Diesel knock is the sound produced by the very rapid rate of pressure rise during the early part of the uncontrolled second phase of combustion.
Knock is less common in ____________ climates.
Detonation can be prevented by increasing the manifold pressure by reducing the throttle opening.
Detonation cannot be prevented by reducing peak cylinder pressure.
If detonation is allowed to persist under extreme conditions or over many engine cycles, engine parts can be damaged or destroyed.
Knock is a function of the fuel chosen and may be avoided by choosing a fuel with characteristics that do not give too long a delay period.
The rate of pressure rise per degree of crank angle is then so great that an audible knocking sound occurs.
____________ knock occurs when the delay period is excessively long so that there is a large amount of fuel in the cylinder for the simultaneous explosion phase.
In CI engines, abnormal combustion is not a great problem as in SI Engines.
In ____________ combustion, the flame initiated by the spark travels across the combustion chamber in a fairly uniform manner.
