柴油机的好~~以坏
柴油车优点:经济,发动机工作原理简单,扭距大 缺点:噪音大,不环保,功率小 汽油车优点:运行平稳,功率大 缺点:发动机结果复杂,维修贵 当然,这里比较的柴油车,汽油车差不多排量的前提下
关于柴油机。
柴油机的特点：功率高，经济性能良好，功率范围广，尺寸小重量轻，机动性较好，可靠性高， 寿命长，维修方便。
具有机身振动、轴系扭转振动和噪声，某些部件的工作条件恶劣，承受高温高压并具有冲击性负荷的缺点。
柴油发动机简称柴油机，是燃烧柴油来获取能量释放的发动机。
它由德国发明家鲁道夫·狄塞尔于1892年发明，为了纪念这位发明家，柴油用他的姓表示，而柴油发动机也称为狄塞尔发动机。
柴油发动机的工作过程与汽油发动机有许多相同的地方，每个工作循环经历进气、压缩、做功、排气四个行程。
但由于柴油机用的燃料是柴油，其粘度比汽油大，不易蒸发，其自燃温度却较汽油低，因此可燃混合气的形成及点火方式都与汽油机不同。
不同之处主要是柴油发动机气缸中的混合气是压燃不是点燃。
希望我的回答能够对你有所帮助。
关于柴油机的问题
柴油机的电启动或手摇启动，就是第一次压缩动力来源，启动时的转动能力被飞轮储存，在第一次减压器关闭时，这个动量引发第一次压燃，爆发推动活塞运动，带动曲轴转动，继续给飞轮储能，引发下一次爆发，这样就连续工作了。
活塞对着压有几个问题不好解决，第一：曲轴的布置不方便，无法把活塞运动转换为旋转动量。
第二，进排气不好布置，第三活塞相对运动因为阻力不完全一样，最后会失调
380的柴油机是多少千瓦的，如果是19千瓦，直接用单缸都不就好了吗
按照计算式380的发动机马力大 至于380的柴油机是多少马力 我不太清楚 但380柴油机估计就是19KW上下的样子 单缸柴油机确实有19KW的 但三缸有三缸的优势 单缸也有单缸的长处 只是看实际情况需求了 言辞能力有限 希望你能理解这些概念
80马力的柴油机机身是否越重越好
不是说机身越重越好,这要看的用途是什么,如果是在汽车上使用,为了省油,则越轻越好,如果是用在拖拉机上,因为柴油机是作为车架承受力的一部分,所以刚度必须要好.不管是轻是重柴油机的机体都必须在满足刚度的情况才能保证柴油机的可靠运行,能保证可靠性运行的情况下应该是尽可能轻.
请高手帮我翻译关于柴油机的摘要
Please help me master the summary translation on Diesel Reward points: 30 - from the end of the issue there two days 7 hours More help me translate part also, I would like to thank the. Reads as follows: In this paper, an enterprise in Jiangsu YZ4DE diesel engine for specific targets, systematically explore the finite element method in the structural design of the internal combustion engine application, the body of the aircraft conducted a comprehensive portfolio of in-depth finite element calculation and analysis, involving strength, stiffness, contacts, and thermal stress, thermal deformation, and many other issues ; a total of two conditions: Preload working conditions and working conditions (No. 2 cylinder outbreak); proposed deformation of the cylinder sets of evaluation indicators, mainly inspected the cylinder gasket sealing performance. In this paper, the finite element analysis technology to promote China's internal combustion engine in the structural design of practical applications will play a role in promoting. The main contents and main conclusions are as follows: 1. The first to use PRO \\\/ E software components establishment of the body (body, cylinder head, cylinder pad, cylinder liner, the main bearing caps, Flywheel carcasses, gear Connection Board Room, Shell pump, oil pan, about mounting frame, rear axle oil blocks, etc.) 3D solid model; Then use Hypermesh software division finite element mesh to ensure a good grid quality, and better coordination of the grid between quantity and accuracy of contradictions; Finally using ANSYS software components of a body finite element analysis. 2. Preload condition, the cylinder head bolt-hole depth of deformation of the cylinder sets a great impact on the proper cylinder head bolt hole depth Shen cylinder liner to reduce the deformation. Casting on the cylinder body tube eccentric, cylinder head bolt tightening torque, and other deformation of the cylinder liner influence is not very great. 3. Working Conditions, No. 2 cylinder (the outbreak of cylinder), the cylinder sets of radial a surplus deformation of the cylinder sets a great impact on the cylinder liner reduced radial a surplus amount to reduce the deformation of the cylinder sets, the top surface of the body decreases roughness, but it will increase the body on the plane cylinder only mouth the roughness ; Preload reduced cylinder head bolt deformation of the cylinder liner little effect, the body can reduce the top surface roughness and cylinder body on the plane I ended roughness; Shen appropriate reduced cylinder head bolt hole deep can reduce the deformation of the cylinder sets, but will cause the body and the top surface roughness on the cylinder body only I roughness increases Plane . 4. Working Conditions, high-pressure cylinder pad can be enclosed gas and lubricants, but the cooling water sealing performance poor putters in the back room near the body may have leakages. 5. Work condition, the cylinder head bolts column 2,3,4 there is a big y direction of tensile stress, the main bearing canceled with the existence of large z direction tensile stress, there is a big addition found no tensile stress areas.
