← ScienceWhich outcome raises combustion engine cylinder temperatures by adiabatic compression?
A)Increased preignition knocking risk✓
B)Decreased charge air density
C)Enhanced fuel-air mixing rates
D)Lower exhaust gas temperatures
💡 Explanation
Increasing pressures cause increased preignition knocking risk, because adiabatic compression involves rapid volume reduction, increasing temperature through the Ideal Gas Law. This temperature rise leads to preignition, therefore cylinder knocking risk is increased rather than improved mixing or exhaust conditions.
