In SI engines flame speed increases
A)with turbulence
B)with fuel-air ratio
C)both (a) and (b)
D)none of the above

Question

Quizplus · Accepted Answer

In SI engines, flame speed increases with both turbulence and fuel-air ratio. Turbulence enhances the mixing of fuel and air, leading to a more efficient combustion process, while the optimal fuel-air ratio ensures that there is enough fuel and oxygen for combustion to occur rapidly.
