Since the invention of the internal combustion engine, automotive engineers, speed junkies and racecar designers have been searching for ways to boost its power. One way to add power is to build a bigger engine. But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A t...
testis) selgelt kõige väiksem "area under the curve" e. summaarne väändetootmine üle kogu pööretevahemiku. Turbo kompressoripool on tsentrifugaalkompressoriga sarnane, aga kuna turbo käitamiseks on kasutusel hoopis teine energiaallikas, on ka turbomootori boosti ja väändemomendigraafikud üpris erinevad. Madalatel pööretel napib nagu tsentrifugaalilgi boosti ja väänet, kuna turbost ei käi läbi küllalt heitgaase, et tiivikutele arvestatava boosti tekitamiseks vajalik kiirus anda. Seepärast kaotabki turbo selles testis 3000 pöörde juures ja enne seda nii topeltkruvile kui ka Rootsile ligi 180 lbft'iga. Kuid pisut peale 3000 pööret võtavad turbo kõverad hoopis erineva kuju mootor hakkab tootma piisavalt väljalaskegaase, et sünniks suletud ring gaasid ajavad turbot kiiremini ringi, mis omakorda
