Below at first explanatory drawing 1 to claim 1 to 3,15 to 18 said one embodiment of the present of invention (first embodiment) of the application shown in Figure 4.
In these figure, 1 is motor-scooter type moped for what be suitable for using with the device to the vent systems feeding secondary air of the present embodiment shown in the left side view 1, and 2 is vehicle seat, separates with low chassis portion 3 in its place ahead, has a steering head 4 upright.The handle rotating shaft 6 of rotating with handle 5 is bearing on the head pipe 7, in its lower end, by front fork 8 suspension front-wheels 9.From the beginning following vehicle frame 10 is managed 7 and is extended downwards, rearward extends from chassis portion 3 behind the bifurcated of the left and right sides, bottom, then is connected with back vehicle frame 11.This back vehicle frame 11 tilts and up rearward extends, and arrives the rear end lower of vehicle seat 2.
Down be provided with the rear portion of topped vehicle frame 10 down and along its leg guard 12, this leg guard 12 extends to the rear lower side in vehicle frame 10 and back vehicle frame 11 front portion that forms the vehicle body of bone by these, cover 13 with the chassis of chassis portion in the middle of the topped vehicle body and be connected.And, this chassis cover 13 rises to oblique rear from level, link to each other with the topped vehicle body cover 14 of the rear prolongation of vehicle frame 11 afterwards, and this vehicle body cover 14 links to each other with intermediate cap 15 with its front upper place part, and this intermediate cap 15 covers the place ahead part of the fuel tank 16 that is contained in vehicle seat 2 belows with this vehicle seat 2.
The 17 internal-combustion engine units of using for Rear wheel suspension (swing unit), its front portion can be contained in the lower front of back vehicle frame 11 by suspension rod 18 with swinging up and down, and simultaneously, its rear portion then is suspended on the rear portion of back vehicle frame 11 by vibration damper 19.
Front portion at internal-combustion engine unit 17 is provided with internal-combustion engine 20 integratedly, at the rear portion, with axle supporting wheels 21.And the power transmitting deice (variable v-belt drive) 22 of the power of internal-combustion engine 20 being passed to trailing wheel 21 is that baffler 28 is clipped in the middle trailing wheel 21 with an element that constitutes the aftermentioned vent systems, is located at integratedly on the internal combustion engine component 17.
Internal-combustion engine 20 is two-cycle IC engines, and the suction system of being made up of air-strainer 23, vaporizer 24 and sucking pipe 25 links to each other with the intakeport (not shown) of internal-combustion engine 20.
In baffler body 30, as shown in Figure 2, store by the catalytic converter of being made up of the metal catalytic material 32, the discharge gas of deriving by outlet pipe 27 carries out oxidation reaction in this catalytic converter 32, become the gas of perfect combustion, be disposed in the atmosphere with the state that is cleaned.
In aforementioned vent systems, further import secondary air, just improved the gas cleaning effect of discharging by aforementioned catalytic converter 32.This secondary air is supplied with by secondary air supply described later from secondary air introducing port 34, this secondary air introducing port 34 be formed on outlet pipe 27 and internal-combustion engine 20 relief opening 26 attachment portions near.
The air-strainer 35 that aforementioned secondary air air supply system is used by vent systems, the safety check of forming by leaf valve 36, and they are coupled together and the secondary air supplying pipe 37 that they are connected on the aforementioned secondary air introducing port 34 is formed.Secondary air supplying pipe 37 is by connecting flexible rubber flexible pipe 38 with leaf valve 36 of air-strainer 35 that vent systems uses, being connected the flexible rubber flexible pipe 39 of leaf valve 36 sides of leaf valve 36 and secondary air introducing port 34 and the metal tube 40 of secondary air introducing port 34 sides constitutes.
Consisting of of the air-strainer 35 that aforementioned vent systems is used: make its air suction inlet 35a towards the front lower place, use the connected element of forming by screw bolt and nut 42 to be installed in the rear portion of the vertical fixing vertical installation sheet 41 of the cockscomb shape in the top of baffler main body portion 30 (referring to Fig. 4), the 35b of purifying chamber one side that its air cleaningization is indoor, be divided into two chambers with dividing plate 35c, this two Room is communicated with connecting tube 35d, the air that is filtered peace and quietization of device 35e enters this two Room, 35f comes out from outlet, imports rubber hose 38 parts of secondary air supplying pipe 37.
The connected element 44 that aforementioned leaf valve 36 usefulness are made up of screw bolt and nut is installed on two wrist 43a, the 43b that the substantially horizontal of the installation sheet 43 on the place ahead wide width part that is fixed in vertical installation sheet 41 stretches out.
And, the air-strainer 35 that these vent systems are used is heat insulation by muffler cover 45 and baffler body portion with leaf valve 36, this muffler cover 45 is assemblied in the groove 45a at its top on the 41a of welding foot of vertical installation sheet 41, separates certain distance, is contained on the baffler body portion 30.
Also have, owing to can freely set shape, the capacity of the air-strainer 35 that vent systems uses, for example, make cylindrical shape, capacity is strengthened, the side of the 35b of purifying chamber that it is indoor is separated into a plurality of chambers of a series of connections, then can eliminate the exhaust sound of the internal-combustion engine 20 that reaches the air-strainer 35 that vent systems uses and the chatter of leaf valve 36 effectively.
Also have, because the air-strainer 35 used of vent systems is 30 swings of baffler body portion with the part of the internal-combustion engine unit 17 of swing all with leaf valve 36, so the each several part 38,39,40 of the secondary air supplying pipe 37 that air-strainer 35, leaf valve 36 and secondary air introducing port 34 that vent systems is used are connected with each other needn't be made and can absorb produced by the swing of internal-combustion engine unit 17 flexible, the length and the whole length of its each several part 38,39,40 can be done shortly.
Have again, be arranged on the baffler body portion 30 because the air-strainer 35 that vent systems is used is all concentrated with leaf valve 36, so whole secondary air-supply device can be very compact.
