ノズルスリーブを有する多気筒エンジンのシリン
ダヘツドにおいて、前記各スリーブを結ぶ直線状
の冷却水往路とヘツド内の冷却水復路とを連通せ
しめる上記スリーブ周縁部に設けた冷却水出口穴
を、偏在させて排気側は多く吸気側が少なく開口
してなる多気筒エンジンのシリンダヘツド。 In a cylinder head of a multi-cylinder engine in which a plurality of four-valve cylinders are arranged in parallel and each cylinder has an injection nozzle sleeve at the center thereof, the linear cooling water outward path connecting each sleeve communicates with the cooling water return path in the head. A cylinder head for a multi-cylinder engine in which the cooling water outlet holes provided on the peripheral edge of the sleeve are unevenly distributed, with more openings on the exhaust side and fewer openings on the intake side.
