摘要:
Using a control coil (11) having a high response characteristic suited to the valve opening and a hold coil (12) suited to hold a large force by a small current, during the valve opening time a high voltage is applied to the control coil suited to the valve opening and during a valve opening hold time a low and stabilized voltage is applied to the hold coil suite to the holding, and then a valve body driven. In a fuel injection apparatus, a drive manner during a valve opening time and a hold time is optimized.
摘要(中):
使用具有适合于阀开口的高响应特性的控制线圈(11)和适合于通过小电流保持大的力的保持线圈(12),在开阀时间期间,对控制线圈施加适当的高电压 到阀开度,在阀打开保持时间期间,将低稳定的电压施加到保持线圈套件到保持件,然后阀体驱动。 在燃料喷射装置中,优选在开阀时间和保持时间期间的驱动方式。
