At constant speed, delay period is proportional to the delay angle.

Increase in compression ratio ___________ delay period.

Higher cetane number means a ___________ delay period and smoother engine operation.

The delay period depends upon the nature of the fuel mixture strength.

If the delay is too short the amount of fuel available for the simultaneous explosion is too great and the resulting pressure rise is too rapid.

The ___________ extends for about 13º, movement of the crank.

INCREASE_IN_COMPRESSION_RATIO_____________DELAY_PERIOD.?$

At constant speed, delay period is proportional to the delay angle.$

Higher cetane number means a ___________ delay period and smoother engine operation?

The delay period depends upon nature of the fuel mixture strength.

The delay period ___________ with load.

The delay period depends upon temperature and pressure in the cylinder at the time of injection.

If the delay is too short the amount of fuel available for simultaneous explosion is too great and the resulting pressure rise is too rapid.

Delay period serves a useful purpose in that it allows the fuel jet to penetrate well into the combustion space.

The time for which delay period occurs decreases with ___________ in engine speed.

The ___________ extends for about 13¬¨¬®‚Äö√†¬¥, movement of the crank.$

___________ is the time immediately following injection of the fuel during which the ignition process is being initiated and the pressure does not rise beyond the value it would have due to compression of air.
