中文摘要:共轨柴油机电控喷油器电磁阀的驱动电路一般采用Peak & Hold驱动方式,在不同的阶段对电流变化的快慢要求不同。为满足喷油过程中对电流的变化要求,从理论上分析电路的状态响应特性,优化电磁阀驱动电路,以提高电磁阀的响应速度,设计了基于自举电路的喷油器驱动电路。试验结果表明,在相同的驱动参数下,优化后的驱动电路在喷油过程中保持阶段电流的波动幅值减小50%,而喷油器关闭过程的响应时间只需20μs,实现了精确控制喷油量和喷油定时的目的。

Abstract:The driving mode of Peak & Hold current shape is adopted in common rail diesel electronic control injector driving circuit. The requirements of current change are different in different stages. In order to meet the changes in the injection process, the state responses characteristics of the circuits to optimize the circuit and improve the response speed of electronic valve were analyzed theoretically. The driving circuit was designed based on the bootstrap circuit. The results showed that the fluctuations amplitude of the current in the hold stage reduced by 50% under the same driving parameters in the optimized circuit, and the response time was only 20μs in the injector closing process, which realized the purpose of precise control of the injection quantity and injection timing.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
