1. Engines How they work

2. A spark plug is used to ignite the fuel in an engine

3. Piston Valves Crankshaft

4. THE FUEL GOES IN SPARK IGNITES THE EXPLOSION FORCES THE PISTON DOWN Engines produce power RPM Revolutions per minute Torque The energy produced on each cycle of the engine

5. Fuel in EXHAUST OUT 4 - cycle engine

6. PISTON CONFIGURATION 4 CYLINDER 4 cylinder 6 cylinder 8 cylinder

7. BASIC ENGINE TYPES 2- STROKE 4- STROKE

8. Engine Types 2- Stroke 4- Stroke OIL & GAS MIX OIL GAS

9. 2 Stroke Engines Oil & Gas mixed 1 Gallon

10. 2 -Stroke ENGINES USED IN : Chain Saws Weed Eaters

11. 2 - Stroke Engines Oil & Gas mixed together Notice There are no valves

12. LAWN MOWERS Use the right fuel for the engine your are running LOOK AT GAS CAP 710 Fuel Type ?

13. WARNING: Never put gas only in a 2-Stroke engine. THAT WOULD BE BAD NEWS!

14. Two types of fuel GASOLINE DIESEL GAS

15. Diesel engines burn Diesel fuel Gas engines burn Gasoline for fuel

16. GASOLINE ENGINES Good for cars Easier starting DIESEL ENGINES Good for long hauls, heavy trucks & machines Difficult to start in cold weather

17. Diesel fuel will jell up during cold weather. Makes for hard starting. “Plug in heaters are used to keep the engine warm overnite …….. BLANKET

18. WHAT’S SO SPECIAL ABOUT A DIESEL ENGINE ? Runs for long periods of time More power

19. VEHICLES USING DIESEL ENGINES

20. Diesel Bus

21. V-8 DIESEL ENGINE

22. DIESEL TRAIN

23. HEAVY EQUIPMENT

24. Low octane High octane Economy carsHigh horsepower Gasoline Cars

25. Octane describes the burn rate of the fuel The higher the octane, the smoother the fuel will burn, however it will cost more. 87 Octane91 Octane89 Octane Econo Fuel octane ratings

26. Nascar engines run on 117 high octane gas Known as racing fuel

27. Nitro- methane Extremely HIGH OCTANE

28. Dragster Nitro-fuel BURNING FUEL

29. Ethanol: Made from corn Methanol: Made from wood

30. Indy-Cars Use ethanol- fuel made from corn

31. Indiana Corn

32. One bushel of corn will make 3 gallons of ethanol fuel

33. It will take 60 bushels of corn for an Indy-Car to go 500 miles.

34. One semi will hold 1,000 bushels of corn

35. Ethanol E 10 10 % ethanol 90 % gas E 85 85 % ethanol 15 % gas

36. 85 % Alcohol

37. Will burn all mixtures of gas and alcohol On board computer monitors the type of fuel being used ….. ECM

38. ½ Gas ½ Electric

39. Bio - Fuels Using grain like corn and soybeans or vegetable oils mixed with diesel fuel

40. Fuel cells Convert hydrogen gas to electricity

41. McLaren P 1.. Speed 240 MPH Made in England … basic production

42. Supercar

43. Economy High performance
