Hello everyone...can someone plz tell me...in v type engines & in OPOC. engine which one is more efficient n how it is????

 

I don't know what the acronym OPOC means.

But the configuration of the cylinders has zero effect on the thermodynamic efficiency.

Its more about compactness of the engine, and balance.

 

OPOC stands for. Opposed Piston Opposed Cylinder engine

 

OPOC engines can be designed to be inherently balanced (dynamically). Some V engines can also be designed to be inherently dynamically balanced, including the V-12. Other V engine configurations may have harmonics that cannot be balanced away or require separate balance shafts. These considerations have very minimal effect on the efficiency of a properly designed engine, which is more a result of the thermodynamic cylce efficiency and the mechanical and thermal losses in the engine.
