柴油机通过燃烧柴油进行做功，是一种应用范围非常广泛的驱动件。柴油机固定件的设计和布置形式对系统功能实现起到决定性作用，一个布置合理的柴油机系统对提升柴油机燃油经济性、使用便捷性、可检修性、外观整洁度尤其重要。为了提升柴油机的集成度，从而提升维护性和整洁性，便于柴油机布置，如图1-图4所示，本申请提供一种柴油机系统。本柴油机系统包括柴油机本体1、自由端罩壳2、输出端罩壳3和顶部罩壳4、水循环组件、润滑组件和冷却水循环组件。
其中，自由端罩壳2固定设置在柴油机本体1的前端，自由端罩壳2具有中空的第一容置腔、第二容置腔和第三容置腔，第一容置腔、第二容置腔与第三容置腔均互不连通，第二容置腔与柴油机本体1的主滑油管路连通；输出端罩壳3固定设置在柴油机本体1的输出端，输出端罩壳3上开设有冷却水流道和滑油流道，滑油流道与主滑油管路连通，冷却水流道与柴油机本体1的冷却管路连通；顶部罩壳4固定设置在柴油机本体1的顶部，顶部罩壳4开设有水流道，水流道分别与第一容置腔以及柴油机本体1上的加热管道连通；水循环组件设置在自由端罩壳2上，且与第一容置腔连通，水循环组件能够推动水在第一容置腔、柴油机本体1以及顶部罩壳4之间循环流动；润滑组件设置在自由端罩壳2上，且与第二容置腔连通，润滑组件能够从柴油机本体1的油底壳11吸油，通过第二容置腔进入到主滑油油路对柴油机本体1进行润滑；冷却水循环组件固定设置在自由端罩壳2上，且与第三容置腔连通，用于推动冷却水在第三容置腔、冷却管路以及冷却水流道中循环流动。
通过上述设置，将润滑组件、水循环组件和冷却水循环组件集成在柴油机本体1上，便于检修；而且通过自由端罩壳2、输出端罩壳3和顶部罩壳4将柴油机本体1上零散的部件和管路进行集成，从而使得柴油机系统整洁，便于布置。
例如，水循环组件包括水泵，水泵与柴油机本体1传动连接，水泵固定设置在自由端罩壳2上，且位于自由端罩壳2与柴油机本体1之间，水泵分别与第一容置腔以及水流道连通。通过柴油机驱动水泵工作，从而实现水在自由端罩壳2以及柴油机本体1之间的流动。
例如，水循环组件还包括水冷却组件，水冷却组件分别与水泵的进水口以 及水流道连通，用于对水流道中的部分水进行冷却。由于柴油机在工作中的过程中，会产生大量的热量，水循环过程中会升温，通过设置水冷却组件能够对水进行降温，降温后的水与原来的循环水混合，能够保证水的温度满足柴油发动机的需要。
例如，水冷却组件包括水冷却器21和温控分流阀，温控分流阀的进水口与水流道连通，温控分流阀的第一出口与水冷却器21连通，温控分流阀的第二出口与水泵的进水口连通，水冷却器21固定设置在自由端罩壳2背离柴油机本体1的一侧，水冷却器21与水泵的进水口连通。例如，水循环为闭式循环，水泵将水升压后，经过第一容置腔，进入柴油机机体分流到多个气缸套，在进入到缸盖12进行冷却，冷却后的水处缸盖12后，通过多个支管汇集到顶部罩壳4，然后进入到温控分流阀进行分流，分流后的水再次汇集到水泵的进水口进行循环。在此过程中对循环水进行一定的降温，从而满足发动机使用的要求。
例如，温控分流阀上设置有温度传感器。通过温度传感器可以实时采集循环水的温度，并根据循环水的温度控制温控分流阀第一出口以及第二出口的开度，从而能够精准控制通过第一出口和第二出口的水流量，通过第一出口进入到水冷却器21的循环水降温后与通过第二出口流入到水泵进水口的水汇合，能够保证水温满足柴油机的需要。通过上述设置，可以实现循环水温的精准调控。
例如，水循环组件还包括补水组件，补水组件包括膨胀水箱，膨胀水箱与水泵的进水口连通。由于在水循环的过程中，存在一定的蒸发和泄漏，在循环水的水量减少后，膨胀水箱将水补充到水循环管路中，从而保证循环水的量。
例如，润滑组件包括滑油泵和滑油过滤器22，滑油泵与柴油机本体1传动连接，滑油泵设置在自由端罩壳2上，且位于自由端罩壳2与柴油机本体1之间，滑油泵的一端与油底壳11连通，滑油泵的另一端通过滑油过滤器22与第二容置腔连通。滑油泵将润滑油从油底壳11中吸入，然后通过滑油过滤器22进行过滤，进入到第二容置腔中，进入到柴油机体中，对需要润滑的部位进行润滑。
例如，润滑组件还包括滑油冷却组件，滑油冷却组件分别与滑油泵的出口以及滑油过滤器22的入口连通，滑油冷却组件用于对润滑油进行冷却。由于润滑油对柴油机进行润滑的过程中，润滑油的温度会升高，从而导致润滑油的性能下降，通过滑油冷却组件将润滑油降温，然后，再进行过滤，能够保证润滑油的品质。
例如，滑油冷却组件包括滑油温控分流阀23和滑油冷却器24，滑油温控分流阀23的进油口与滑油泵的出油口连通，滑油温控分流阀23的第一出口与滑油过滤器22连通，滑油温控分流阀23的第二出口与滑油冷却器24连通，滑油冷却器24设置在自由端罩壳2上，滑油冷却器24与滑油过滤器22的入口连通。例如，滑油泵从油底壳11将润滑油泵入，然后到达滑油温控分流阀23，一部分润滑油通过第一出口进入到滑油过滤器22，另一部分通过第二出口进入到滑油冷却器24后回到滑油过滤器22，然后通过第二容置腔进入到机体主滑油管路，主滑油管路通过多个分支润滑主轴承座、凸轮轴承座、摇臂座、齿轮轴、活塞冷却喷嘴、增压器以及经过输出端罩壳3进入减振器等运动件里面。
例如，冷却水循环组件包括冷却水泵，冷却水泵与柴油机本体1传动连接，冷却水泵固定设置在自由端罩壳2上，且位于自由端罩壳2与柴油机本体1之间，冷却水泵分别与第三容置腔以及冷却水流道连通。通过柴油机驱动冷却水泵工作，从而实现冷却水在自由端罩壳2、柴油机本体1以及输出端罩壳3之间的流动。
例如，输出端罩壳3上固定设置有用于固定隔振器5的隔振机脚31。通过设置隔振机脚31便于固定隔振器5。输出端罩壳3不但作为能量输出端保护罩壳，同时支撑空冷器壳体以及部分进气管。输出端罩壳3同时还集成了低温水道、进气空气通道、隔振器5支撑功能等。
