    • The invention relates to an internal combustion engine (1) comprising a cylinder crankcase (2) and a cylinder head (3) that comprises an integrated exhaust manifold (4), wherein the cylinder crankcase (2), the cylinder head (3) and the integrated exhaust manifold (4) have a continuous water cooling jacket (12) that forms part of a coolant circuit (6) of the internal combustion engine (1). In order to ensure during shut-down cooling and/or warm-up cooling of the exhaust manifold (4) that a majority of the coolant that is fed into the water cooling jacket (12) reaches the exhaust manifold (4), while only a small portion of the coolant flows around the cylinder through the cylinder crankcase (2), according to the invention the coolant circuit (6) comprises a collector (27) that communicates via though-openings (38) having reduced opening cross-sections with the water cooling jacket (12), and coolant channels (39) arranged in extension of a flow direction through the through-openings (38) lead to the exhaust manifold (4), while coolant channels (32) branching off laterally behind the through-openings (38) lead to the cylinder crankcase (2).

    • The upper parts of the cylinder liners and the cylinder head are formed integral in one piece, and a water jacket is provided around the outer peripheries of the upper parts of the cylinder liners, with no water jacket provided to the cylinder body. This eliminates the use of the core for the water jacket in molding the cylinder body, which in turn reduces the engine weight, brings about a significant cost reduction and makes machining operations easy. Because the piston head is made of a heat insulating material and a water jacket is not provided to the cylinder body, the heat is prevented from flowing down to the cylinder liners. Furthermore, the cylinder liners are made of a ceramic material to improve an anti-galling characteristic during sliding motions at high temperatures. Also, since the water jacket is provided only to the cylinder head, the water jacket can be made simple and small in structure, reducing the cooling water flow resistance. This in turn permits the use of a small motor-powered water pump that can be controlled independently of the engine conditions. Moreover, since the cylinder body has no water jacket, there is a greater freedom in designing the cylinder body, which makes it possible to form reinforcement ribs on the cylinder body to increase its rigidity and thereby reduce vibrations and noise.
    • 气缸套和气缸盖的上部一体形成一体,并且在气缸套的上部的外周周围设置水套,没有向气缸体提供水套。 这消除了在模制气缸体时使用水套的芯部,这又降低了发动机重量,导致显着的成本降低并且使加工操作变得容易。 由于活塞头由绝热材料制成,并且水套不设置到缸体,所以防止了热量向下流动到气缸套。 此外,气缸套由陶瓷材料制成,以在高温下的滑动运动期间提高抗磨损特性。 此外,由于水套仅设置在气缸盖上,所以可以使水套的结构简单,结构小,降低了冷却水的流通阻力。 这又允许使用可以独立于发动机条件进行控制的小型电动水泵。 此外,由于缸体没有水套,因此在缸体的设计上具有更大的自由度,这使得可以在缸体上形成加强肋,以增加其刚性,从而减少振动和噪声。
