Abstract: PURPOSE:To suppress the request voltage with wider gap and enhance the durability by furnishing No. 3 electrode outside a central electrode and a grounding electrode, forming an aux. gap between the central electrode and No. 3 electrode for generation of capacitance discharge at a low voltage, and by inducing discharge of a normal gap with capacitance discharge of the aux. gap. CONSTITUTION:A conductor is coated over the periphery of the tip of an insulator 3 around a central electrode 1, to form No. 3 electrode 4. An aux. gap S2 is formed between this No. 3 electrode 4 and central electrode 1. When a high voltage is impressed to the central electrode 1, a weak No. 1 capacitance discharge is generated in the aux. gap S2. As the No. 3 electrode 4 is grounded through capacitance component (capacitor), dicharge to the No. 3 electrode 4 is made only in the amount corresponding to the capacitance of the capacitor, wherein no transfer is made to induction discharge. When discharge is generated at the aux. gap S2, many ions and free electrons are produced. Triggered by them, No. 2 capacitance discharge is generated at the normal gap S1, and transfer is made to induction discharge.

Abstract: PROBLEM TO BE SOLVED: To suppress overheat of an engine by energizing a valve to the opened condition. SOLUTION: This temperature regulating device is provided with a valve 1000 changing distribution of velocity of exhaust gas flowing in an exhaust port in the exhaust port. When the valve 1000 is closed, heat transmission from exhaust gas to a cylinder head is increased and temperature rise of the engine is promoted. When the valve 1000 is opened, promotion of engine temperature rise is stopped. An arm part 1010 extending vertically from a valve stem 1002 of the valve 1000 is connected to the cylinder head 104 via a spring 1020. The spring 1020 energizes the arm part 1010 to close the valve 1000. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To increase quantity of heat transmitted to cooling water by providing a first flow passage and a second flow passage.
SOLUTION: A cooling water passage 400 includes the first flow passage 402 in which cooling water circulating in a cylinder block 102 and a cylinder head 104 flows out and the second flow passage 404 in which cooling water circulating in the cylinder block 102 flows out. A valve 500 is provided in the second flow passage 404. While an engine 100 is heated, the valve 500 is controlled into an opened condition. Consequently, cooling water circulating in the cylinder block 102 flows out into the second flow passage 404. In this case, cooling water circulates in the cylinder block 102 and flows out into the second flow passage 404 without circulating in the cylinder head 104.

Abstract: PROBLEM TO BE SOLVED: To provide a temperature regulating device for an internal combustion engine capable of controlling heat quantity recovered from exhaust gas in a wide range.
SOLUTION: The temperature regulating device for the engine is formed at a position surrounded by an inner wall 22, and is provided with an exhaust port 31 in which exhaust gas flows, a valve 51 provided in an exhaust port 31, and an actuator connected to the valve 51 and controlling open and close of the valve 51. When the valve 51 is controlled to a close side, flow speed of exhaust gas flowing along an inner wall 22 gets low as compared with a condition where the valve 51 opens and flow speed of exhaust gas flowing at a position separate from the inner wall 22 gets large. The valve 51 includes a ring shape extending along the inner wall 22 under a close condition.
