Sensing and control methods and apparatus for common rail injectors

摘要: A fuel injector employs at least one sensing device for changes in the thermodynamic properties of within to thereby monitor performance during usage. In some embodiments, advantageously placed temperature sensors are employed detect release thermal energy which occurs when potential a high-pressure is suddenly converted into kinetic by lowering pressure fuel. Other embodiments instant invention employ sudden occur course injection cycle. Whereas devices can be variety locations, they preferably flowing an where such appreciably large Preferably, injectors compatible with microprocessor-based fuel-injection control systems maintain near-ideal performance.
