Air intake attachment for improved combustion, in IC engine

摘要

The attachment (9) comprises a cartridge (11) which holds solid naphthalene (12), e.g. in ball form, so that it is located across the intake air flow and carries naphthalene gas vapours via holes (13) to mix with the fuel vapours going to the combustion chamber. The cartridge is mounted on a support (10) which is preferably detachable and in the form of a grille and it can be in the form of a series of tubes filled with naphthalene balls and pierced with holes. The inner diameter of the tubes is slightly greater than the diameter of the balls, and the number of balls is such that the weight of naphthalene is not more than 5 mg per litre of air passing through the intake during the operation of the engine or burner.
