Science

In an adiabatic diesel engine expansion, incomplete combustion increases when which outcome?

A)Reduced exhaust energy output
B)Increased cylinder head erosion
C)Early fuel component condensation
D)Uncontrolled chain-branching reaction

💡 Explanation

Early fuel condensation inhibits complete vaporization, hence reducing local oxygen concentration, because the reduced temperature inhibits maintaining gas phase combustion. Therefore, power output decreases, rather than enhanced power as higher temperature would yield.
