An hmh flame speed is obtained in diesel engine when air fuel ratio is
A. Uniform throughout the mixture
B. Chemically correct mixture
C. About 35% of rich mixture
D. About 10% of rich mixture
Answer: Option D
Solution (By Examveda Team)
An hmh flame speed is obtained in diesel engine when air fuel ratio is About 10% of rich mixture. The flame speed is the measured rate of expansion of the flame front in a combustion reaction. Whereas flame velocity is generally used for a fuel. Combustion engineers differentiate between the laminar flame speed and turbulent flame speed. Flame speed is typically measured in m/s, cm/s, etc.This Question Belongs to Mechanical Engineering >> Internal Combustion Engines (I.C. Engines)
