    • The invention relates to an internal combustion engine having a piston-cooling arrangement (1) which has at least one spray device (2, 27; 2, 39) which is supplied with a coolant/lubricant via at least one supply passageway (3). The supply passageway (3) is arranged in a module (4) composed of a crankshaft-bearing structural element (6) and a crankshaft-bearing cap (7). The spray device (2, 27; 2, 39) is coupled to the crankshaft-bearing cap (7), a crankshaft-bearing shell (14) in the region of the supply passageway (3). Supply passageway (3) also connect to through-opening (16), so that coolant/lubricant can be directed via the supply passageway (3) to both the spray device (2, 27; 2, 39) and a crankshaft (17). The spray device (2) is designed as an oil-spray nozzle (27) or alternatively as a spray hole (39) integrated in the crankshaft-bearing cap (7).
    • 本发明涉及一种具有活塞冷却装置(1)的内燃机,该活塞冷却装置具有经由至少一个供应通道(3)供应有冷却剂/润滑剂的至少一个喷射装置(2,27; 2,39) 。 供给通道(3)布置在由曲轴轴承结构元件(6)和曲轴轴承盖(7)组成的模块(4)中。 喷雾装置(2,27; 2,39)在供给通道(3)的区域中连接到曲轴轴承盖(7),曲轴轴承壳(14)。 供应通道(3)还连接到通孔(16),使得冷却剂/润滑剂可以经由供应通道(3)被引导到喷雾装置(2,27,23)和曲轴(17); 。 喷射装置(2)被设计为喷油嘴(27),或者作为集成在曲轴轴承盖(7)中的喷孔39)设计。

    • A hybrid cooling system for an engine is provided. The system comprises a block oil cooling circuit, a head coolant cooling circuit, the head and block circuits having a common heat exchanger. The system also includes a flow device in the head cooling circuit for preventing coolant flow in the head cooling circuit at least during a first phase of a warm-up phase of the internal combustion engine, a delivery device in the block cooling circuit which delivers engine oil constantly under pressure through the block cooling circuit to bearing points in a cylinder block and to bearing points in a cylinder head, and a control element arranged in a control line to reduce the delivery capacity of the delivery device through the block cooling circuit at least during the first phase of the warm-up phase. In this way, heat transfer in the common heat exchanger may be substantially prevented.
    • 提供了一种用于发动机的混合冷却系统。 该系统包括块油冷却回路,头部冷却剂冷却回路,头部和块状回路具有共同的热交换器。 该系统还包括头部冷却回路中的流动装置,用于至少在内燃机的预热阶段的第一阶段期间防止冷却剂在头部冷却回路中的流动;块冷却回路中的输送装置,其输送发动机 在压力下通过块体冷却回路将油保持在气缸体中的轴承点和气缸盖中的轴承点,以及布置在控制线中的控制元件,以至少通过块冷却回路减少输送装置的输送能力 在预热阶段的第一阶段。 以这种方式,可以基本上防止公共热交换器中的热传递。
