Which consequence results when excess backflash occurs within a reciprocating internal combustion engine?

A)Increased cylinder head temperatures occur✓

B)Increased oil pressure within the sump

C)Reduced engine block hydrostatic stress

D)Decreased exhaust valve thermal cycling

💡 Explanation

Excess backflash ignites the air-fuel mixture prematurely, causing uncontrolled cylinder pressure rise because the autoignition temperature has been reached. This elevates the temperature within the cylinder, therefore overheating the cylinder head, rather than affecting oil pressure or hydrostatic stress.
