摘要： PURPOSE:To effect the altitude compensation of the EGR device with a low cost by utilizing a fact that the absolute pressure of the vacuum source of a vacuum pump is made smaller as compared to the variation of atmospheric pressure. CONSTITUTION:A pressure actuator 2 is integrated with an EGR valve 3 while a pressure chamber 20 is constituted by a case 23 and a diaphragm chamber 21. The pressure port 26 of the case 23 is communicated with the suction port 11 of the vacuum pump 1. The EGR valve 3 shuts up an EGR path 8 by the energizing force of springs 22, 23 when the pressures of the pressure chamber 20 and a vacuum chamber 30 are same as the atmospheric pressure and, further, shuts the path 8 when the vacuum of the vacuum chamber 30 is smaller than a value corresponding to the energizing force of the spring 32 even if the pressure of the pressure chamber 20 becomes the same as the suction pressure of the vacuum pump. In case the suction pressure of the vacuum pump is utilized, little leakage from sealing positions may be allowed, therefore, the diaphragm type pressure actuator may be obtained by an inexpensive material such as rubber or the like.

摘要： PURPOSE:To provide constantly a suitable swirl according to the operation condition by detecting the variation rate of torque and controlling a swirl control valve on the basis of the detection. CONSTITUTION:Torque is detected by a pressure detector 920 to check a trifle torque variation rate DELTATe with respect to a trifle variation rate DELTAtheta of the opening angle theta of a swirl control valve 4. If DELTATe is larger than (vr)1 (a value specified in accordance with the operating condition), a current through the solenoid coil 75 of a control valve 7 is increased to pull down a plunger 76 to intensify the negative pressure from a vacuum pump 8, then the opening angle of the swirl control valve 4 is reduced so that the swirl may be weakened. If DELTATe is equal to or a little smaller than vr1, the angle theta will not vary and if DELTATe is clearly smaller than vr1, the angle is varied by DELTAtheta in the reverse direction.

摘要： PURPOSE:To correctly control the ignition timing by invariably circulating the cooling water or engine oil around a heat sensitive member and making the heat sensitive member not liable to be affected by the outside temperature so that it is displaced in response to the temperature rise of the cooling water or engine oil and rotates a rotary plate. CONSTITUTION:If the water (oil) temperature is constant, the pushing force of a heat sensitive member 49 and the reaction force of a spring 46 are balanced, and a piston 44 stays at a fixed position. Thereby the ignition timing is controlled only by a vacuum controller 2 operated by the negative pressure of a suction pipe. However, when the cooling water temperature is increased or decreased, the piston is moved to a position where the pushing force of the heat sensitive member 49 and the reaction force of the spring 46 are balanced, and a rotary plate 7 is rotated to correct the ignition timing. This action is performed only by an oil/water temperature control unit 4 without changing the stroke of the vacuum controller 2. Accordingly, the correction is feasible even under a full load, and the correct ignition timing is controlled.
摘要翻译：目的：通过使冷却水或发动机油不断使热敏元件周围循环来正确地控制点火正时，并使热敏元件不会受到外界温度的影响，从而响应于温度升高冷却水或发动机油旋转旋转盘。构成：如果水（油）温度恒定，则热敏构件49的推压力和弹簧46的反作用力平衡，活塞44停留在固定位置。因此，点火正时仅由通过吸管的负压操作的真空控制器2控制。然而，当冷却水温度升高或降低时，活塞移动到热敏元件49的推力和弹簧46的反作用力平衡的位置，旋转板7旋转以校正点火正时该操作仅由油/水温度控制单元4执行，而不改变真空控制器2的行程。因此，即使在满载下也可以进行校正，并且控制正确的点火正时。

摘要： PURPOSE:To obtain the optimum EGR all the time regardless of variation in atmospheric pressure by providing a glow-plug 1 with both a pressure-receiving cylinder, which is displaced in response to the pressure in a combustion chamber, and a piezoelectric element, which transforms the said displacement into an electric signal, and by regulating the opening of an EGR valve in response to the output from the element. CONSTITUTION:A glow plug 1, which is installed on a cylinder head through a plug body 14 whose outer surface is provided with threads 14a, is formed by placing a pressure receiving cylinder 12, the tip of which is provided with a heater that is electrified via an electrode rod 13, so that the cylinder 12 can move in the direction of the axis. This pressure receiving cylinder 12 is pushed upward by the pressure in a combustion chamber. In response to this displacement, a pair of piezoelectric elements, 1a and 1b, are compressed so that an electric signal is output from a signal line 10. This electric signal enters operation circuit 7, where the operation to obtain a desirable amount of EGR corresponding to engine conditions is carried out in order to regulate the circuit- closing time to a solenoid 61 of a negative pressure control valve 6. With this contrivance, the rate of negative flow passing the negative pressure control valve 6 can be controlled, thereby regulating the opening of an EGR valve 3.
