These new intake manifolds are supplied split up: the intake rubber can be rotated into the flange according to the specific requirements of the vehicle, in order to locate which is the best angle for the carburettor assembly.

INTAKE MANIFOLDS Intake manifold conveys the air-fuel mixture to the engine by means of reed valve. The total efficiency of an engine is calculated as the product of various partial efficiencies, such as: volumetric efficiency thermodynamic efficiency mechanical efficiency Volumetric efficiency is the ratio between the quantity of fuel that can enter the combustion chamber and the displacement of the engine. One of the main factors affecting volumetric efficiency is loss due to friction that the fluid encounters (air-fuel mix) when feeding from the air filter to the combustion chamber.…
