摘要： PROBLEM TO BE SOLVED: To reduce the amount of exhaust gas passed through nozzle side clearances. SOLUTION: The variable displacement supercharger 10 includes nozzle plates 13a, 13b forming an annular exhaust flow passage 17 in the periphery of a turbine wheel 12 and a plurality of nozzle vanes 14 rotatably journaled to the nozzle plates. The wall surfaces of the nozzle plates are provided with grooves 131, 132 formed in an upstream side of exhaust gas led to flow from the nozzle vanes into the exhaust flow passage. Thereby, the direction of the exhaust gas flowing in the vicinity of the wall surfaces of the nozzle plates is changed to a direction separated from the wall surfaces and approaching the centers of the nozzle vanes by vortex flows 31, 32 formed when the exhaust gas is passed through the grooves. The amount with the exhaust gas flowing in the vicinity of the wall surfaces of the nozzle plates passed through the nozzle side clearances 21, 22 is reduced, the amount of the exhaust gas with speed increased by the nozzle vanes is increased, and supercharging efficiency is improved. Since the amount of the clearance is not reduced, the sliding resistance of the nozzle vanes is not increased. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a supercharger system of an internal combustion engine, which both reduces heat capacity of a turbine housing and improves turbo efficiency, at the same time. SOLUTION: The heat capacity of the turbine housing 2 is reduced by adopting an aluminum alloy as a constituting material of the turbine housing 2. The turbine housing 2 is cooled by engine cooling water so that the ratio of the temperature of the turbine housing 2 and the temperature of a turbine wheel 51, becomes the relationship of the reciprocal ratio, to the ratio of an expansion coefficient of the constituting material of the turbine housing 2 and an expansion coefficient of a constituting material of the turbine wheel 51. Thus, both early activation of a catalyst by reduction in the heat capacity of the turbine housing 2 and continuous security of high turbo efficiency by maintenance of a tip clearance, are made compatible.

摘要： PROBLEM TO BE SOLVED: To provide a crank angle phase variable device capable of surely holding a crank pin in the predetermined angle phase. SOLUTION: A crank arm 23 of a crank shaft 14 is supported on a crank spindle 16 freely to relatively rotate, and the crank pin 31 is integrally provided with the crank arm 23 at a position displaced from the center of rotation of the crank spindle 16. This crank angle phase variable device engages a lock pin 57 inside the crank arm 23 with a lock hole 55 of the crank spindle 16 to connect (lock) the crank arm 23 to (with) the crank spindle 16, preventing relative rotation thereof. Crank angle phase of the crank pin 31 can be changed by evacuating the lock pin 57 out of the lock hole 55 and relatively rotating the crank arms 22 and 23 in relation to the crank spindle 16 with the cylinder-inside pressure applied to the crank pin 31 through a piston.

摘要： PROBLEM TO BE SOLVED: To provide a movement direction conversion structure for an internal combustion engine, capable of effectively taking out combustion pressure as torque of an output shaft while preventing a top dead-center of a piston from occurring twice and preventing an engine rotating speed effectively operating from being restricted. SOLUTION: The output shaft 15 is installed at a place away from a center line CL of a cylinder 12 and reciprocating linear motion of the piston 13 is converted into rotational motion of the output shaft 15 by the movement direction conversion structure 17. A second link 25 of the structure 17 is connected to the output shaft 15 and a first link 22 so as to transmit a power and is shaken downward while using the output shaft 15 as a fulcrum as the piston 13 is lowered with the combustion pressure. The second link 25 is shaken upward while using the output shaft 15 as the fulcrum and the piston 13 is lifted by rotating a crank member 18. A slide plate 27 and a one-way clutch 28 are installed between the second link 25 and the output shaft 15 so that only one-way shaking of shaking in a vertical direction of the second link 25 is transmitted to the output shaft 15.
