摘要： A throttle valve control device for an internal combustion engine characterized in that a throttle valve is rotatably mounted on a throttle body via throttle shaft, that the configuration of a bore in the inner surface of the throttle body is a straight bore type in which the centre of rotation of the throttle valve is located on the centre line of the throttle body, that a spherically surfaced internal profile portion is provided in an idle control area which is in the vicinity of the fully closed angle of the throttle valve, that a spherically surfaced internal profile portion is further provided as an area continuing from the sphrically surfaced internal profile, that provided as an area continuing from the spherically surfaced internal profile is an area comprising a compound surface profile comprising in turn a spherical surface and a cylindrical surface substantially parallel to a flow of air or an area comprising a conical surface profile, and that the centre of the spherically surfaced profiles is on the centre line of the bore and vertically offset, whereby a gap between the spherical surface profile and the throttle valve increases as the opening of the throttle valve increases. When applied to an electronically controlled throttle valve control device, the device is designed such that an engine rotational speed changes 20 rpm for each incremental throttle valve opening of 0.10 in a low throttle valve opening area, thereby eliminating an idle control by an ISC valve.

摘要： PROBLEM TO BE SOLVED: To ensure a resin intake manifold in an engine, which can ensure a sufficient strength without increasing the side of its structure. SOLUTION: A branch part 3 is firmly fastened to a cylindrical pipe 6 by using a fastening bolt 11 so as to prevent a curved part of the branch part 3 from being deformed. A spacer 15 having a stiffness which is higher than that of rubber or the like is interposed between the branch part 3 and the cylindrical pipe 6, and the outer periphery of the spacer 15 is sealed by means of a connecting member 19 made of rubber, and a fastener 10 for fastening the outside of the connecting member 9. Even though the branch part 3 is firmly fastened to the cylinder pipe 6 by the fastening bolt 11, an exhaust passage can be ensured by a clearance defined by the spacer 15, and by adjusting the fastening force of the fastener 10 so as to swell the connection part 9, air leaks below the pressure resistance strength of an intake manifold, thereby it is possible to prevent breakage of the intake manifold.
