The Crank shaft rotates in the oil pan and splashes Oil on to the pistons.
Both sides are lubricated in order to Reduce friction.
Basic Operaion A motor has several cavitvities called cylinders. The piston moves up and down in the cylinder Thus converting vertical movement into rotary movement. This rotary movement is transfered to The wheels through a gear box to the wheels
The fuel is mixed with air in the carburetor. The air/ fuel mixture is Then put in the cylinders. This is called the Intake Stroke
Now the explosive mixture is in the cylinder, it must be crompressed prior to combustion. The piston compresses, thie mixture. This is called the: Compression Stroke
At an exact time, the spark plug ignites the mixture. This is called the: Ignition. Stroke
The piston is forced down violently during the ignition stroke then rises again to expell the Burned gasses. This is the: Exhaust Stroke
