Carburetor Pierburg 2E2
On the engines of the DS and DT models, a Pierburg 2E2 emulsion-type carburetor was installed, two-chamber, with sequential opening of the throttle valves.
The carburetor has two main metering systems of the 1st and 2nd chambers, an idle system of the 1st chamber with a transition system, a transition system of the 2nd chamber, an economizer of power modes, an eco-nostat, a diaphragm accelerator pump, an automatic starter and mixed-type heating, which uses an electrically heated bimetallic spring and the circulation of heated liquid from the engine cooling system, and uses an air damper pneumatic actuator and an electric heating device for the intake piping. The carburetor has a pneumatic actuator of the throttle valve of the 1st chamber, which controls its movements in idle and forced idle modes, as well as a pneumatic actuator of the throttle valve of the 2nd chamber. At forced idle, the forced idle economizer is activated.
