain all their performance benefits without resorting to exhaust aftertreatment strategies that add cost and complicate end-user maintenance.

G-Drive engine

Mid-range (1.3 - 9L) mid-horsepower engines (16 to 476 hp) offering the widest Tier 3 range, further reducing 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 1500 and 1800 rpm, designed to meet Tier 2/Stage II emissions requirements for electronics and diagnostics, base engine and turbo, power cylinder and fuel system.
