Generac’s Bi-FuelT engine generators offer a distinct cost advantage over more complex low pressure or high pressure injected natural gas engines, both in terms of initial capital investment and replacement part costs.
The concept of using Bi-FuelT on diesel engines is not new. This approach has found application in large installations that typically operate for extended periods, producing prime or continuous power. Generac now brings the benefits of this technology to the standby generator market.
Combining diesel fuel with natural gas in Bi-FuelT operation provides several benefits compared to engines fueled only by diesel or natural gas. Major benefits include:
- Extended run time capabilities
- Reduced diesel fuel storage requirements
- Lower acquisition cost per kW compared to spark-ignited engines
- Improved reliability with redundant fuel supply
- Reduced maintenance costs
- Lower exhaust emissions than diesel engines
In Generac’s design, natural gas is mixed with intake air just prior to the turbocharger. Since a single, low pressure delivery system is used, additional engine component costs are minimized. Advanced microprocessor, sensor and actuator technologies can now economically provide the precision and response necessary to control the system. Generac selected this approach because it offers the broadest range of operation at the lowest cost, and is best suited for the standby generator market.
Generac’s PowerManager® Digital Control Platform incorporates digital control of Bi-FuelT operation with all other generator control functions into a single, powerful, microprocessor-based module. Benefits include fast system response, minimized interconnect wiring, easy system monitoring and advanced diagnostic capabilities.
