4.1.8. Starting arrangement OVAD
Installation of the auxiliary valve приоткрывания a starting diaphragm
The auxiliary valve приоткрывания a starting diaphragm (the work scheme)
The mechanism has двухмембранную with разряжением a control system приоткрыванием, and also a receiver разряжения and a socket. Work The engine cold, the starting arrangement is included, springs push membranes in a direction of the case of the carburettor and influence a management shaft, the starting diaphragm is closed. During engine start разряжение in an inlet tube influences membrane М1 which leans against membrane М2. Разряжение does not influence membrane М2 immediately because of use of the calibrated jet in pass between the chamber and a receiver. The starting diaphragm is slightly opened, but in such degree that enrichment immediately increases. Разряжение reaches the second chamber and works a receiver, the spring is compressed by a membrane, the shaft of management of a starting diaphragm can move till the end of the course, and the starting diaphragm opens completely.
In cars with an automatic transmission the external chamber is connected to a support of the carburettor by means of the valve of delay and the calibrated jet. |
