ABSTRACT
Supercharging reciprocating engines consists in increasing the quantity of air introduced into the combustion chamber by raising air density at intake. The aim is to increase the specific power (engine power per liter), power density and also the power per cubic decimeter or kilogram of engine. In order to achieve this, prior compression is carried out before introducing the air into the combustion chamber. Among the various existing processes, volumetric supercharging is characterized by the usage of a volumetric machine (or air pump)driven mechanically by the engine the theoretic intake volume flow is proportional to the engine speed (volume-flow drawn in at constant speed).

INTRODUCTION
The principle of turbocharging for reciprocating engines is to increase the quantity of air introduced into the combustion chamber by raising the intake air density, with the aim of increasing specific power (power per liter of engine displacement) as well as power density and power density (power per cubic decimeter or kilogram of engine).
To achieve this, the air is pre-compressed before being introduced into the combustion chamber.
Among the various existing processes, volumetric supercharging is characterized by the use of a volumetric machine (or air pump) mechanically driven by the engine, whose theoretical intake volume flow is proportional to engine speed (constant intake volume flow per revolution).
