摘要： PROBLEM TO BE SOLVED: To provide an icing prevention device capable of warming a vaporizer and effectively inhibiting a generation of icing without consideration to corrosion by a warming fluid for warming the vaporizer and inhibiting a function of the vaporizer. SOLUTION: The icing prevention device is provided with the vaporizer V for reducing a pressure of a gas fuel in a gas fuel source to the approximately atmospheric pressure state; and a forced-feed lubrication mechanism K for suctioning a lubricant in an oil pan 31 to an oil pump 33, feeding the lubricant of which the pressure is increased at the oil pump 33 to an oil cooler 35 and recirculating the lubricant into the oil pan 31 after the lubricant retained to an appropriate temperature at the oil cooler 35 is fed to a slide part of an engine. A part or a whole of the lubricant flowing in the forced-feed lubrication mechanism K is circulated into a casing of the vaporizer V.

摘要： PROBLEM TO BE SOLVED: To provide a vaporizer capable of stably carrying out an operation of an engine without temporarily shielding feed of a gas fuel and diluting a concentration of air-fuel mixture at the time of snap action of a throttle valve. SOLUTION: The vaporizer V reduces a pressure to a predetermined primary pressure at a primary pressure reduction chamber and adjusts the pressure to a secondary pressure in the approximately atmospheric pressure state at a secondary pressure reduction chamber 36. A slow lock valve 28 for opening/closing a primary fuel deliver passage 27 is disposed at the delivery passage 27 opened from the primary pressure reduction chamber 22 and a slow lock pressure receiving chamber 30 divided by a slow lock diaphragm 29 for imparting an opening/closing operation force to the slow lock valve 28 and a suction passage 40 are communicated by a negative pressure introduction. A pressure control valve P is disposed at the introduction passage. The pressure control valve P is divided to an upstream chamber PA and a downstream chamber PB and is communicated by a by-path passage 3 bypassing a valve hole 2 and a valve hole 2. A check valve 6 is disposed facing to the valve hole and opens the valve hole 2 when the negative pressure of the suction passage 40 acting on the upstream chamber PA is a constant value or higher and it closes the valve hole when the negative pressure is a constant value or lower. A control orifice 7 is disposed at the by-path passage 3 and the upstream chamber PA and the downstream chamber PB are always communicated by the control orifice 7.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas recirculating device for smoothly distributing exhaust gas, having improved sealing performance in such a fully closed condition that a passage for exhaust gas to be distributed is closed while preventing the fixation of a valve mechanism due to the deposition of combustion products in exhaust gas.
SOLUTION: The valve mechanism 18 includes a disc-like valve 42, a holder 46 on which the valve 42 is mounted, and first and second shafts 38, 48 provided at both ends of the holder 46. The second shaft 48 is turned via a gear mechanism 20 under the driving operation of a driving part 16, whereby the holder 46 and the valve 42 are integrally turned and displaced. On the outer peripheral face of the valve 42, a seal ring 44 is mounted which includes resilient force outward in the radial direction. When the valve 42 is turned and displaced to close a communication passage 12, the seal ring 44 is seated on a valve seat portion 32 of a valve seat 30 to establish such a fully closed condition that the communication of the communication passage 12 is cut off.

摘要： PROBLEM TO BE SOLVED: To provide a flow passage opening/closing valve which maintains hermeticity of a valve element and is rich in durability.
SOLUTION: An EGR valve 20 includes a body 22, a ball valve 30, a shaft 90, a valve presser 32 coming into contact with the ball valve 30 and a valve seat 37. An annular groove 43 is formed between a small-diameter portion 34 and large-diameter portion 36 of the valve presser 32 and has a diameter smaller than the small-diameter portion and large-diameter portion have. A chamber 33 is formed between the annular groove 43 and body. Since a combustion product of exhaust gas is deposited on the chamber 33 when entirely closing the ball valve 30, the hermeticity between the ball valve 30 and exhaust gas flow out port 26 can favorably be maintained for the long term.

摘要： PROBLEM TO BE SOLVED: To provide an output control device for a two-wheeled vehicle, capable of controlling output of an internal combustion engine under consideration of a load added to the two-wheeled vehicle (passenger weight) to set acceleration and deceleration to variation of accelerator opening (operation quantity to accelerator grip) regardless of size of the load, and improving operation feeling. SOLUTION: On a front suspension and a rear suspension of the two-wheeled vehicle, a front stroke sensor and a rear stroke sensor are respectively disposed. Based on front stroke quantity STF and rear stroke quantity STR as their detection values, a total load Lweight based on the passenger weight PW and road surface gradient Rangle is estimated (S10 and S12). Based on the estimated load Lweight, target throttle opening THd is determined (by correcting basic throttle opening THbs determined in accordance with accelerator opening θA), and engine output is controlled (S14-S18).
