Product catalog summary

Dual Fuel Operation Overview
Cummins dual fuel engines mix natural gas with intake air, using diesel as the ignition source. This setup maintains diesel start-up, power density, and transient performance, allowing for a 50-70% substitution rate of diesel with natural gas.

Cost Savings and Energy Efficiency
Utilizing natural gas, which is cheaper and more abundant than diesel, can reduce fuel costs by up to 40%. This promotes energy independence and improves operational cost efficiency. Dual fuel engines can operate on 100% diesel or a mixture of diesel and natural gas, but not on natural gas alone.

Operational Flexibility
The engines offer flexibility to run on 100% diesel in areas with unreliable natural gas supply. Fuel savings depend on the type of natural gas used, such as CNG, LNG, or field gas, with varying substitution rates.

Technical Specifications
The substitution rate is a critical parameter, with Cummins engines achieving up to 70% substitution. The engines maintain the same power density, torque, and transient response as traditional diesel engines.

Emissions and Compliance
In the U.S., dual fuel engines must comply with EPA diesel requirements. Cummins engines meet these standards using a Diesel Oxidation Catalyst (DOC) to reduce CO and non-methane hydrocarbons, compliant with 40GFR09 EPA Tier 2 regulations.

Warranty and Support
Cummins offers a comprehensive warranty, covering unlimited hours in the first year and extending to 2 years or 2,000 hours. Major components are covered for 3 years or 10,000 hours. Engines with a retrofit kit have a 1-year or 1,000-hour warranty.

Service Network
Cummins boasts the largest parts and service network globally, with over 600 authorized distributors. For more information, visit cumminsoilandgas.com or contact a local distributor.

Every Engine. Cleaner. In the United States, dual fuel engines must meet the applicable compression ignition emissions regulations and U.S. Environmental Protection Agency (EPA) diesel requirements. While specifics may vary, an oxidation catalyst is typically required in order to lower carbon monoxide (CO) and non-methane hydrocarbons. The Cummins dual fuel system is compliant with 40GFR09 EPA Tier 2 regulations using a Cummins Diesel Oxidation Catalyst (DOC). The DOC is a drop-in replacement for the equipment’s muffler, and is composed of stainless steel. Every Confidence. Cummins dual fuel...
