Position throttle заслонок the carburettor 2105-1107010-20 |
1. Full opening throttle заслонок check turn of levers of their drive in position against the stop. |
2. Size of the maximum opening throttle заслонки the primary chamber (13±0,5 mm) regulate подгибанием the bottom short moustache (fig. Adjustment of position throttle заслонок the carburettor see) lever 3. |
3. Size of the maximum opening throttle заслонки the secondary chamber (15±0,5 mm) regulate заворачиванием or отворачиванием a pneumodrive rod. |
4. Partial opening throttle заслонки the primary chamber at which the top short moustache of the lever 3 will adjoin to the lever 2, should be 6±0,1 mm. This size is regulated подгибанием the top short moustache of the lever 3. |
The starting arrangement |
5. At turn of the lever 1 (fig. Adjustment of a drive of the starting arrangement see) counter-clockwise against the stop air заслонка should be completely closed. And in this position of the lever the end of draught 3 should be in the end of a groove of a rod 4 starting arrangements, but thus not to move a rod. This requirement is carried out подгибанием draughts 3. |
6. At completely closed air заслонке throttle заслонка the primary chamber should be slightly opened on 0,70–0,80 mm (a backlash With – distance between заслонкой and a chamber wall in a place of transitive apertures of system of idling). This backlash is regulated подгибанием draughts 7. |
7. Completely closed air заслонка should open on 5 0,5 mm (backlash) a rod 4 starting arrangements at its moving manually to the right against the stop. This size is regulated by the screw 5. |
Productivity of the accelerating pump |
8. Productivity of the accelerating pump is checked for 10 (ten) full courses of the lever 4 (fig. Adjustment of position throttle заслонок the carburettor see) managements throttle заслонками. The fuel which has left a spray of the pump for these ten courses, gathers in a beaker. Its volume should be 5,25–8,75 sm3. |
9. Before the check beginning make ten trial courses the lever 4 for filling of channels of the accelerating pump. |
Tightness of the needle valve |
10. Tightness of the needle valve is checked at the stand which provides fuel giving to the carburettor under the pressure of 30 КПа (3 m of a water column). After level installation in a control test tube of the stand, its falling is not supposed during 10–15 with. If fuel level in a test tube goes down, it specifies in fuel leak through the needle valve. |
