Car Engine Components 101


Let’s face it, engines are intimidating. They’re big, they’re complicated, and when something goes wrong with them it seems like the whole world is against you. But the truth is that if you understand how your engine works—and how to keep it running smoothly—you’ll be able to drive more confidently and enjoyably than ever before! So get out of your head and into these fascinating components:

1. Carburetor

The carburetor is the part of your engine that mixes fuel with air. It’s what makes your car go and keeps it running smoothly. If you have mechanical experience, replacing a carburetor can be simple–but if this is your first time working on an engine, it’s best to leave this task to professionals.

To replace or repair a carburetor:

  • Take out any old gaskets and seals from around the base of the carburetor (using WD-40). Make sure there aren’t any cracks in these parts before installing new ones!
  • Replace any worn or damaged bolts with new ones of equal size; check for tightness after each step so everything stays snugly together throughout installation process –this will help prevent leaks later on down line when we start testing things out by firing up our engines again.”

2. Fuel Pump

The fuel pump is a mechanical device that pumps fuel from the fuel tank to your engine. It’s powered by your car’s engine and located inside of the gas tank, with an electrical connection to the rest of your vehicle.

The most common type of fuel pump is called a “diaphragm” design, which uses pressure from compressed air in order to move liquid through its chamber at high speeds without having any moving parts–except for when it comes time for you to refill your tank!

3. Distributor

  • Distributor

The distributor is a device that delivers a high-voltage electrical charge to the spark plugs. It has a rotor, which is spun by the engine’s crankshaft and causes electromagnetic coils to generate electricity in an alternating current (AC) fashion. This AC current is then used to ignite fuel inside your car’s cylinders when it reaches them via wires connected from each cylinder head’s coil pack assembly (also known as spark plug wires).

4. Spark Plugs

A spark plug is the device that produces a spark to ignite your fuel, which causes an explosion and sends you hurtling down the road. In order to do this, it has to be able to withstand high temperatures while conducting electricity.

All modern cars use a type of spark plug called a “coil-on-plug” design–that is, there’s actually an electromagnetic coil inside each individual plug rather than having one large coil under the hood or elsewhere on your engine block (like in older cars). This helps reduce weight and increase efficiency by making sure all of those electrons travel directly into their proper place without getting lost along the way!

Spark plugs are fairly easy to change yourself if they’re wearing out; just unscrew them from their sockets with some pliers or vice grips before replacing them with new ones from AutoZone or whatever other local auto parts store you prefer using when doing maintenance work on your vehicle (or ask someone at Autozone). You should also clean off any carbon deposits that may have built up inside each cylinder where these things go before installing new ones–this prevents wear on both old equipment as well as new parts being installed onto them!

5. Exhaust System

  • Exhaust System

The exhaust system is the part of the car that carries the exhaust gas from the engine to outside air. It consists of a pipe, which runs from your engine through your body and out to back of your car.

6. O2 Sensor

The oxygen sensor is used to monitor the air/fuel ratio. It’s also used to detect the amount of oxygen in your exhaust, which can be used to determine if there are problems with your engine.

The O2 sensor will send information back to your car’s computer so that it knows what kind of fuel mixture you need at any given time. If this sensor fails or becomes faulty, then it could cause other parts of your engine not to work properly as well–like causing a catalytic converter failure due to too much unburned fuel being emitted into the atmosphere by way of incomplete combustion caused by misfiring cylinders due to incorrect timing adjustments made by bad readings from faulty sensors (like this one!).

7. Ignition Control Module (ICM) or Coil Pack (COP)

The ignition control module (ICM) or coil pack (COP) is a computerized ignition system that is located in the engine compartment. The ICM/COP controls the firing of each spark plug and is connected to the distributor, coil and spark plug wires as well as to the battery.

Learning about your engine can help you to understand it better and be able to maintain it.

When you own a car, it’s important to know how your engine works. Knowing your engine can help you to understand it better and be able to maintain it yourself. You can learn about your engine by reading the manual or talking with a mechanic or learning online.


Now that you know about the different parts of your car engine, it’s time to start learning how it works. We hope this article has helped you understand what each part does and why it is important.
