Air inlet arrangement for internal-combustion engines, particularly fuel injection combustion engines

Abstract

Abstract 1. An air-intake installation for internal combustion engines, especially injection-type internal combustion engines, - with U-shaped individual intake pipes (4 to 9) of substantially equal length which are arranged in a row side by side and which issue from a manifold housing (2) extending parallel to the axis of the engine - the individual intake pipes having inlet radii (12, 13) at the openings (11) in the manifold housing, characterized - in that the individual intake pipes (4 to 9) lie closely side by side in the region of their U-form cross-pieces (4', 5', 6', 7', 8', 9') with an overall dimension which is smaller than the overall length of the manifold housing (2) which, in turn, is less than the maximum interval of the connections (10) of the outer inlet passages of the engine, while the distances between the individual intake pipes increase towards the openings (11) by the inlet radii (12, 13). - while the U-form legs (4'', 5'', 6'', 7'', 8'', 9'') connected with the openings (11) have different lengths to compensate for the different lengths of the U-form legs (4''', 5''', 6''', 7''', 8''', 9''') extending to the engine.
