|
compression stroke |
The stroke of the internal Combustion Engine where the piston moves into the cylinder, compressing this fuel-air mixture to high density, pressure and temperature. An electric spark then ignites the mixture and converts it into extremely hot burned gas. |
crank shaft |
The crank shaft turns the piston's up and down into circular motion. |
cylinder |
The core of the engine is the cylinder. The piston moves up and down inside the cylinder. This is an one cylinder-engine. Most cars have more than one cylinde (4, 6 and 8 cylinders are common). In multi-cylinder engines the cylinders usually are arranged in one of three ways: inline, V or horizontally opposed. |
|
|
exhaust stroke |
The stroke of the internal Combustion Engine where the piston moves into the cylinder and ejects the burned gas. The cylinder then begins again with fresh fuel and air. |
|
|
heat engine |
A device that converts thermal energy into work as heat flows from a hot object to a cold object. |
|
|
induction stroke |
The stroke of the internal Combustion Engine where a piston moves out of the cylinder and fuel and air enter it. |
|
|
piston |
A piston is a cylindrical piece of metal that moves up and down inside the cylinder. |
power stroke |
The stroke of the internal Combustion Engine where the piston moves out of the cylinder while the hot gas does work on it. |
|
|
spark plug |
The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. |
|
|
valves |
The intake and exhaust valves open at the proper time to let in air and fuel and to let out exhaust. Both valves are closed during compression and combustion so that the combustion chamber is sealed. |
