Part one of term paper
I have chosen to do my physics report on the internal-combustion engine. I will mention the four-stroke cycle, the components of an engine, the ignition system, the carburetor system and how an engine works. The four-stroke cycle obviously has four strokes, which consists of the intake stroke, the compression stroke, the power stroke and th ...

... This is when the piston moves up and compresses the air/fuel mixture. The mixture is compressed from atmospheric pressure to between 70 and 125 lb/sq inch. Then the power stroke is when the spark plug releases a spark inside the cylinder igniting the compressed air/fuel mixture causing the piston to fire downward at a very high speed. And finally, the exhaust stroke. This is when the piston moves up and pushes the burnt gas through a one-way valve, which then goes back into the cylinder he ...
