  • the air intake device of the engines internal combustion conventionally includes a collector admission also called dispatcher who has for function to port the filter output air, and the entrance of the various intake ducts in the cylinder head of the engine.
  • a collector admission also called dispatcher who has for function to port the filter output air, and the entrance of the various intake ducts in the cylinder head of the engine.
  • the intake manifold presents classically a body coming to be fixed on the cylinder head of the engine; this body generally comprises a distribution chamber large capacity also called plenum and several pipes that leave this distribution chamber to supply combustion air to each of the combustion chambers of the engine.
  • the intake manifold of a combustion engine internal is usually connected to a number more or less important of depression taken serving to operate organs as diverse as the braking system or Master Vac, the EGR valve, the fuel return valve fitted to the injection rail, systems for adding non-combustible substances or secondary combustible substances crankcase gases, fuel vapors from the canister or recirculated flue gases, as well as the sensor for measuring the manifold pressure.
