And, the major part on 2 air supply pipe roads 86, the line of centers C2 across the Width center of passing main car frame 13 is configured in the opposition side of carburettor 38.
2 secondary air control valves 48 like this are fixed on the main car frame 13 of vehicle body frame F.That is, strut bar 87 is attached at the side of main car frame 13, and the pivot flange 58a and the above-mentioned strut bar 87 that are wholely set on housing 58 link, and contact with this strut bar 87 from the below.
Be configured in the Fuel Tank 25 and the carburettor 38 that is configured in the front lower place of this Fuel Tank 25 of the below of dual seat 26, connect by the fuel feed line 88 that extends to the front lower place from Fuel Tank 25 beginnings, the negative pressure of the air-intake negative-pressure action by driving engine E is made the fuel plug valve 90 of dynamic formula, is arranged on this fuel feed line 88 midway.
In Fig. 6, fuel plug valve 90 has: shell 91, by the barrier film 92 of these shell 91 clamping circumferences, be fixed on valve body 93 on the central portion of this barrier film 92, be arranged on the pull back spring 94 between shell 91 and the barrier film 92.
Shell 91 is made of housing 95 and cover 96, the circumference of these cover 96 mutual above-mentioned barrier films 92 of clamping airtightly, and riveted joint is combined on this housing 95, and the negative pressure chamber 97 that faces the one side of this barrier film 92 forms between cover 96 and barrier film 92.And in negative pressure chamber 97, spring stop 98 contacts with the inner face of cover 95, and pull back spring 94 compressions are arranged between barrier film 92 and the spring stop 98, and performance makes barrier film 92 increase the elastic force of the bending direction of side to the volume that makes negative pressure chamber 97.
The connection pipe portion 99 that is communicated with negative pressure chamber 97 is wholely set on cover 96, takes out pipeline 100 by negative pressure between the air inlet pipe 39 of this connection pipe portion 99 and air inlet system 40 and connects.That is, the negative pressure in the air inlet pipe 39 is imported into negative pressure chamber 97.
Between above-mentioned barrier film 92 and housing 95, form valve chamber 101, housing 95 is provided with valve seat 102 and valve opening 103, this valve seat 102 can make 93 of valve bodies on the central portion that is fixed on above-mentioned barrier film 92 go into, and this valve opening 103 is at the central portion downstream end opening of valve seat 102.And, among fuel feed line 88, the pipe section 88a that links between Fuel Tank 25 and the fuel plug valve 90 is connected on the housing 95, be communicated with valve opening 103, among above-mentioned fuel pipeline 88, the pipe section 88b that links between carburettor 38 and the fuel plug valve 90 is connected on the housing 95, is communicated with above-mentioned valve chamber 101.
Also have, the installation strut bar 39a that reaches fuel plug valve 90 sides is wholely set on air inlet pipe 39, flange portion 95a is attached on the stay bearing plate 104, and this stay bearing plate 104 is attached on this installation strut bar 39a, and this flange portion 95a is wholely set on the housing 95 of above-mentioned fuel plug valve 90.That is, fuel plug valve 90 is installed on the air inlet pipe 39.Like this, under the state that is installed on the air inlet pipe 39, fuel plug valve 90 is configured in the side of 2 secondary air control valves 48 below main car frame 13, across main car frame 13, is configured in the opposition side with carburettor 38.
In addition, air-out feed pipe 105 is arranged between airfilter 37 and the carburettor 38, this air-out feed pipe 105 imports carburettor 38 with air-out, air-out is arranged on this air-out feed pipe 105 midway with fil 106, is configured in the top of above-mentioned 2 airfilters 79.
Then, effect with regard to this embodiment describes, control is to the exhaust of the exhausr port 44 of driving engine E 2 secondary air control valves 48 with the supply of 2 air, be disposed at driving engine E above air inlet system 40 carburettor 38 and be installed between the actuating motor 50 on top of driving engine E, be configured between driving engine E and the main car frame 13, this driving engine E leans forward cylinder axis C1, is configured in the below of main car frame 13.
Therefore, between driving engine E that cylinder axis C1 is leaned forward and main car frame 13, on the space that produces respectively between carburettor 38 and the actuating motor 50, can dispose 2 secondary air control valves 48 effectively.And, because 2 secondary air control valves 48 be configured in driving engine E near, so can make 2 air supply pipe road 86 cripeturas between the exhausr port 44 that links 2 secondary air control valves 48 and driving engine E.
In addition, with 2 secondary air control valves 48,2 airfilters 79 of side bonded assembly at its upstream, line of centers C2 across the Width center of passing main car frame 13, be configured in the opposition side of carburettor 38, carburettor 38 and 2 airfilters 79 can be configured to effectively in the small space between driving engine E and the main car frame 13, so that carburettor 38 and 2 airfilters 79 are configured on the position of the Width that departs from vehicle body frame F.
Have again, because the major part on 2 air supply pipe roads 86, the line of centers C2 across the Width center of passing main car frame 13 is configured in the opposition side of carburettor 38, so can make carburettor 38 and 2 air supply pipe roads 86 near main car frame 13 sides, configuration compactly.
Have again, negative pressure is made the fuel plug valve 90 of dynamic formula below main car frame 13, be configured in the side of 2 secondary air control valves 48, the fuel plug valve 90 that this negative pressure is made dynamic formula is arranged on to the fuel feed line 88 of carburettor 38 midway, because fuel plug valve 90 is configured in the side of 2 secondary air control valves 48, so can make fuel plug valve 90 near carburettor 38, can shorten negative pressure and take out pipeline 100, this 2 secondary air control valve 48 is configured between carburettor 38 and the actuating motor 50, and this negative pressure is taken out pipeline 100 negative pressure is imported the fuel plug valve 90 from air inlet system 40.
In addition, because fuel plug valve 90, is configured in the opposition side with carburettor 38 across main car frame 13, so can easily carry out the pipe arrangement that fuel feed line 88 and negative pressure are taken out pipeline 100.
And, because fuel plug valve 90 is arranged on fuel feed line 88 midway, this fuel feed line 88 extends to the front lower place from Fuel Tank 25 beginnings, be connected with carburettor 38, even so be accompanied by stopping from the fuel feeding of Fuel Tank 25, air is sneaked in the carburettor 38 and the pipe section 88b between the fuel plug valve 90 that links in the fuel feed line 88, when fuel feeding thereafter, even omit exhaust operation to this pipe section 88b, also can make fuel be full of pipe section 88b as soon as possible, and need not to be used for the part of the Dump valve etc. of exhaust, and can reduce the part kind, can supply fuel to carburettor 38 apace simultaneously.
Have again,,, can increase the degree of freedom of fuel plug valve 90 in configuration so compare with the situation that fuel plug valve 90 is installed on the Fuel Tank 25 because fuel plug valve 90 is installed on the air inlet pipe 39 of air inlet system 40.
More than, embodiments of the invention have been described, the present invention is not limited to the foregoing description, can carry out various design modifications under the situation of being put down in writing in the scope that does not break away from claim of the present invention.
