We mostly produce aviation high pressure vitta , they are used by motocar and autocycle , ect . especially we have solved leakage in jointing and riveting by vitta tie - in . it is safe , and we can save some oil , the life can be prolonged , too 本公司主要制造航空高压油管，用于汽车、摩托车各类机械设备油管系统总成，尤其是整体式的油管接头，解决了用焊接，铆接法所产生的难以避免的泄漏，既安全又节省了油耗,延长了使用寿命。

Analysis of experimental data indicates that there exist several following problems during the whole operation : first , the emission is serious and the density of hc and co smoke is very high at on and off period . second , there is oil dripping from the dripping vitta as a result of the fault of ignition system and combustion structure . the last , there might be accidents of disabled ignition resulted from the improper operation at the beginning 通过对样机的试验分析和研究表明，汽车空气燃油加热器在整个工作过程中，其排放存在以下三个问题：一、开机和关机两个阶段的排放问题严重，废气中hc和co的浓度值及烟度测量值都很高；二、因点火系统和燃烧结构的缺陷而导致开机后一段时间内有油滴从滴油管滴落；三、在点火过程中，会出现因操作不当而点火失效的现象。
