Cylinder


We just learned about the Engine Block of a car.

One part of the engine block is the Cylinder.

The engine has a piston that goes up and down to make the car move, and the cylinder is the place that holds the piston.

Sometimes a car will 4, 6 or 8 cylinders depending on how many pistons there are.

Engine Block


We just learned about the Coupling on a locomotive.

Let's learn a little more about how most cars work.

The biggest most important part of the car is the Engine Block, sometimes called the cylinder block under the hood.

This is a big solid piece of metal in the car.
The engine block does not move, but it has parts hooked into it that move to help make the car go.

Because the moving engine is so powerful, this block has to be made in a cast or mold.
That means they take hot liquid metal, pour it into something to hold it's shape and then let it cool.
After it is cooled the block is very strong and can hold onto other pieces that are moving very fast and pushing very hard.

Car ignition


We just learned a little about Spark Plugs.

The ignition or starter is the part of the car that you put your keys into, then turn them, and it starts the car.

When you turn your keys, the car takes electricity from the battery and sends it to the sparkplugs to make a spark.
That spark explodes the gas inside the piston and starts the engine.

Spark Plug


We just learned about a car's Muffler

Inside a car engine, when the pistons go up to push on the gas and make it ready to explode, the spark plug is the thing that lets out a little spark like a match lighting a fire, and BOOM the gas explodes and pushes the piston back down.

The spark plug gets it's electricity from the car's battery, which looks like a big square block.

Muffler


A muffler is the part of the car that helps make the engine quieter.
When the engine runs it creates smoke, or exhaust, and that exhaust goes out through the muffler and then the tailpipe.

Without the muffler the car engine would be very loud.
The word "muffle" actually means to wrap something up to make it quieter,
so just like you can cover your mouth to make sounds quieter the muffler makes a car quieter.

Pistons


We just learned about Hardware and Software.

Let's learn a little about car engines.

Inside a car's engine is something called a piston.
It is inside a small metal tube, and it moves up and down.
When it moves up, it squishes the gasoline in the tube (which comes from the gas tank) and electricity comes from the spark plug and BOOM the gas explodes.

The gas explosion pushes the piston down, and that pushing over and over again is what makes the pistons run the engine and spin the wheels.
