LEAN-BURN INTERNAL COMBUSTION ENGINE

摘要

An adaptor (114) for mounting a cylinder head (116) of a lean-burn internal combustion (IC) engine (102) is described. In an embodiment, the adaptor (1 14) includes a body portion (118) having a hollow cylindrical shape for mounting the adaptor on an engine block (104), the body portion (118) being adapted for mounting the cylinder head (116). Further, the adaptor (114) includes a cylinder head partition (120) coupled to the body portion (118). When the cylinder head (1 16) is mounted on the body portion (118), the cylinder head partition (120) bifurcates an intake passage (122) formed by a central cavity of the cylinder head (116).
