Detonation is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases.

What does detonation of a word mean?

detonation Add to list Share. A detonation is an explosion, usually done on purpose. ... Its root word is the Latin detonare, which means “thunder down,” and if you've ever heard a detonation you understand that phrase well.

What is detonation in an engine?

Detonation—sometimes called knock or pre-ignition—is a pinging sound that can sometimes be heard during acceleration and throttle tip-in. Unlike normal exhaust noise, detonation is a higher-pitched, raspy note that emanates from the engine compartment.

What is a detonation in English?

1 : the action or process of detonating. 2 : rapid combustion in an internal combustion engine that results in knocking.

What is detonation in a sentence?

What is detonation or knocking?

Knocking is the making sharp sounds due to uneven combustion of fuel in the cylinder of a vehicle engine. Detonation is the process of pre-ignition or auto-ignition of a fuel in an engine's combustion chamber.

What are the effects of detonation?

Detonation has negative effects throughout the engine. Light detonation may cause premature wear on bearings and bushings. Severe or prolonged detonation can cause damage to the cylinder head and pistons.

What does denotation mean in poetry?

Denotation is the objective meaning of a word. The term comes from the Latin word “denotationem,” meaning “indication.” The denotation of a word is its literal definition—its dictionary definition—and contains no emotion.

How do you control detonation?

Investigations indicate that detonation may be controlled by retarding the rate of combustion by chemicals added to the mixture, which serve to increase its specific heat and prevent excessive temperature, and by reducing the temperature of the walls of the combustion-chamber, so that the temperature of the charge ...

What is the difference between detonation and preignition?

"Pre-ignition" is an abnormal combustion event. Pre-ignition is the ignition of the air- fuel charge while the piston is still compressing the charge. ... Detonation - Detonation, as the name suggests, is an explosion of the fuel-air mixture inside the cylinder.

What is the purpose of denotation in poetry?

Using Denotation and Connotation in Poetry Writing

Denotation and connotation allow us to choose words that give our poetry greater depth and deeper meaning. Some words have multiple definitions. Most writers will default to the simplest word and most common definition.

What is denotation and when is it used?

Denotation is used when an author wants the reader to understand a word, phrase, or sentence in its literal form, without other implied, associated, or suggested meanings.

What is difference between connotation and denotation?

DENOTATION: The direct definition of the word that you find in the dictionary. CONNOTATION: The emotional suggestions of a word, that is not literal.

What are the causes of detonation?

Detonation is generally caused by excessive heat, excessive cylinder pressure, improper ignition timing, inadequate fuel octane or a combination of these. Of the previous, excessive heat is usually the culprit. As an engine is modified to generate more power, additional heat is produced.

Is detonation bad for an engine?

Because detonation interrupts that design, it robs the engine of power. Most engines can handle some minor detonation. Modern, fuel injected engines can sense a knock and adjust the Air/Fuel Ratio and Ignition Timing. However, if the detonation is not fixed, it will damage the engine.

Can detonation cause overheating?

Detonation also creates an intense amount of stress for an engine since the explosion creates a force that pushes in a direction opposite to that of the piston's compression stroke. While numerous different factors may lead to detonation, overheating tends to be a common cause.

What is knocking and detonation and its causes?

In general, detonation is the cause and knocking is the after effect. ... Knocking is the result of the rapid combustion of end gas ahead of flame front prior to normal combustion. This cause a sharp rise of pressure inside the cylinder and cause metal pinging sound known as knock.

How do you stop engine knocking?

How to prevent engine knock?
  1. Retard Ignition Timing. Once the knock sensor receives the signal that knocking has started inside the cylinder, it sends the signal to the ECU. ...
  2. High Octane Fuel. ...

  4. Low Cylinder Temperature.

What are two terms for engine knocking?

Knocking (also knock, detonation, spark knock, pinging or pinking) in spark ignition internal combustion engines occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but one or more pockets of air/fuel mixture explode ...
