大功率高速柴油机一般应用于发电机站、石油化工、高速轻型船舶和舰艇等。基本为四冲程机，由于大功率高速柴油机要求有非常高的单机功率，因此，其强载度要求较一般柴油机高，对于国外先进的高速柴油机，其平均有效压力最高达3MPa，最高爆压最高达20MPa。由于大功率高速柴油机要求具有高功率、大扭矩的特点，其对几项重要关键系统的要求比较高，比如缸体总成系统、动力系统、柴油系统、冷却系统、润滑系统等。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。

具体实施方式
下面结合附图，对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
如图1至图4所示，根据本发明具体实施方式的一种V型多缸柴油机的中冷增压系统，主要应用于多缸V型柴油机，如图1和图2所示，该V型多缸柴油机包括V形气缸体100， V形气缸体100上布置有呈V形排列的两列气缸孔，V形气缸体100的两列气缸孔的缸口部位分别安装有单体气缸盖200，靠近单体气缸盖200的V形气缸体100的两侧分别设有左侧进气管和右侧进气管(图中未示出)，V形气缸体100的顶部设有左侧排气管和右侧排气管(图中未示出)。
具体地，如图3和图4所示，本实施例的中冷增压系统包括左侧中冷器11和右侧中冷器21，左侧中冷器11和右侧中冷器21分别用来安装在V形气缸体100后端上方的两侧，结合图5，图5示出左侧中冷器11的结构图，左侧中冷器11和右侧中冷器21为对称结构。左侧中冷器11和右侧中冷器21为方形壳体，方形壳体的内部具有空气流通腔体，左侧中冷器11和右侧中冷器21的内侧壁向上延伸出有空气入口法兰(参见图5，其中示出左侧中冷器11的空气入口法兰15)，左侧中冷器11和右侧中冷器21的外侧壁向前延伸出有空气出口法兰(参见图5，其中示出左侧中冷器11的空气出口法兰13)，左侧中冷器11和右侧中冷器21的空气出口法兰分别用来与左侧进气管和右侧进气管接通。另外，该中冷增压系统还包括左侧增压器12和右侧增压器22，左侧增压器12和右侧增压器22对应安装在左侧中冷器11和右侧中冷器21的上方，左侧增压器12的涡轮机由左侧排气管的废气驱动，右侧增压器22的涡轮机由右侧排气管的废气驱动，左侧增压器12的压气机的出口和左侧中冷器11的空气入口法兰接通，右侧增压器22的压气机的出口和右侧中冷器12的空气入口法兰接通，至此，外界空气可以经过两个增压器的增压后分别进入左右中冷器。当然，左侧增压器12上应该连接有左侧空气滤清器，右侧增压器22上应该连接有右侧空气滤清器(图中未示出)。
作为一种优选实施例，结合图5，作为一种具体结构的中冷器，左侧中冷器和右侧中冷器为方形壳体，方形壳体的内部为空气流通腔体，空气流通腔体周围的方形壳体内设有冷却液流道。左侧中冷器和右侧中冷器之间设有中间壳体31，中间壳体31内设有与左侧中冷器11和右侧中冷器21内部的冷却液流道连通的循环通道。为了便于冷却液的循环，在每个方形壳体的前侧设有附加壳体，中间壳体31的两侧分别与左侧中冷器11和右侧中冷器21的附加壳体的内侧端面连接在一起，进而实现两个方形壳体内的冷却液经过附加壳体汇集在中间壳体31内，中间壳体31的端面上设置进水和出水口，进水口和出水口通过水管与V型多缸柴油机的冷却液循环回路接通。有时，V型多缸柴油机采用低温水和高温水分开冷却的方式，即高温水冷却气缸体和气缸盖，低温水专门用来冷却机油冷却器和本实施例的两个中冷器，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，发动机更省油。
上述方案中，采用现有的废气涡轮增压技术，通过左右各有一套独立的增压中冷系统。发动机工作时，来自发动机排气管的废气进入增压涡轮，废气压力中的热能使涡轮转动，并使与涡轮同轴的压气机转动，压气机将空气吸入并压缩，然后通过管道进入发动机进气管，离开涡轮的已冷却和膨胀的废气由涡轮壳引向发动机排气系统并进入大气。进气经压缩后，提高了充入气缸的空气密度，在供油系统的良好配合下，使更多的燃料得以充分燃烧，提高了功率，并改善经济性。
综上，本实施例的V型多缸柴油机的中冷增压系统，通过在V形气缸体的左右两侧各设有一套独立的增压中冷系统，采用现有的废气涡轮增压技术，进气经本中冷增压系统压缩后，提高了充入气缸的空气密度，在供油系统的良好配合下，使更多的燃料得以充分燃烧，提高了功率，并改善经济性，满足大功率高速柴油机高功率、大扭矩的进气要求。
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。
