求翻译：在车辆的使用中，往往会出现漏油故障，它将直接影响到汽车的技术性能，导致润滑油、燃油的浪费，消耗动力，影响车容整洁，造成环境污染。? 由于漏油、机器内部润滑油减少，导致机件润滑不良、冷却不足，会引起机件早期损坏，甚至留下事故隐患。 一、常见车辆漏油的主要原因 １．产品（配件）质量、材质或工艺不佳；结构设计存在问题。 ２．装配高速不当，配合表面不清洁，衬垫破损、位移或未按操作规程规范进行安装。 ３．紧固螺母拧力不均、滑丝断扣或松旷脱落等导致工作失效。 ４．密封材料长期使用后磨损过限，老化变质、变形失效。 ５．润滑油添加过多、油面过高或加错油品。? ６．零部件（边盖类、薄壁件）接合表面挠曲变形、壳体破损，使润滑油渗出。? ７．通气塞、单向阀堵塞后，由于箱壳内外气压差的作用，往往会引起密封薄弱处漏油。?是什么意思？

Vehicles in use, leakage failure often occurs, it will directly affect the technical performance of the car, resulting in waste lubricating oil, fuel, consumes power, affecting the vehicle appearance clean and tidy, cause environmental pollution.? Due to oil spills, the inside of the machine lubricants to reduce, resulting in insufficient part poor lubrication, cooling, parts of early damage caused, or even leave a potential accident. First, the main cause of oil leakage of common vehicle 1. Products (accessories) poor quality, material or process; problems in structure design. 2. Improper Assembly high speed, with the surface is not clean, liner code for breakage, displacement or not according to the rules of installation. 3. Fastening nut screw force is uneven, broken sliding buckle or songkuang loss results in failure. 4. Sealing material after long-term use and wear limit, metamorphism, deformation and failure of ageing. 5. Lubricants add too much oil, oil level is too high or plus wrong.? 6. Parts (covers class, thin-walled parts) junction surface deflection, shell damage so lubricating oil seeps.? 7. After the plug of ventilation, trap blocking, because of the effect inside and outside the tank shell of air pressure difference, tends to seal leakage at weak oil.?
