Cylinder cover for e.g. petrol engine, has connection including connecting surface extending between lateral surface of housing and cylinder head and presenting inclined pan inclined along part of front edge of inlet orifice

摘要

The cover has an intake duct (1) defined by a surface (50) including curved interior and exterior parts (51, 52). An inlet orifice (6) has a front edge (AV) extending with respect to a symmetry axis (Z2) of a housing (26) on a semi-circumference located from a side of the exterior part of the curved portion of the surface delimiting the duct. A Connection (71) includes a connecting surface (70) extending between a lateral surface (29) of the housing and a cylinder head (2), and presents an inclined pan (4) inclined along a part of the front edge of the orifice.
