Especially, the tire press is improved in the aspects of its machine accuracy, strength, size, and maintenance. The tire press has: a pair of upper and lower molds; a base for supporting the lower mold; side frames on both sides of the base; a side slot vertically extended in each of the side frames; a top slide which slides along the side slots and holds the upper mold; and a crank mechanism for moving the top slide only in the vertical direction. The crank mechanism includes: a crank gear; a lever attached to the crank gear and whose front and is positioned on the outer side of the outer diameter of the crank gear; and a link connecting a crank fulcrum at the tip of the lever and the top slide sliding along the side slots. The side slot vertically extends parallel to a vertical central line crossing the center of rotation of the crank gear and the crank fulcrum. Projected in the central portion through the pair of upper and lower molds are adjusted to an optional height.

摘要： A center mechanism for a tire vulcanizer having a first cylinder whose stroke can be detected with a simplified structure achieves reduction in cost and improvement in working efficiency upon maintenance. The center mechanism expands, while the first cylinder 1 moves downwardly, a bladder 5 into close contact with an inner face of a green tire. A downward stop position of the first cylinder 1 is set in advance by a linear sensor 14. The stroke amount of the first cylinder 1 is detected by a stroke bracket 12 having a stroke portion 12a extending downwardly in parallel to the first cylinder 1 from within a stem 8 and provided so as to advance into the stem 8 together with a cylinder rod 1a, and a linear sensor 14 for detecting the stroke amount of the first cylinder 1 from the stroke portion 12a of the stroke bracket 12 remaining outside the stem 8.

摘要： The present invention has an object to effectively prevent deterioration of combustion characteristics when engine temperature is low. There is provided an intake pressure controller 24 that effects control such that, when an operating condition discriminator 21 that identifies engine temperature identifies low engine temperature after engine start-up, control by an engine controller (feedback controller 23) that performs engine control on fluctuation of intake negative pressure to decrease the intake negative pressure is suppressed until the temperature of the intake passage rises to at or above a predetermined value, and such that the intake negative pressure is made larger.

摘要： An air-fuel ratio control system, has an air-fuel ratio feedback control for feedback controlling an-air-fuel ratio of a mixture to be supplied into an engine based on a parameter detected from an exhaust gas discharged from the engine so as to set said air-fuel ratio to a target air-fuel ratio in an internal combustion engine. Vaporized fuel is supplied from a fuel tank to the engine. During an initial interval, the supply of vaporized fuel gradually increases. Learning an updating of a control value are accomplished in the feedback control based on a deviation of the air-fuel ratio from the target air-fuel ratio during supply of the vaporized fuel. Upon a resumption of supply of vaporized fuel, a learned value setting arrangement gradually changes the learned control value from zero (0) to a learned control value obtained during a preceding period of supply of vaporized fuel according to a gradually increasing amount of supply of vaporized fuel over a given interval.

摘要： A cold-state emission-reducing strategy wherein a diagnostic apparatus examines for possible malfunctions of a control unit during cold start. The diagnosis judges that the strategy is faulty if the cumulative amount of fuel injection is equal to or smaller than a predeterminable threshold value for a faulty judgement. Thus, the abnormality of the cold-state emission-reducing strategy is accurately and easily detected, by merely calculating the cumulative amount of an injection pulse width for the injector or the cumulative amount of fuel flow during a predeterminable cumulating time period after engine start, and comparing the calculated cumulative amount with the predeterminable judgement threshold.

摘要： In a center mechanism of a tire press, which the tire size is changed, the lower limit position of an upper clamp ring is changed to a shaping height corresponding to the size of the exchanged tire only by changing a setting of a controller. Consequently, the work related to the tire size change is facilitated. A bladder is inflated and tightly comes into contact with the inner face of a green tire while lowering the upper periphery of the bladder to the shaping height corresponding to the tire size. The center mechanism includes: an upper clamp mechanism such as an upper clamp ring, that holds the upper periphery of the bladder; a first cylinder for vertically moving the upper clamp mechanism by the reciprocating movement of a piston; a linear sensor for sensing the travel amount of the piston of the first cylinder; and a controller for setting the shaping height as the lower limit position of the upper clamp mechanism and for controlling the reciprocating movement of the piston on the basis of the travel amount.
