如图3所示，本实施例的机油供给***包括油底壳1、预供油泵7、机油泵8、机油滤清器2和机油冷却器12，油底壳1设在V形气缸体100的底部，预供油泵7设在油底壳1的前侧，机油泵8设在V形气缸体100的前端左下方位置，机油滤清器2设在V形气缸体100的前端的左上方位置，机油滤清器2设在V形气缸体100的前端的右上方位置，油底壳1内的机油通过预供油泵7向上泵入机油泵8，机油泵8内的机油通过管路向上泵 入机油冷却器12，机油滤清器2包括至少三个滤芯，机油滤清器2和机油冷却器12通过中间管连通，流出机油滤清器2的机油进入V型多缸柴油机的机体主油道，机油冷却器12单独由低温水循环回路来冷却，机油冷却器12上设置有低温水入口121。
本实施例的V型多缸柴油机的机油供给***可以应用于12缸V型柴油机，图3示出一种12缸V型柴油机的整机布置图，该12缸V型柴油机的V形气缸体100上布置有多个呈V形排列的两列气缸孔，该V形气缸体100的两列气缸孔之间的夹角为60度，两列气缸孔外侧的V形气缸体100上分别铸造有与缸孔数目对应的套筒101，该12缸V型柴油机可以采取单体泵控制柴油喷射，多个电控单体泵可以对应安装在套筒101内，该12缸V型柴油机可以采用两侧进气管进气，进气采用增压中冷，中冷器设置两个，且可以采用水冷的方式。
参见图4，该12缸V型柴油机的冷却***包括高温水循环回路和低温水循环回路，低温水循环回路包括后排散热器和低温水泵10，低温水循环回路用来冷却机油冷却器12，高温水循环回路包括前排散热器和高温水泵4，高温水循环回路用来冷却V形气缸体100和多个单体气缸盖。低温水泵10设置在V形气缸体100的前端靠近机油泵8上方的位置，高温水泵4设置在V形气缸体100的前端，高温水泵4和低温水泵10分别处于曲轴皮带轮的上方两侧，低温水泵10、高温水泵4、机油泵8围绕在曲轴皮带轮的四周，曲轴皮带轮分别驱动低温水泵10和高温水泵4，流经V形气缸体100和多个单体气缸盖200的冷却液经出水总管进入前排散热器，出水总管和前排散热器之间连接有三个并联的节温器，节温器设置在V形气缸体100的前端的右上方位置，节温器通过散热器水管与前排散热器连通，散热器水管布置在V形气缸体100的顶部。本方案中的低温水循环回路还用来冷却两个中冷器，相应地，低温水循环回路包括低温水分配器，低温水分配器固定在V形气缸体100的前端靠近曲轴皮带轮上方的位置，设置低温水分配器的目的就是，低温水循环回路可以同时冷却机油冷却器12和两个中冷器。至此，如图4所示，本实施例提出的采用高低温水分开冷却，低温水冷却两个中冷器和机油冷却器12，高温水冷却气缸体与气缸盖，该冷却***属于强制闭式循环水冷却***，冷却液应采用防冻、防锈冷却液。采用高、低温水分开冷却，低温水冷却两个中冷器、机油冷却器，高温水冷却气缸体与气缸盖，高温水出水温度控制在75～95℃，机油温度控制在80～110℃较适宜。该***中，水泵及风扇、散热器、机油冷却器是冷却***的主要部件。发动机运行时，由曲轴正时齿轮通过左右惰齿轮分别驱动高低温水泵，带动水泵叶轮转动，冷却液在水泵离心力作用下产生一定的压力，从水泵出口处流出。高温水泵压出的冷却液进入气缸体、气缸盖的冷却水套，冷却液 在冷却气缸体、气缸盖后至出水总管，经节温器后流入散热器。节温器装在出水管端部，节温器自动控制温度功能，当冷却液温度大于75℃时，节温器开启，当冷却液温度大于85℃时，节温器全开，此时冷却液全部进入散热器，再流回至水泵。若冷却液温度小于75℃，无需经散热器散热冷却而直接流至水泵重新走冷却循环。低温水泵则冷却两个中冷器与机油冷却器，然后回到散热器进行散热。这种高温和低温部件分类冷却，可降低进气温度和机油温度，同时减少热能损失，发动机能耗低。
综上，本实施例的V型多缸柴油机的机油供给***，通过设置油底壳1、预供油泵7、机油泵8、机油滤清器2和机油冷却器12，机油冷却器12单独由低温水循环回路来冷却，减少热能损失，发动机能耗低。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由权利要求书及其等同形式所限定。
