detonates, 3rd person singular present; detonating, present participle; detonated, past tense; detonated, past participle;
  1. Explode or cause to explode
    • - two other bombs failed to detonate
    • - a trigger that can detonate nuclear weapons
  1. explode: cause to burst with a violent release of energy; "We exploded the nuclear bomb"
  2. burst and release energy as through a violent chemical or physical reaction;"the bomb detonated at noon"; "The Molotov cocktail exploded"
  3. (detonation) the act of detonating an explosive
  4. Detonation involves an supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. They are observed in both conventional solid and liquid explosives, as well as in reactive gases. ...
  5. (Detonation (band)) Detonation is a Dutch melodic death metal band, with members from the Netherlands and the United States. In recent years the band has gravitated towards a melodic death metal sound.
  6. : To explode; to blow up. Specifically, to combust supersonically via shock compression; : To cause an explosion
  7. (detonation) An explosion or sudden report made by the near-instantaneous decomposition or combustion of unstable substances as, the detonation of gun cotton. ...
  8. (detonated) To explode or cause to explode
  9. (Detonation) an exothermic chemical reaction in which the explosive decomposition of a substance forms an energy wave that propagates through the substance at supersonic speeds.  High explosives such as TNT and dynamite detonate; fireworks do not.
  10. (Detonation) The almost instantaneous release of heat energy from fuel in an engine caused by the fuel-air mixture reaching its critical pressure and temperature. It is an explosion rather than a smooth burning process. More
  11. (Detonation) A violent explosion involving high-velocity pressure waves; in a gasoline engine, the spontaneous combustion of part of the compresses charge after spark occurs. Detonation usually produces a characteristic metallic sound, or knock.
  12. (Detonation) A violent chemical reaction within a chemical compound or mechanical mixture evolving heat and pressure.  A detonation is a reaction that proceeds through the reacted material toward the un-reacted material at a supersonic velocity. ...
  13. (Detonation) The secondary ignition of the air/fuel mixture in the combustion space causing extreme pressures. Detonation is caused by low gasoline octane ratings, high combustion temperatures, improper combustion chamber shape, too-lean mixtures, etc. ...
  14. (detonation) a type of explosion of the highest rate of propagation, accompanied by a shock wave. It is often defined as a rate of propagation which exceeds the speed of sound in the same material. ...
  15. Detonation in gasoline engines is usually caused by heat or pressure resulting in an explosion of the unburnt portion of the fuel (knocking). This force is extremely destructive to engines, and may result in holes blown through the top of pistons or engine blocks. ...
  16. (Detonation) A rattling, pinging type noise, normally experienced on acceleration and under load. Left unattended engine damage can result. For more information see our Detailed Auto Topics Valve clatter, spark knock, pinging and pre-ignition. (see also spark knock, pinging and labor knock)
  17. (Detonation) Any rapid chemical reaction accompanied by noise and often heat and light, e.g., explosions.
  18. (Detonation) Explosive, uneven burning of fuel causing engine knock.
  19. (Detonation) The action of converting the chemicals in an explosive charge to gases at high pressure, by means of a self-propagating shock wave passing through the charge.
  20. (Detonation) The action of the fuel charge firing or burning too violently, almost exploding. It sometimes results in a noise called Pinging. Detonation is caused by Autoignition of the End gas i.e., that part of the charge not yet consumed in the normal flame-front reaction. ...
  21. (Detonation) The molecular breakdown of a substance brought about by shock. Initiated by detonator.
  22. (Detonation) This is an engine condition in which the usually smooth and controlled combustion process has a violent and out of sequence burst. This sudden spike in combustion can drastically increase the pressure in the cylinder but is too fast to effectively contribute to the engine's output. ...
  23. (Detonation) When the air/fuel mixture explodes out of sequence either due to poor tuning, timing, or poor fuel quality.
  24. (Detonation) is slang for “knock” – that sounds pretty slang too doesn’t it. Anyway, it means basically that the sequence of combustion in the engine, instead of being smooth and controlled keeps having violent outbursts – needs a bit of engine anger management.
  25. (Detonation) occurs when the air/fuel mixture is compressed and the temperature goes up. The more compression, the higher the temp. At some point, the fuel may spontaneously ignite prior to the spark plug firing. ...
