Dual-Fuel Control Strategy Using ARi Engine Test Labs
Project Scope
A heavy machinery OEM approached ARi to develop and validate control strategies on large duel fuel engines. They chose ARi for our highly skilled manpower in both fabrication and testing domains, unmatched facility uptime, reliable measurement and data acquisition systems, state of the art fuel blending techniques, and storage systems.
Business Challenges
- The engine had to start on diesel and then change over to Natural/alternate gas fuel.
- Calibrate the engine control system while experimenting with alternative fuels.
- Utilize Diesel, Natural gas, Propane, Butane, and CO2/Methane Blends.
- Conduct detonation margin analysis and throttle control calibration.
ARi’s Solutions
- Extensive instrumentation used on the engine to capture meaningful results to guide towards the optimal calibration.
- 110 Temperature locations, 85 Pressure locations, 6 Flow measurements, 10Hz data recording.
- 11-month performance program with 94% cell uptime.
- Calibration results with several fuel blends while meeting performance and emissions targets.
- Detailed in-cylinder combustion analysis with pressure vs crank angle traces & oil degradation analysis.
