摘要： To provide a compressor housing for a turbocharger, which makes it possible to prevent reduction of compression efficiency and to maintain holdability for an abradable seal, and which is advantageous in terms of cost, and a method of manufacturing the same. A compressor housing (1) for a turbocharger includes a housing body (20) to house an impeller (10), an annular abradable seal (30) to form a shroud surface (31). The abradable seal (30) includes a flange (32) that projects outwardly in a radial direction of the abradable seal, and is disposed in an inner circumferential recess (21) that is formed on an inner circumference surface of the housing body (20). In addition, the abradable seal is fixed by having the flange (32) held between a press-fitting direction forward surface (41) of a ring member (40) and a recess opposing surface (213) of the inner circumferential recess (21), which opposes the press-fitting direction forward surface (41), by press-fitting the ring member (40) into the inner circumferential recess (21).

摘要： A variable valve mechanism of an internal combustion engine includes a cam, a transmission mechanism, a first variable device that controls the transmission mechanism to continuously change at least a maximum lift amount of a lift curve indicating a lift amount of a valve that corresponds to a rotation angle of the internal combustion engine, and a second variable device that controls the transmission mechanism to continuously change at least an operation angle of the lift curve. When the lift curve lies in any condition within a predetermined range that covers all or part of a variable range of the lift curve, an absolute value of a ratio of a maximum lift amount variation to an operation angle variation for a slight change from the condition caused by the first variable device is larger than that for a slight change from the condition caused by the second variable device.

摘要： A variable valve mechanism of an internal combustion engine includes a camshaft having a general shaft part and a cam part arranged next to each other in an axial direction, an input arm that swings when pressed by the cam part, an output arm that is swingably mounted and that drives a valve when swinging, and a switch device that switches the variable valve mechanism between a coupled state where the input arm and the output arm are coupled to swing together and an uncoupled state. The output arm has a great height so that clearance between the output arm and the general shaft part is 3 mm or less when the variable valve mechanism is in the coupled state and the valve is closed. If the output arm bounces in the uncoupled state, the output arm comes into contact with the general shaft part through the clearance.
