Hey guys,
I am giving a short presentation on turbochargers for one of my classes, and I got all of the basics down of how it works but I still have some lingering questions
1. Nowadays you turbocharge something to increase MPG, but from what I understand a turbocharger simply allows more air (oxygen) to enter the cylinder so you can add more fuel (this would lower MPG). I am guessing that instead of a v6 you have a turbocharged 4 cylinder, and instead of a v-8 you have a turbocharged v-6. BUT all things being equal, a N/A v-6 will have better MPG than a turbocharged v-6 So ultimately you get fuel savings by having a smaller engine with less cylinders with same power output = +++MPG?
2. What affect does turbocharging have on compression ratios?
3. What is the difference between a waste-gate and a blow off valve?
4. When they mention boost pressure does that mean the pressure of air entering the cylinder? So an increase in pressure would mean more air entering? Is this separate from the density of air entering the cylinder?
Thanks guys <3
