← ScienceWhich outcome raises an internal combustion engine's fuel consumption?
A)Increased cylinder wall heat transfer✓
B)Optimized air-fuel mixture ratios
C)Improved exhaust gas recirculation
D)Reduced frictional losses from pistons
💡 Explanation
Higher fuel consumption results from excessive heat loss reducing the energy available for work; this increase rises because thermal conductivity causes increased cylinder wall heat transfer, rather than from optimized combustion; therefore fuel consumption negatively affects combustion efficiency.
