Furthermore, butanol’s higher latent heat of vaporization results in further cooling charge effect in GDI engines, which increases the volumetric and thermal efficiency. The engine was operated at stoichiometric conditions where the oxygen concentration was controlled by a Heated Exhaust Gas Oxygen (HEGO) sensor. higher flame speed).
