Intake and exhaust manifold

The inlet manifold serves to supply the combustible mixture from the carburetor to the engine cylinders. They are usually cast from aluminum alloys. Inlet pipelines are heated with coolant or exhaust gas, which contributes to the evaporation of the fuel film.

The exhaust pipe is designed to exhaust gas to the exhaust pipes and silencer. The exhaust pipe is cast from cast iron. The heat of the exhaust gases is used to heat the combustible mixture at the outlet. For this purpose, the inlet and outlet pipelines are connected by studs through an iron asbestos gasket.
