Combustion Reactions

  1. 1. Combustion Reactions By: Delia Arciniega Per. 7/8 Ms. Sipiera
  2. 2. What are the different types of Chemical Reactions? <ul><li>Combustion </li></ul><ul><li>Synthesis </li></ul><ul><li>Decomposition </li></ul><ul><li>Single Displacement </li></ul><ul><li>Double Displacement </li></ul><ul><li>Acid-Base </li></ul><ul><li> </li></ul>
  3. 3. What is a Combustion reaction? <ul><li>A combustion reaction is when: </li></ul><ul><li>the exothermic reaction </li></ul><ul><li>that takes place between </li></ul><ul><li>certain substances, </li></ul><ul><li>particularly organic </li></ul><ul><li>compounds and oxygen </li></ul> reactions/combustion/pictures/forestfire.jpg
  4. 4. What is the fire triangle? <ul><li>The fire triangle is basically oxygen, heat and fuel that is needed to start a fire. </li></ul><ul><li> </li></ul>
  5. 5. What is Activation energy? <ul><li>The minimum amount of energy needed for a chemical reaction to take place. </li></ul><ul><li> </li></ul>
  6. 6. Why is heat/energy necessary in the fire triangle? <ul><li>The more heat that you </li></ul><ul><li>have in your fire triangle, </li></ul><ul><li>the less oxygen you will need for the fire to ignite. </li></ul>
  7. 7. What is a Combustion engine? <ul><li> </li></ul>
  8. 8. How does a Combustion engine work? <ul><li>­The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore, a car engine is an internal combustion engine combustion takes place internally. </li></ul><ul><li> </li></ul>
  9. 9. Difference between NASCAR and street cars <ul><li>The actual engine blocks and heads are not made from the original tooling, they are custom made race engine blocks, but they do have some things in common with the original engines. They have the same cylinder bore centerlines, the same number of cylinders and the same base displacement. </li></ul><ul><li> </li></ul>
  10. 10. Cheating in NASCAR. <ul><li>BROOKLYN, Mich. —  The No. 18 and No. 20 Joe Gibbs Racing teams in the Nationwide Series will likely face big penalties after efforts to alter the results of a chassis dyno test. </li></ul><ul><li>NASCAR inspectors, preparing to do tests on horsepower numbers following Saturday's Nationwide race at Michigan International Speedway, found magnets under the gas pedals on the two Gibbs Toyotas. </li></ul><ul><li>Tony Stewart, making his last Nationwide start for the Gibbs team, finished third in the No. 20, and 18-year-old rookie Joey Logano was seventh in the No. 18. The race was won by Carl Edwards in a Ford. </li></ul><ul><li>Toyota has won 15 of 25 races this season in Nationwide, and all but one came in a Camry fielded by Gibbs. The exception was JGR driver Kyle Busch's victory at Charlotte in May in a car fielded by Braun Racing. </li></ul><ul><li>In the face of such domination, last month NASCAR ordered the Toyota Nationwide teams to use a smaller spacer to cut about 15 horsepower in their motors. </li></ul><ul><li>The incident Saturday was apparently an effort to keep the current numbers from looking too strong in the latest test. </li></ul><ul><li>&quot;In our post-race inspection — yesterday was the day we were going to chassis dyno cars — our inspectors discovered some shims that were placed on the gas pedal stop,&quot; Robin Pemberton, vice president of competition for NASCAR, said Sunday. &quot;It was magnets that were about a quarter-inch thick that prevented the accelerator from going 100 percent wide open. </li></ul><ul><li>&quot;The intention was to manipulate the numbers that we get when we get our information and data off the dyno.&quot; </li></ul><ul><li>Pemberton said NASCAR officials will meet Monday and Tuesday to determine what penalties will be handed out. </li></ul><ul><li>&quot;I anticipate that we haven't seen the end of it yet,&quot; Pemberton said when asked if the penalties were likely to be severe. &quot;We historically don't make our decisions within a 24-hour period. It takes time to get everybody in a group and talk about it.&quot; </li></ul>
  11. 11. Cheating in NASCAR cont. <ul><li>J.D Gibbs said he was thankful that it was an off-track incident that did not involve racing and added that the big — and most frustrating — question is why was it done? </li></ul><ul><li>&quot;I know they were probably frustrated from the standpoint that wanting to show that, 'Hey, we have less horsepower than ever before' and they wanted to make it look like we're handicapped even more than we actually were,&quot; Gibbs said. &quot;I understand that, but that's not an excuse. </li></ul><ul><li>&quot;For us, we kind of feel like, in the engine shop that's kind of a badge of honor. You win that engine dyno, good for you. That's kind of how we felt in the past few years and [chief engine builder] Mark Cronquist and those guys really feel like they want to win that thing. </li></ul><ul><li>&quot;The way I look at it, to come back after you've been chopped, to come back and win it again, that's awesome,&quot; Gibbs noted. &quot;That's a great story. That wasn't able to be told.&quot; </li></ul><ul><li>He said no matter what action NASCAR takes, the team will address the situation in-house. </li></ul><ul><li>&quot;[We'll] figure out exactly what happened and those that were responsible,&quot; Gibbs said. &quot;There's going to be punishment for that. That's just part of life. You can't do that.&quot; </li></ul><ul><li>In a statement released by the elder Gibbs, he echoed his son. </li></ul><ul><li>&quot;If this alleged incident proves true, it goes against everything we stand for as an organization,&quot; the former Washington Redskins coach said. &quot;We will take full responsibility and accept any penalties NASCAR levies against us.&quot; </li></ul><ul><li>Lee White, president of Toyota Racing Development, said the company is grateful that the team stepped up and took responsibility and made it clear Toyota was not involved. </li></ul><ul><li>&quot;I found out about it halfway through the day session last night, when I went over there to see what was going on,&quot; White said. &quot;I was surprised to see what was happening, and astonished and frankly incredulous. I couldn't believe it was happening because it's clearly defined in the entry forms that you don't do this sort of thing. </li></ul>,2933,405301,00.html
