Tur­bocharg­ing vs. Su­per­charg­ing

HWM (Singapore) - - Learn - by Ken­nyYeo

As its name sug­gests, forced in­duc­tion is re­ally about “forc­ing” or get­ting more air into the in­take of an en­gine so that more fuel can be burnt and more power can be gen­er­ated. The two most com­mon meth­ods of do­ing so are tur­bocharg­ing and su­per­charg­ing, and we are go­ing to learn more about them to­day.


In­creas­ing the in­take of air into the en­gine is one of the ways an in­ter­nal com­bus­tion en­gine can make more power. More air means more oxy­gen, which means more fuel can be burnt, and that trans­lates to more en­ergy and power the en­gine pro­duces. There­fore, it stands to rea­son that the big­ger the dis­place­ment of the en­gine, there more power it can make. How­ever, this is not al­ways fea­si­ble or de­sired. Big­ger en­gines also mean more weight and also gen­er­ally cost more to build and de­velop. And in Sin­ga­pore, for ex­am­ple, cars with big­ger en­gines also in­cur higher taxes. Forced in­duc­tion tech­nol­ogy aims to over­come this and al­low en­gines to make more power than they other­wise could by mod­i­fy­ing and in­creas­ing their air in­take.
