Intake menifold of engine

Abstract

Abstract PURPOSE:To improve the dimensional accuracy and to strengthen the mechanical jointing force, by projecting a filler section integrally from the joint of members split cast through voidless diecast for constructing an intake manifold of an engine then performing TIG welding. CONSTITUTION:An intake manifold for a 4-cylinder engine is assembled with two split cast members 1a, 1b cast from aluminum alloy through voidless diecast. Filler sections 3a, 3b are projected integrally from the joints 2 of said members 1a, 1b. The joint sections 2 are butted each other to weld the filler sections 3a, 3b through TIG welding thus provide reinforcement of weld.
