车子爬坡无力，提不上速，而且一直处在刚启动时的状态，---感到这是极费油。怎么办？何原因？感谢先！！！！！！:eek!:

"车子爬坡无力，提不上速，而且一直处在刚启动时的状态，---感到这是极费油。怎么办？何原因？"

建议到车行检查一下. 如果车的动力下降很大极有可能有一或几个气缸不工作了.如都工作就做下tune up并查下排气管/muffler 是否漏气.
如是由点火不足或油汽比过浓引起的燃烧不完全就会费油.<O:p

有道理.1.高压电不上电(缺缸)2.排气管堵塞3.分火器烧了(用螺丝刀刮刮)4.白金烧了(如果有火花塞的)
5.正时皮带该换了.

平时，跑高速或平地一切正常，但是，只要已有坡度就要持续踩油门，但速度还是不超过50。谢谢前者，及来者，希望有更多意见，谢了。

.分火器烧了(用螺丝刀刮刮)4，..分火器在哪里？

离合器片的问题,需要更换了,也可能是压盘磨得太厉害了推不动离合器片导致的动力丢失,国内的说法叫丢转.要鉴别的话很简单,上坡的时候突然急加一脚油门,如果发动机转数也突然升高,可是车子不加速,就一定是这个问题.我相信你的火花塞什么的一定没问题,别瞎花钱.

理论家

1) 上坡加油门是必然的.
2) 上坡车速有多高取决于: 坡度,初始车速和推力. 如果车的马力较小,坡度较大且冲坡前的车速较低上坡途中车速低,乏力是正常现象,新车也会如此.不要说50公里,一公里的时速都可能.这不是车的问题是驾驶技巧的问题.
<O:p3)“离合器片的问题,需要更换了,也可能是压盘磨得太厉害了推不动离合器片导致的动力丢失,国内的说法叫丢转. ”首先,如果是自动车,液压传动不存在这种打滑机理. 其次, 手动车在上坡,加油的情况下打滑应发生在低速(高扭矩拖动)而不是40-50公里的中速且高扭矩打滑不会太持续,否则磨擦片早失效了.最后,传动偶合的问题不会是孤立现象,应该有其他征兆如起步加速慢及车速和机器噪音不同步等.

帖主最好先检查一遍再说

Thanks everybody again.

The slope degree I mentioned above is very small, like the slope on the mount royal, which is about 10 degree or smaller.  At that time, I drive my car on the way to the mount royal lake, the car behind me can not bear the speed, and beam to me; I tried my best to depress the gas pedal, but the speed still keep around 40--50km/h, what is wrong about my car, I am confused; My engine size is 1.6, does that mean all the cars in this engine size will run like this on the slope way?   Another day, the thing impressed me is on the cote-Neige street, which includes a lot of slope, when I drive and climb on the way, I have to depress the gas pedal all the time, and the car runs very slow at 40--50, and it took a lot of gas, and runned with the "eng eng eng" sounds, as it runs very difficult, and always like the start of the running.  

However, in the flat or plain street, everything goes well, but it needs to keep giving gas for a certain long interval.  If you are interest in the condition of my car, and want to try to solve and judge the problem, I can drive my car to your place. Thank you very much.

Need your help.  I will try to use Chinese to describ this later. sorry about that.:p

To Laogadatang:
1) Your description is clear enough. If it is more convenient for you to type English it will be okay for me.<O:p2) I do strongly suggest you to go to a garage to have a check first. I may be able to identify your car’s problem but I can not help you to fix it. The most important ting is let the one who will repair your car understand what was wrong and how to fix it. You can let two or more places to estimate the problem and price before start the job. Actually, my diagnosis may not be reliable and lack of detail. <O:p3) So far, I think that the problem is the engine loses power but I can not say what is wrong and how worse it is. If you feel that the car’s performance has a significant difference between now and before you’d better go to check it out as soon as possible.

<O:pGood luck
Thanks for your trust.
