9.2. General informationThe power supply system fuel consists of the STROMBERG or PIERBURG carburetor, a fuel tank, the mechanical fuel pump, fuel pipelines, the air filter and the fuel filter of the cartridge type established in a fuel tank.On the Sedan models the fuel tank is located before a luggage compartment, and on the Versatile person models is located under a trunk floor. Fuel from a fuel tank via the fuel filter and the pipeline gets the fuel pump and further under pressure moves in the poplavkovy chamber of the carburetor. The float and the needle valve regulate fuel level in the poplavkovy chamber. Surpluses of fuel on returnable топливопроводу come back to a fuel tank. The air filter established on a cover of a head of the block of cylinders or on the carburetor, contains a replaceable filtering element. In front of the air filter the temperature regulator with a zaslonka is established. The temperature regulator maintains temperature some air arriving in the engine at an optimum level because the zaslonka operated by a temperature regulator, provides or receipt in the engine of cold air, or the air which has been warmed up by a final collector. At cars supply of fuel at start of the cold engine and turns of idling cope with the STROMBERG CD T175 carburetor the delay valve. The valve consists from биметалличес which strips which heats up an electric current passed through it and operates vacuum in the case of a diaphragm of an operating zaslonka. At start of the cold engine the valve of a delay blocks vacuum to a diaphragm and the zaslonka remains closed. In the course of warming up of a bimetallic plate after engine start the vacuum gradually increases, and a zaslonka, opening, regulates idling turns. Also there is an electromagnetic valve, перекрыва yushchiya supply of fuel. This valve excludes operation of the engine after ignition switching off, and also limits the maximum turns of the engine, blocking supply of fuel if turns of the engine exceed the most admissible.
