What is the advantage of a big V engine over a V-twin engine? Why not just use extra-large V-twin engines instead of using V-12 engines and such?
Also, power output is proportional to engine speed, and one huge v-twin engine would not be capable of very high rpms. However it is true that for very large engine applications like cruise ships, very large displacement diesel engines are utilized rather than lots of smaller ones.
Actually no. Engine power is not proportional to RPM but to piston speed:
That is because the power you can get out of an engine is proportional to the surface area of the cylinder bore (and not to the displacement, as most people think)
Forgive me but is not the displacement of one cylinder the total volume of that bore? and is not volume, the surface area of that bore?? Or did you mean the piston top surface area? Or does surface area of the cylinder bore include the combustion chamber? Would this include the volume of the cylinder head gasket?
I understand you know a great deal about how engines generate power, but piston speed IS related directly to the engine's rotational speed.
