油喷清洁剂 fuel injector cleaner

美国佬汽车论坛里,有人常年使用,说很有效。有人从来不用,说没感觉。添加fuel injector cleaner 是个成本低,傻瓜也会干的事情。据说对提高发动机功效,解决部分启动/喘震/熄火问题有帮助。从网络随便搜了一些所谓的专业介绍,扔块砖头,看车坛各位老大都那些真金白银的意见和经验。

Gasoline vapor deposits left in fuel injector nozzles after an engine is shut down form hard varnish. Over time, it can build up and clog the injectors. Gasoline additives and detergents already mixed into the gasoline you buy help reduce this problem, but they can’t eliminate it entirely. Injectors periodically need to be cleaned. Some experts recommend cleaning the injectors every 25,000 to 30,000 miles to keep them flowing at peak efficiency.

But first, a word on prevention. In the U.S., most of those generic gas stations with names you’ve never heard of purchase their gasoline from the lest expensive source, sometimes including refiners who, to save a few pennies, may skimp on the engine-protecting detergents added to their product; name brand gasoline filling stations on the other hand are more reliable, many use their ‘special’ additive cocktail in their sales pitches. A special caution for those driving south of the border: just about the only gasoline you can purchase in Mexico, Pemex, is notorious for not only skimping on detergent but also selling dirty (and even watered-down) gasoline.

In addition to using top quality petrol, be certain to change your car’s fuel filter at least once a year.

But if you definitely feel the need to add additional injector-cleaning detergent to your gas tank, two such products that have been recommended to us are Chevron Techron and BG Industries 44K.
