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?
Mech_Engineer said: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:
Ranger Mike said: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?
Mech_Engineer said:I understand you know a great deal about how engines generate power, but piston speed IS related directly to the engine's rotational speed.
The main advantage of a many-V engine over a V-twin engine is that it has more cylinders, which allows for a smoother and more balanced power delivery. This results in a smoother ride and less vibration.
The more cylinders an engine has, the more power it can produce. This is because each cylinder contributes to the overall power output of the engine. Therefore, a many-V engine has a higher potential for power output compared to a V-twin engine.
In terms of fuel efficiency, many-V engines have an advantage over V-twin engines due to their higher power output. This means that the engine does not have to work as hard to produce the same amount of power, resulting in better fuel efficiency.
Yes, many-V engines have a higher top speed than V-twin engines. This is because they are able to produce more power, which allows for faster acceleration and a higher top speed.
One potential drawback of many-V engines is their larger size and weight compared to V-twin engines. This can make them more difficult to handle and maneuver in certain situations. Additionally, many-V engines may be more complex and require more maintenance compared to V-twin engines.
