Title: Fuel injection timing control device of diesel engine
Inventor: TOMITA YOSHIAKI
IPC: F02D1/18
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent temporary dropping of fuel injection timing on the lag side against a target value as a timer piston is pushed back as driving reaction suddenly increases at the time of returning from a state where resistance of a high pressure plunger is small by decelerating fuel cut. SOLUTION: A target value of fuel injection timing is set on the lag side rather than idling time, setting to the lag side is released in advance of fuel returning and it is gradually returned to setting at the time of idling at the time of stopping decelerating fuel (a). Alternatively, the target value of the fuel injection timing is temporarily changed to the timing advance side in advance of fuel returning (b). Conventionally, a timer piston is pushed back by sudden increase of driving reaction at the time of fuel returning and actual injection timing drops in the lag side (c), but it is possible to prevent temporary dropping of the fuel injection timing on the lag side by securing timer piston control pressure and inertial force against sudden increase of the driving reaction at the time of returning by control at the time of deceleration and the time of returning.

Then, unit temperature counts added or subtracted when the temperature rises or falls are read out of a unit temperature counting memory section 64B to be stored into a unit temperature counts setting section 64A. Then, a light intensity ratio of a measuring data is inputted from a photodetector 5 and new temperature countings are computed to be sent to a display means 7, a memory means 62 and a temperature counts reference value setting means 66. This operation is repeated to the end of a measurement. This enables measurement of a temperature and directivity of a change in the temperature instantaneously.

Filed: 1993-09-01
Abstract: PURPOSE:To measure the size of a material to be measured (electron beam) without moving it by plurally diving a single laser beam, and providing a means for changing the wavelength of the beam in the route of the divided beam. CONSTITUTION:The laser beam 2 generated from a laser source 1 is divided 3 into beams 52, 53. The beam 52 is passed through a Raman cell 51 provided on the route to form a beam 68. The Raman cell 51 changes the wavelength of the beam 58 so that it is differed from the wavelength of the beam 2. When the beams 53 (having the same wavelength as the beam 2) and 58 are combined together in the common focus 36 of lenses 19, 25, a beat is caused to periodically fluctuate the wavelength, and the interference fringe becomes a progressive wave or regressive wave in the position of the focus 26 according to the direction of the difference of waveform. The fringe space of the interference fringe depends on the wavelength of the beam 2, and the moving speed of the interference fringe is determined depending on the difference of frequency between the beams 53, 58. Since the size of a material to be measured (electron beam 54) is measured by moving the interference fringe, the measurement can be precisely performed.
