    Combustion Reactions Combustion Reactions Presentation Transcript

    • Combustion Reactions
    • Different Types of Chemical Reactions
      Color, smell, size, bubbles, & dissolving

    • Combustion Reaction
      is the sequence of exothermicchemical reactions between a fueland an oxidant accompanied by the production of heat and conversion of chemical species

    • Activation Energy
      The minimum amount of energy needed for a chemical reaction to take place. For some reactions this is very small misterguch.brinkster.net/vocabulary.html(info)

    • Heat
      Without sufficient heat, a fire cannot begin, and it cannot continue. That is why heat is very important in the fire triangle.

    • Stove
      reducing its volume. A gas stove is a mechanical device that increases the pressure of a gas by

    • Combustion Engine
      In an internal combustion engine, a working fluid is heated and expanded to produce power, captured in a cylinder and piston or in a turbine or similar system, and this heating and expansion is produced by burning fuel inside the expansion chamber.
      In an external combustion engine, the working fluid is heated by burning fuel, then introduced into the expansion chamber to produce power.

    • How Combustion Engines Work
      Simply, Fuel is either drawn or injected into the combustion cylinder together with air.

    • NASCAR & Street Car Engines
      All of the subsystems like coolant pumps, oil pumps, steering pumps and alternators are designed to run at sustained high speeds and temperatures.
      They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power.
      They have carburetors that can let in huge volumes of air and fuel -- no fuel injectors on these engines.
      They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either.
      The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic.

    • Nitrous Oxide
      improves performance even more.
      When you heat nitrous oxide to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power. Nitrous oxide is one of the simplest ways to provide a significant horsepower boost to any gasoline engine.

    • Joey Logano & Tony Stewart
      were both among the cars which had their engines placed on the dynomometer for testing in postrace inspections Saturday evening.  When both the 18 and 20 engines were placed on the dyno, the cars were found to have a manipulation to the throttles.  This led to an untrue horsepower reading on the dyno.
