    Diesel engine
  2. What does a compression ignition engine have instead of spark plugs?
    an injector
  3. What does diesel create when it is burned?
    • water
    • carbon
    • heat
  4. When diesel inefficiently combusts, what is created?
    • carbon monoxide
    • soot
    • clogs engine
    • PCA/benzines
  5. What can be used to help diesel engine start in cold weather?
    • ether
    • coolant/lubricant heaters
    • battery heaters
    • glow plugs
  6. What are the strokes in a 2-stroke engine?
    • intake & compression
    • power & exhaust
  7. What are 3 types of forced air induction?
    • turbocharging
    • supercharging
    • RAM air
  8. Whats the advantage of forced induction?
    gets more air in the air/fuel mixture
  9. 3 uses of forced induction
    airplanes, hot rods, racecars
  10. What is scavenging?
    efficiently cleans out burnt air & fuel out of the cylinder by forcing it out
  11. strokes in a 4 stroke
    • intake
    • compression
    • power
    • exhaust
  12. Functions of a carbuerator?
    • mixes fuel and air
    • meters fuel
    • controls air flow
  13. how are carbuerators classified?
    • barrels
    • CFMs (size)
    • fuel type
  14. What is the Venturi?
    • where air horn bottlenecks
    • creates a vaccuum by lowering air pressure and increasing air speed
  15. What does the Choke Valve do?
    controls amount of air let into the carbuerator
  16. What does the Throttle Valve do?
    controls engine speed
  17. Types of small engine carbuerators
    • float
    • suction
    • pulsating suction
    • diaphragm
  18. physical difference of fuel injection and carbueration
    • carbueration has a carbuerator
    • fuel injection has a throttle body
  19. types of fuel injection and their injectors
