  1. Small and Large Engines By: Garrett Kurneck

  2. History People made blueprints of internal combustion engines up until around 1859 • 1862, French scientist put a patent on a 4-stroke engine, but he never built one. • 1878, Nikolaus A. Otto built the 4-stroke, the engine then became known as the Otto Cycle. • In 1878 a 2-stroke was made by Dougald Clerk, this is the same 2-stroke we use today.

  3. 1896, In the United states Henry Ford made his first automobile that worked in Detroit, Michigan.

  4. How it Works • Small engines are internal combustion engines. • An internal combustion engine takes fuel and blows it up to move pistons, to create power, and in turn make your car move.

  5. There are four strokes to car engines first is intake, second is compression, third is power stroke, fourth is outtake. • An engine is complex as in it is timed near perfect.

  6. Spark is what makes the car run it is the thing needed because you couldn’t blow up the pressurized gasoline without the spark. • Engines are timed based on their pistons, an eight cylinder is more powerful than a six cylinder because the more cylinders the more outtake from the cylinders. • When you hit the gas the pistons move faster to speed the car up, but the pistons are always moving when you start the car

  7. Current Examples • Cars, trucks, dirt bikes, push mowers, modern day trains, riding mowers, go-carts, etc.

  8. Future Many things are wrong with engines, they aren’t timed exactly perfect, or they aren’t fuel efficient meaning it makes the most out of its fuel. • Most likely they will try to make the engine more efficient. • They could make a lube for the pistons that you don’t have to change every so many miles.

  9. Summary • The internal combustion engine helps you get around every day . • Engines have cylinders which the pistons in cylinders make the car move by being connected to a crankshaft • The strokes are different per engine, and a 4-stroke is the new standard.
