Volumetrische berekeningen worden daarom gebaseerd op een molair volume van 22,414 l/mol overeenkomstig de hypothese van Avogadro. ###>Assuming no compressibility effects, all gases involved in the engine intake/combustion/exhaust process can be considered to be ideal and any volumetric calculations shall therefore be based on a molar volume of 22,414 l/mol according to Avogadro’s hypothesis.
