Weber 2V Carburetor
Weber 2V vertical flow carburetor with automatic choke. Sequential throttle opening.
Weber dual-barrel carburetors are installed on OHC and DOHC engines.
The carburetor has main metering systems in the first and second chambers, an idle system of the first chamber, transition systems of the first and second chambers, an economizer of power modes, an accelerator pump, an automatic starting device and an electric heater of the intake air.
The second chamber throttle valve is controlled by the vacuum created in the primary chamber.
Heating of the automatic air damper is electric only. The vacuum return device for opening the damper is a single unit with the housing.
A distinctive feature of the carburetor is the stepper motor that controls the position of the throttle valve. This motor is controlled by the electronic ignition control module MK II (ESC II module) and maintains idle stability, and also controls the position of the throttle valve when reducing speed, starting and stopping the engine. As a result, optimal fuel consumption and low CO levels are achieved.
