The pressure in an operating diesel engine cylinder continues to rise for a short period after the piston passes top dead center as a result of the_______________.
AI Explanation
The correct answer is A) expansion during the combustion process.
After the piston passes top dead center, the pressure in the engine cylinder continues to rise due to the expansion of the combusted fuel-air mixture. This expansion occurs as the piston is moving down the cylinder, which increases the volume and causes the pressure to rise further before it starts to decrease. The other answer choices do not accurately describe the reason for the continued pressure rise after top dead center.
