Positive Displacement flow meters are the only flow measuring instrument that can directly measure the volume of liquid passing though the flow meter.

Generally speaking, the bigger the displacement, the more volume of air and fuel a piston can move during the combustion process. This customarily means more horsepower and torque.

It is amazing that two engines that have the exact same displacement volume — as well as the same 10.5:1 compression ratio — but can be nearly 200 horsepower apart in peak performance.

Improvements in engine combustion depend on a thorough understanding of the actual in-cylinder flows. This study is thought to be the first fully three-dimensional (3-D) LDV measurement effort that ...

This does not mean that the engine displacement volume is 345 liters. Instead, these car owners want to show off their 5.7L Hemi V8 engine in a different way.
