Diesel Dual Fuel is a technology in which natural gas is precisely metered into the air intake of a diesel engine, creating an increase in horse power while not harming the engine. The increased horse power allows the engine to run on lower amounts of diesel fuel due to the natural gas allowing the driver to use less throttle while maintaining the same performance. Dual fuel applications have been used for decades, but the conversion equipment has improved as the infrastructure and availability of CNG grows across the country. For many fleets, utilizing the dual fuel approach proves a bridge to transitioning equipment to dedicated natural gas engines.
Stirk CNG Diesel Dual Fuel Research Originally, Stirk's dual-fuel experience came from relationships with farmers who were metering natural gas into their diesel irrigation engines. These systems allowed irrigation power units to displace up to 80% of the diesel usage due to the application being a stationary engine under constant pull. The nature of over-the-road diesel engines is more complex. Dual-fuel systems for trucks must read the parameters of the engine and the driver to precisely meter the correct amount of natural gas into the engine.
Dual Fuel Solutions and Real-Time Fuel Data Not all systems and applications can deliver the fuel displacements necessary to justify the capital cost of conversions. This is where the experience and expertise of Stirk CNG can help. We have hands on experience and have developed resources to determine if dual-fuel is right for your operation. Clients of Stirk have access to on-going research data and training on dual-fuel. Registered users can also access real-time fuel data on all of Stirk's research trucks and fleet partner vehicles. This allows fleets to avoid going it alone, and provides a network of resources to convert to CNG.
