摘要： A blow-by gas recirculation structure includes a cylinder head (3) including an intake manifold mounting surface (3d) and a cylinder block mounting surface (3e) with a first intake passage (21A) extending between a first intake opening formed in the intake manifold mounting surface (3d) and a first intake port (10) formed in the cylinder block mounting surface (3e), and a second intake passage (21B) extending between a second intake opening formed in the intake manifold mounting surface (3d) and a second intake port (10) formed in the cylinder block mounting surface (3e). The cylinder head (3) further includes at least one blow-by gas passage (22) for recirculating blow-by gas to the first intake passage (21A). The intake manifold mounting surface (3d) has at least one enlarged recess (25a) fluidly connected between the blow-by gas passage (22) and the first intake passage (21A), the enlarged recess (25a) being disposed between the first and second intake openings and at least partially aligned with centers of the first and second intake openings.

摘要： A cylinder head (3) includes a lifter guide boss part (12), a concave relief groove portion (13) and a guide portion (14, 14'). The lifter guide boss part (12) defines a lifter bore (12a) arranged to slidably support a valve lifter (9). The concave relief groove portion (13) has a predetermined width and a predetermined depth formed on the lifter guide boss part (12) in a position corresponding to a rotation direction of a cam (8) to avoid an interference between the cam (8) and the lifter guide boss part (12). The relief groove portion (13) includes a pair of groove side surfaces (13c) and a groove bottom surface (13b) with a pair of corner sections (13a) being formed between the groove bottom surface (13b) and the side groove surfaces (13c). The guide portion (14, 14') protrudes from the groove bottom surface (13b) in a sliding direction of the valve lifter (9) to slidably guide the valve lifter (9). The guide portion (14, 14') is spaced apart from the corner sections (13a) of the relief groove portion (13).
摘要翻译：气缸盖（3）包括升降器引导凸台部（12），凹形凸出槽部（13）和引导部（14,14'）。提升器引导凸台部分（12）限定了一个升降器孔（12a），其布置成可滑动地支撑气门挺杆（9）。所述凹形释放槽部（13）具有在与所述凸轮（8）的旋转方向对应的位置上形成在所述升降器引导凸台部（12）上的预定宽度和规定深度，以避免所述凸轮（8）和升降器引导凸台部（12）。所述止动槽部（13）具有一对槽侧面（13c）和槽底面（13b），在所述槽底面（13b）与所述侧槽面（13b）之间形成有一对角部（13a） 13C）。引导部分（14,14'）沿着阀提升器（9）的滑动方向从槽底表面（13b）突出，以可滑动地引导气门挺杆（9）。引导部分（14,14'）与释放槽部分（13）的角部（13a）间隔开。
