Volumetric efficiency measures how well an engine breathes.
The ratio of the actual air mass drawn in per cycle to the theoretical maximum based on displacement.
Naturally aspirated engines typically achieve 80–95%.
Given actual air mass m_actual (kg), air density ρ (kg/m³), and displacement V_d (m³), compute volumetric efficiency η_v.
