摘要： PURPOSE:To avoid the problem that the operation of an EGR valve is delayed and exhaust emission is deteriorated at the time of acceleration or deceleration of a vehicle by controlling the EGR valve provided on an exhaust gas re- circulating path so that its opening is increased as the pressure difference between the front and rear of a throttle valve in a suction path is increased. CONSTITUTION:An EGR path 53 branched from the exhaust path 52 of an engine is opened at the downstream side of a throttle valve 1 arranged in a suction path 51, and an EGR valve 4 is provided in the middle of the EGR path 53. The EGR valve 4 is constituted to open or close a valve body 41 in response to the pressure difference between pressure chambers 43 and 44 above and below a diaphragm 42, and the pressure chambers 43 and 44 are communicated to the downstream position and the upstream position of the throttle valve 1 by pressure guiding paths 54 and 55 respectively. Both pressure guiding paths 54 and 55 are communicated by a bypass path 56 provided with a solenoid switch valve 6 opened only at the time of idling and when the cooling water temperature is the preset value or below. The EGR valve 4 is opened or closed by the pressure difference between the front and rear of the throttle valve 1, thereby the operation of an accelerator pedal 11 can be instantly responded.

摘要： PURPOSE:To further enable a fine electric control to be performed while ensuring the displacement of sufficient driving, by controlling an oil hydraulic circuit by a piezo-actuator. CONSTITUTION:A housing forms in its inside a pressure transforming chamber 38 to be partitioned, and its volume is controlled to be adjusted in accordance with an electric signal by a piezo-actuator 31. While the piezo-actuator 31, converting its displacement into an oil hydraulic control, controls a driven part of intake valve or the like. By this constitution, a fine electric control can be additionally performed while ensuring the displacement of sufficient driving.

摘要： PURPOSE:To contrive to miniaturize and simplify a piezoelectric motor by forming a piezoelectric element into a plate and making a cavity in said plate. CONSTITUTION:To constitute a piezoelectric motor, a rotor 2 supported by an output rotating shaft 3 is provided within a housing 7 and a piezoelectric plate 1 is arranged above said rotor so that its tip 11 touches the top face of the rotor 2. Further, this piezoelectric plate l is inclined at an angle theta and urged on the outer peripheral face of the rotor 2 by means of a biasing plate 4, a bolt 5 and a coiled spring 6 via felt 4. In this case, the piezoelectric plate 1 is made gradually smaller in the width of its tip and a circular cavity 13 is provided in the plate. Moreover, a conducting electrode is formed all over both faces of the piezoelectric plate l so that an AC power is appled thereto. Thus, a guantity of expansion deformation of said plate 1 becomes large by provision of the cavity 13 so as to increase the rotational speed and torque of motor output substantially.

摘要： PURPOSE:To perform an exact initiation and completion of a fuel injection and an accurate control of a fuel injection rate by opening or closing a fluid passage through the movement of a valve body caused by charging an electric charge in capacitor means or discharging from the capacitor means to an electrostrictive element. CONSTITUTION:Drive means 25' shrink an electrostrictive element 14 by discharging an electric charge produced in the electrostrictive element 14 by means of first switching means 250 at a given time, moving a valve body 19 to an opening position. Also, the drive means 25' move an electric charge produced in the electrostrictive element 14 through second switching means 246 and 247 at another given time, shrinking the electrostrictive element 14 to move the valve body to the opening position. Further, the electric charge stored in capacitor means 248 and supplied to the electrostrictive element 14 at a given time stretches the element 14 to move the valve body to a closing position. Thus, an exact initiation and completion of a fuel injection and an accurate control of a fuel injection rate are enabled.

摘要： PROBLEM TO BE SOLVED: To perform ignition at plural places in each cylinder while avoiding the cost increase and larger size of an igniting power supply. SOLUTION: A pair of diodes 108, 109 electrically connected to each other in the opposite directions are provided between a spark plug 1 having a pair of discharge gaps G1, G2 and an igniting power supply 2 for applying high voltage to the spark plug 1 with the generation of AC voltage. When the voltage of the igniting power supply 2 is positive, high voltage is applied to one discharge gap, and when the voltage of the igniting power supply 2 is negative, high voltage is applied to the other discharge gap. High voltage can be applied to the pair of discharge gaps G1, G2 using one igniting power supply 2, and so conventional igniting power supplies can be reduced to half. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To improve an ion current detection accuracy and accordingly accurately determine the state of combustion. SOLUTION: In an ignition coil 21, a transistor 23 is connected to a primary winding 21a and a current detecting resistance 26 is connected to a secondary winding 21b. A current flowing across the counter electrodes 11 and 12 of an ignition plug 10 is detected by the current detecting resistance 26. When ignition is made by the ignition plug 10, a high speed rectangular wave signal (repetition signal) by an oscillator 25 is outputted after an ignition signal IGT is cut out, and the transistor 23 is turned ON/OFF by the rectangular wave signal. By this, a battery voltage is intermittently applied to the primary winding 21a of the ignition coil 21, and an ion current is measured by the application of the voltage. In this case, the frequency of the rectangular wave signal caused by the oscillator 25 is set so as to match the resonance frequency f0 of the ion current route comprising the ignition plug 10, the secondary winding 21b of the ignition coil 21, and the current detecting resistance 26.
