IPC: F02D41/38
Filed: 2000-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent an influence on actuation of an injector due to variation in a state of controlling fuel in a common-rail fuel injection device. SOLUTION: An ECU 81 conducts injection control of an injector 1 by controlling charging/discharging of a piezoactuator 13 press-driving a ball 63 arranged in a valve chamber 55 and switching seating and separating of the ball 63 to switch high and low degree of back pressure of a needle 61. When detected common-rail pressure is low, the pressure of high-pressure fuel inducted for controlling into the valve chamber 55 acting against the action of the piezoactuator 13 at charging is also determined as low, so that the ECU 81 is established to decrease the charging amount of the piezoactuator 13. Therefore, an impact at the time of seating the ball 63 in a seat 551 is lessened to prevent the generation of wear and the like, thereby enabling suitable actuating of the injector 1.

IPC: B01D29/60
Filed: 2000-10-27
Abstract: PROBLEM TO BE SOLVED: To enable the removal of a very small contaminant, which has been could not removed before, and to purify lubricating oil with higher precision.
