Increased intake pressure and temperature reduces ignition delay and decreases flame speed.
View Answer Explanation
The increased flame speeds make the petrol engine more sensitive to fuel-air ratio and engine cannot run on strong mixtures without knock.
Rich mixtures are used to control detonation, which further increases the specific fuel consumption of the engine.
The ignition timings and thermal load on the engine affect the knock limit of CI engine.
The ignition must be retarded at high intake pressure and temperature.
The power developed by the turbocharger is not sufficient to drive the compressor, and overcome its mechanical friction.
The loss in piston work due to the early opening of the exhaust valve is less than offset by better charging and scavenging of the engine.
