ARRANGEMENT OF EVAPORATED FUEL COLLECTING DEVICE
FIELD OF THE INVENTION
[OOl] The present invention relates to a two-wheeled vehicle incorporating an
evaporated fuel collecting device.
BACKGROUD OF INVENTION
[002] Apart from the exhaust emissions froin the two wheeled vehicles, evaporative emissions
need to be controlled and the same can be achieved by employing the evaporated fuel collecting
device. The said collecting device entraps the gaseous fuel vapours generated in the fuel tank and
supplies them to the carburettor.
[003] The performance of the evaporated fuel collecting device depends on the charging and
purging efficiency which in turn depend on the temperature to which evaporated fuel collecting
device is exposed to. The charging efficiency has an inverse relationship with the temperature
whilst the purging efficiency has a direct relationship with the temperature of the retention
, apparatus. The temperature of the evaporated fuel collecting device is dependent on factors such
as proximity to the internal combustion engine, exhaust pipe, direct exposure to the sunlight and
exposure towards the wind or airflow.
[004] The saddle type vehicle such as motorcycle does not have much space or room to
accommodate the evaporated fuel collecting device with great flexibility such that the layout and
arrangement of the evaporated fuel collecting device becomes restricted.
OBJECT OF MVENTION

a two wheeled vehicle to ensure safety of the user of the vehicle and reducing wear-tear of the
evaporation fuel collecting device, while managing space constraint within the vehicle and
avoiding disturbance of extreme boundaries of the vehicle.

purging efficiency which in turn depend on the temperature to which evaporated fuel collecting
device is exposed to. The charging efficiency has an inverse relationship with the temperature
whilst the purging efficiency has a direct relationship with the temperature of the retention
, apparatus. The temperature of the evaporated fuel collecting device is dependent on factors such
as proximity to the internal combustion engine, exhaust pipe, direct exposure to the sunlight and
exposure towards the wind or airflow.
[004] The saddle type vehicle such as motorcycle does not have much space or room to
accommodate the evaporated fuel collecting device with great flexibility such that the layout and
arrangement of the evaporated fuel collecting device becomes restricted.

provision (159) of evaporated fuel collecting device At least one of the leg unit from
among the leg units (162) & (163) of U-shaped anchor (161) is inserted into the
provision of anchor accommodating member (160) so as to mount the evaporated fuel
collecting device (1 13) into the first compartment (143) of the integrated assembly (134)..
In an embodiment, the leg units (162) and (163) of U-shaped anchor (161) are inserted
into anchor accommodating member (160). The second lid member (142) then removably
covers the second opening (140) of the integrated assembly (134) after the evaporated
he1 collecting device (1 13) is disposed into the first compartment (143). After the
14
HPO D E t K H 2 8 - E l 1 - 2 Q P 5 1 G ; S E
evaporated fuel collecting device (1 13) is disposed within the first compartment (143),
the charge pipe and purge pipe are inserted within the slots (166) and (167) provided on
the first lid member (141). The charge pipe and purge pipe after being inserted into the
slots (166) and (167) are then connected to respective charge pipe provision (157) and
purge pipe provision (158). The first lid member (141) is then moved towards the
integrated assembly (134) and then it covers the first opening (139) of the integrated
assembly (1 34).
[0055] Such an arrangement of evaporated fuel collecting device (1 13) into the
integrated assembly (134) would minimize the effects of vibration and reduce rattling of
evaporated fuel collecting device (1 13).
[0056] In another embodiment, the evaporated fuel collecting device (1 13) is disposed in
the first compartment (143) of the integrated assembly (134) through at least one guide
, rail, provided on the at least one side face (155) of the evaporated fuel collecting device
(1 13). The guide rail extends along the length of evaporated fuel collecting device (1 13).
In an embodiment, at least one guide rail is integrated with the side face (155) of the
, < evaporated fuel collecting device (1 13). At least one slide rail is provided in the first
compartment (143). The slide rail extends from the first opening (139) towards the
second opening (140), partially or completely, of the integrated assembly (134). The
evaporated fuel collecting device (1 13) is disposed inside the first compartment (143) by
sliding the guide rail on the slide rails such that second face (154) of the evaporated fuel
collecting device (1 13) approaches the second lid member (1 42) as the, e-vaporated fuel
collecting device (1 13) is slid into the first compartment (143). In an embodiment, the
evaporated fuel collecting device (1 13) gets locked up when the complete guide rail is
accommodated within the slide rail.
[0057] In accordance with the present invention described above, the evaporated fuel
collecting device (1 13) is disposed within the integrated assembly (134), and accordingly
the length of purge pipe, charge pipe and air intake pipe is shortened thereby increasing
the flexibility of layout of evaporated fuel collecting device.
