HPFi® is an electronically controlled, high-pressure fuel injection system that combines several proven control components aimed at meeting very stringent operating, performance, and emissions requirements. This technology eliminates many of the characteristic problems of direct-injected, large-bore, natural gas-fired engines.

HPFi  provides exact control of the fuel gas injection event. Add to this control precision the mixing energy of a high-pressure jet of fuel gas, and you get an optimally mixed air/fuel charge that produces combustion performance and emissions characteristics equivalent to well-designed, state-of-the-art IC engines.

The commercial availability of HPFi  is the result of our commitment to turn advanced technology into applied solutions. Enginuity Products has worked with key suppliers, including Woodward Industrial Controls, to develop a well-engineered system that provides a cost-effective strategy for upgrading existing engines in the field.

HPFi  is another example of technology that works.

Additional Benefits of HPFi  include:

• Up to 80% reduction of NOx emissions*
• Up to 50% reduction of CO emissions*
• Up to 8% fuel savings*
• Improved start-up reliability
• Easy integration with iMPACT for closed-loop balancing and combustion control
• Elimination of mechanical governor and valve train

*According to actual test data.  Specific results will vary depending on engine make and model and operation conditions.

Performance and Operating Characteristics:

• Direct electronically controlled fuel injection
• High fuel injection pressure
• Superior in-cylinder air/fuel mixing
• Precise fuel injection metering
• User-defined emissions and fuel performance
• Simple open-loop to sophisticated closed-loop control of individual injectors
• Adaptive speed/load optimization
