Within-A-Cycle Control of Rate Shaping with Piezoelectric Fuel Injectors


Summary

Researchers at Purdue University have developed a model-based, closed-loop controller of injection flow rate for a piezoelectric fuel injectors. This within-a-cycle control strategy utilizes a model-based, generalizable scheme and shows an injection flow rate tracking capability. The performance of this controller has been verified with simulation and experimental results at different rail pressures and desired injection rates, which indicate a maximum error of total fuel per one injection event of 2.5 percent.
