Which effect reduces Otto cycle engine crankshaft power?

💡 Explanation

Increased exhaust back pressure increases the Mean Effective Pressure (MEP), compressing exhaust rather than using the piston stroke for power output, because it forces the piston to do extra work ejecting exhaust. Therefore, power decreases rather than optimized combustion timing.
