摘要： PURPOSE:To uniformalize combustion in a main combustion chamber, so as to enhance combustion efficiency by approximately equalizing the content volume of both valve recess parts including the content volume of chamber parts to each other through a process of providing a chamfer part connected to at least one periphery of an intake valve recess part and an exhaust valve recess part on the lower surface of a cylinder head. CONSTITUTION:Main combustion chambers 7-1, 7-2 into which jet flow is injected from a nozzle hole 6 opening toward the center of a piston from a sub chamber 5 is symmetrically formed, and an intake valve recess part 2 and an exhaust valve recess part 2 whose shapes are different from each other are formed on the lower surface of a cylinder head, so as to be overlapped on both main combustion chambers 7-1, 7-2. In this case, chamfer parts 2', 4' are formed on at least one peripheries of respective valve recess parts 2, 4, and the content volume of both valve recess parts 2, 4 including the content volume of the chamfer parts 2', 4' are approximately equalized to each other. Thereby, air existing in the main combustion chamber is approximately symmetrically distributed, so as to secure uniform combustion.

摘要： PURPOSE:To provide a valve gear capable of adjusting the operating timing of an auxiliary cam piece. CONSTITUTION:A window hole 112 is opened in an exhaust cam 11 around the outer periphery of it, and an auxiliary cam piece 113 is provided swingably in it. Also an inner shaft with a phase adjusting cam 122 is provided in the hollow part of a hollow camshaft 12, and the rotating angle of the phase adjusting cam is adjusted by an actuator, and thus the valve opening timing and valve opening amount of an exhaust valve can be controlled by the auxiliary cam piece. For example, while an internal combustion engine is operated under partial load, the properties of exhaust gas can be improved by opening the exhaust valve in intake stroke by the auxiliary cam piece to add internal EGR. When the engine is under full load operation, opening of the exhaust valve by the auxiliary cam piece can be stopped to suppress the output of the internal combustion engine from lowering.

摘要： PURPOSE:To prevent the overcharge of a battery when an electric load is disconnected from the alternator. CONSTITUTION:A charger 1 has an alternator 4 and a regulator 5. The rectifier 8 of the alternator 4 is connected to a battery 2 and connected to a catalyst 3 with an electric heater through a catalyst switch 9. An ECU 40 is connected to the catalyst switch 9 and the control transistor 35 of the regulator 5. The instant the catalyst switch 9 is opened, the control transistor 35 is cut off, resulting in zero field current. Therefore, when the catalyst 3 is disconnected from the alternator 4, the control transistor 35 is cut off to turn off an output transistor 19. Therefore, the field current and the alternator current become '0' and the battery 2 is not charged by the alternator 4.

摘要： PURPOSE:To improve a heat exchanging efficiency and simplify and make a light weight heat exchanger with a simple structure. CONSTITUTION:A mid-way part of a corrugated tube having a plurality of expansion portions 2 for use in communicating fluid and set along a longitudinal direction therein is bent at a plurality of bent portions 5 so as to form a plurality of tube rows 4 parallel to each other. Each of upper and lower tube rows 4 adjacent to each other is disposed alternatively in a forward or a rearward direction in respect to a wind receiving direction. A thermal radiation area of the corrugated tube 3 itself is expanded with a plurality of expansion portions 2, a disturbed flow of air is generated by the forward or rearward arrangement of each of the tube rows 4, resulting in that a pressure loss of air is reduced and a thermal radiation amount is increased. In addition, since the corrugated tube 3 having some expansion portions 2 is merely bent, its structure is simple.

摘要： PURPOSE:To shorten the total length to a supercharger in comparison with a device which comprises a large gear and a rotor shaft bearing arranged in parallel to each other by providing such a constitution that the large gear for increasing speed is fittedly supported rotatably on the outer circumference of the bearing of a rotor shaft acting as a driven shaft during increasing speed. CONSTITUTION:In order to rotate a rotor shaft 3a, a multiplate type crack 12 is connected to a large gear 14 which has a larger diameter than that of a small gear 7, has more gear teeth than it, and meshes with the small gear 7. In addition, in order to support the large gear 14, the bearing part 6b of a housing 6 for supporting a rotor shaft 3b is formed cylindrically, and a ball bearing 15 is fitted thereon, while the large gear 14 is fittedly supported on the outside of the ball bearing 15, rotatably in relation to the housing 6. Further, the large gear 14 acting as a speed increasing device is engaged with the bearing 6b so that the bearing 6 forms the shaft of the large gear 14, instead of being arranged in parallel to the bearing 6b of the rotor shaft 3b. Therefore, the total length of a supercharger is thus shortened by a partial length of the large gear 14 fitted in the bearing 6b.

摘要： PROBLEM TO BE SOLVED: To materialize efficient energy recovery by regeneration while maintaining the deceleration feeling that a driver requests. SOLUTION: The objective quantity of regeneration is computed (step S12), being tinged with car speed and accelerator opening, so that the quantity of regeneration by a motor generator may increase more the lower the stage is, based on the shift stage of a multimode manual transmission (MMT) at request for deceleration and besides at fuel cut(step S10-YES and Step 11-YES), and the regeneration control of the motor generator is executed so that it may be the objective quantity of regeneration in question, whereby pseudo engine brake feeling is generated (step S13). In this case, the actual speed change stage of the above MMT is not shifted. On the other hand, in case that fuel is not cut (step S11)at deceleration(step11-NO), the regeneration control of the motor generator is inhibited (step S14). COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of a stabilizing engine combustion state even if characteristics of a gas in an engine combustion chamber excessively vary.
SOLUTION: In an electronic control unit 32 for a centralized control of an operating condition of an engine 1, the temperature T1 of the gas in a combustion chamber 2 at a prescribed time CA1 prior to fuel injection timing is calculated as a function of a cylinder internal pressure PS1, volume V1 and weight G1 at the time CA1. On the basis of the temperature T1 at the prescribed time CA1, the optimum fuel injection timing for stabilizing the combustion state of the engine 1 is determined. As a result, the characteristics of the gas filled in the combustion chamber 2 is immediately grasped. The characteristics can be reflected to the fuel injection timing adopted immediately thereafter (for example, in the same combustion cycle).
