本实用新型专利技术V型柴油发动机机体,采用两气缸成V型排列,并且没有将主油孔布置在机体上,而是布置在与机体配合的箱盖上,可以在V型气缸夹角内和V型气缸外侧下部布置更多的零部件,使得整体结构紧凑,外形造形美观,体积小。由于机体采用铝合金压铸件,散热片也整体压铸成形,适用于大批量生产,整体质量轻巧,外部造型美观。并且整体采用风冷降温,并且在气缸的表面设有散热片,散热片之间的间隙形成贯穿的通风槽,可以充分利用空气流动实现散热,彻底抛弃机体的水夹层结构,制造工艺简化,重量轻,成本低,没有漏水问题。由于在前端面上增加了密封孔,针对传统的密封孔排布易产生漏油的问题,将容易导致漏油的位置重点加固,达到防漏油的效果。(*该技术在2022年保护过期,可自由使用*)

V diesel engine block

The body of the utility model V diesel engine, the two cylinder V type arrangement, and there will be a main oil hole arranged on the body, but the body is arranged in and with the box cover can be arranged more parts in the V type and V type cylinder cylinder angle in the outer side of the lower part of the body, compact structure, shape beautiful shape, small volume. Due to the use of aluminum alloy die casting, heat sink is also the overall die casting, suitable for mass production, the overall quality of lightweight, beautiful exterior appearance. And the overall use of air cooling, and a heat sink is arranged on the cylinder surface, the gap between the heat sink formed through the ventilation slot, can make full use of air flow to achieve cooling, completely abandoned water interlayer structure of the body, simple manufacturing process, light weight, low cost, no problem Water Leakage. Due to the increase of sealing holes on the front end surface, the problem of oil leakage is easy to be caused by the arrangement of the traditional sealing holes.
