"Since the first engine sucked in air, intake air has been heated to some extent. Remember on cars equipped with carburetors there was a large tube that connected to the air cleaner? Well the other end of that hose was connected to a heat collector around the exhaust manifold. This is how warm air got to the carburetor.
There's two reasons we want to heat the incoming air. The first is that the atomized fuel will mix with warm air better than cold air. This was actually more important with carburetted engines rather than fuel injected engines.
The second reason is to keep the throttle chamber from freezing. Yep, that's right. I said freezing. As in ice forming inside the throttle chamber.
Anyone who lives where it gets cold in the winter has heard of "wind chill". It'll be 30° with a wind chill of 10°. As the air moves through the throttle body, the same wind chill affects the inside if the throttle body. Under certain conditions, such as high humidity, condensation will form inside the throttle body and the moving air will freeze it. This ice will keep building up until it chokes off the air supply and the engine dies.
By running hot coolant through passages in the throttle body, it keeps the throttle body warm and prevents this ice from building up.
Some early fuel injected engines did not have heated throttle bodies and ice formation was such a problem that heated throttle bodies were retro fitted at the dealerships."
Şöyle bir makale buldum, hasta olmasam tam çevirisini yapardım ama kısaca açıklayım.
1. sebebi soğuk bölgelerde boğaz kelebeğinin donmaması, motorun daha sakin çalışması ve çabuk ısınması için (başka bir makaleyle birleştirdim) :)
2. sebebi ise atomize olmuş yakıtın, soğuk havaya göre ılık havayla daha iyi karışması. Bu ise karbüratörlü araçlarda enjektörlü araçlara göre daha büyük önem taşırmış.
Aynı zamanda bu sistemin iptali dikkate alınmayacak kadar bir performans artışı sağlarmış.
O senin tatminsizligin :)
O sogutma suyu kelebekte dolasiyor cunku gelen soguk hava ile motor suyu sicakligi dusuruluyor filan mi deseydim acaba daha fantastik bu geldi aklima simdi :)
Hah ya da dur, gaz kelebegin materyali ve emme manifoldununki ayni olmadigindan farkli genlesme katsayilarina sahiptir, oradaki su temas yuzeyindeki sicakligi birbirine yakin tutmakta ve boylece farkli sicakliklarda yuzeyden olusacak sizintilar engellenmektedir. (conta yok zaten arada hehe, neyse yersen :)
Opuyorum, fazla takilma iptal et gitsin :) baktin sikinti cikartiyor takarsin geri...
