Electronic fuel injection
HPFi®
Dresser-Rand
The Dresser-Rand Enginuity HPFi was the first advanced combustion control technology for direct-injected, natural gas-fired industrial engines. 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 at a fraction of the cost of traditional combustion retrofit technology. With HPFi, poor air/fuel mixing and unbalanced fuel metering between cylinders are a thing of the past.
HPFi provides exact control of the fuel gas to provide 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. We have 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.
