Automotive How to calculate brake power in IC engines?

AI Thread Summary
Brake power in internal combustion (IC) engines is calculated using the formula hp = [RPM * Torque (ft-lbf)]/5252. The discussion clarifies that brake horsepower (BHP) refers to the engine's output power, while some participants inquire whether the focus is on brake horsepower or braking forces from engine compression. Additionally, there is a distinction between real and theoretical engines in the context of the calculation. Understanding these nuances is essential for accurate calculations of engine performance. The conversation emphasizes the importance of clarity in terminology when discussing brake power.

Are you asking about brake horsepower, or about the braking forces from engine compression braking?
 
is this a real engine or theoretical ?
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
