涡轮增压汽车改天然气的坏处及原因:
1、后期维修成本高,改装天然气之后近期高、气门、燃烧室和喷油嘴等位置更容易积碳,而且容易造成怠速不稳、启动困难,发动机的使用寿命比用油会更快的降低,动力也会变差。
2、空间占用问题大,改装天然气装一个气罐是肯定的,如果是轿车的话后备箱空间本就不大,在放一个气罐进去基本就没有多少剩余空间,对日常用车会造成诸多不便。单纯出厂烧油车的设计是不可能为你改气而考虑的,气罐不仅仅增加了自重,而且时间久了对车底盘稳定性也有极大的影响。
3、发动机寿命降低,磨损过快。天然气燃烧温度高,造成发动机温度过高,发动机将会 老化过快。还有天然气虽做过处理,但是其中含有少量的硫,对发动机的腐蚀很大。

扩展资料
汽车改装天然气的优点为:
1、燃烧稳定,不会产生爆震,并且冷热起动方便。
2、压缩天然气储运,减压,燃烧都在严格的密封状态下进行,不易发生泄露。另外其储气瓶经过各种特殊的破坏性试验,安全可靠。
3、压缩天然气燃烧安全,积碳少,减少气阻和爆震,有利于延长发动机各部件的使用寿命,减少维修保养次数,大幅度降低维修保养成本。
4、可减少发动机的机油消耗量。
5、使用压缩天然气与汽油相比,可大幅度降低,一氧化碳,二氧化硫,二氧化碳等的排放。并且没有苯,铅等致癌和有毒物质危害人体健康。

涡轮增压改天然气会对发动机寿命有影响:
1、从理论上来说缸内直喷涡轮增压发动机是可以改天燃气的;
2、但实际上需要改很多东西,必须对天然气进行压缩,还需要有限压阀,压力传感器,重新匹配ECU数据,以及重新布线和管路等;
3、改动太大有可能影响到发动机的质量可靠性,一些部件容易出现早期磨损等问题。而且从车辆动力方面也会有一定的损耗。建议您根据实际使用需要决定是否改装。

涡轮增压的工作原理
汽油发动机是靠汽油与空气形成的可燃混合气在缸内燃烧做功输出动力的,电喷汽油发动机输出功率和转矩的的大小取决于进入汽缸内的空气量,当发动机的运行性能已处于最佳状态时,要想提高其输出功率只有通过压缩更多的空气进入汽缸来增加可燃混合气量,从而提高燃烧做功能力,提高其输出功率。
涡轮增压器即是利用压力推动壳体里的泵轮叶轮旋转从而带动进气增压室涡轮叶轮将空气压进汽缸,从而使提高发动机输出功率的控制装置。
动力会比烧汽油小百分之十左右;但是经济了;伤车无非就是天然气的燃烧温度比 汽油高;气门更容易烧变形;但是你看出租车不都是烧气么;跑四五十万不用大修的多的是;涡轮增压就是利用废气的排放产生动力;从而加大空气进气量;当然烧气时涡轮增压器的温度也是相应的高点;其实涡轮增压设计的寿命就是十来万公里的;不正常使用也是会坏的;你参考下;有不明白的再找我就行
1、坏处是发动机过早死,好处是省油钱
2、油改汽对汽车点火系统损坏较大,并且易发生爆缸和喘振现象,汽车抖动加剧。
3、改气后燃烧有时不充分则废气压力不足导致涡轮效率降低
4、除非是出租车和一些会经常跑长途的车建议改气(注意沿途是否有加气站),私家车不建议。
