  • Also mention: Push rod DOHC SOHC Maybe 2 stroke not needing them
  • Interferance + non-interferance engines
  • Engine Presentation

    1. 1. I'm going to tell you about engines (that's an engine) @zeenoside facebook.com/zeenoside [email_address]
    2. 2. Types of engine <ul><li>4 Stroke </li><ul><li>Inline 4
    3. 3. V8
    4. 4. V Twin (M)
    5. 5. Parrellel twin (M) </li></ul><li>2 Stroke </li><ul><li>Normally Single Cylinder </li></ul><li>Rotary
    6. 6. Deltic </li></ul>
    7. 7. What does an engine need? <ul><li>Fuel (Diesel, Petrol, LPG, etc)
    8. 8. Air
    9. 9. Spark (Catalyst)
    10. 10. Compression </li></ul>
    11. 11. Engine Basics – Cylinders + Pistons <ul><li>Piston goes up and down inside cylinder
    12. 12. Piston is attached to crankshaft </li></ul>Piston Crown Gudgeon Pin Connecting Rod (con rod) Bearings (and con rod cap)
    13. 13. Engine Basics - Crankshaft <ul><li>Pistons attach to the crankshaft which is presented to the outside of the engine allowing the power to be used. </li></ul>
    14. 14. Engine Basics – Valves + Camshafts <ul><li>Allows fuel + air to go inside the cylinder at the right time.
    15. 15. Allows exhaust gas to escape the cylinder at the right time
    16. 16. Camshaft presses on the top of the valves in order to open and close them </li></ul>
    17. 17. Why ”4 Stoke”? <ul><li>Intake
    18. 18. Compression
    19. 19. Power
    20. 20. Exhaust </li></ul>
    21. 21. Timing – what's it do? <ul><li>Allows the valves to open at the right time for the piston
    22. 22. Methods: </li><ul><li>Timing Belt (cam belt)
    23. 23. Timing chain </li></ul></ul>
    24. 24. Fuelling <ul><li>EFI (Fuel injection) </li><ul><li>Injects fuel into intake valve based on crank position
    25. 25. Very tunable
    26. 26. Lots of sensors </li></ul><li>Carburetors (magic) </li><ul><li>Injects fuel based on amount of air being sucked in + magic
    27. 27. Uses phrases like ”diaphrams”, ”floats”, ”jets”, ”needles”
    28. 28. Very delicate </li></ul></ul>
    29. 29. Spark generation
    30. 30. The computer side of things <ul><li>The computer (ECU) needs to manage: </li><ul><li>Camshaft advance/retard (lol!!)
    31. 31. Fuelling </li><ul><li>Via MAP/MAF sensors
    32. 32. Crank Position sensor (CPS) </li></ul><li>Temperature (fan control)
    33. 33. Boost (if fitted with turbo charger or super charger)
    34. 34. ”Choke”/Cold start
    35. 35. Idle speed </li></ul></ul>
    36. 36. Other systems to consider <ul><li>Lubrication system
    37. 37. Cooling system
    38. 38. Charging system
    39. 39. Turbo/Super charging (forced induction) </li></ul>
