Question

Describe about diesel combustion

Answer 1

The combustion of diesel is divided in 3 stages

1. Ignition lag or delay period- this first phase is the duration between the occurrence of spark at the spark plug and the deviation of combustion curve from the motor curve
2. Rapid combustion phase- the second phase starts when combustion curve deviates from the motor curve and extends to the maximum pressure reached
3. After burning- third and final phase occurs between the point of maximum pressure and maximum temperature.
