So you’ve decided to learn about car engines. Congratulations! Car engines are some of the most fascinating pieces of machinery out there, and learning how they work is a great way to improve your understanding of how the entire transportation system works. In this article, we’ll take a look at how an ignition works, and what sorts of things can go wrong with it.
How an Ignition Works
The ignition system on a car is responsible for starting the engine. The system typically consists of an engine’s crankshaft, a flywheel, a spark plugs, and an ignition coil.
When the driver presses the key in the ignition, the spark plugs start firing. This causes compression of the air/fuel mixture in the cylinders and results in a high-voltage current travelling through the coil. This current vaporizes the fuel at the plugs and sends an extremely hot spark into the air/fuel mixture near the pistons. This sets off the fireworks show known as combustion.
Over time, metal fatigue can cause a spark plug to stop firing on its own. In this case, you would need to use a tool to crank open the head of the plug and get it started again with a fresh set of electrodes.

If your car won’t start, is having trouble starting after being pushed, or just won’t turn over, there’s a good chance your battery is dead. Here’s how to fix it.
How to Change a Car Engine Battery
If your car won’t start, there’s a good chance the battery is dead. Changing a car engine battery is a common repair, and it’s easy to do. Here’s how:
1. Park the car off the street and turn off all the lights.
2. Open the hood and remove the battery cover.
3. Remove the battery and dispose of it properly.

5. Plug in the car’s electrical connectors and turn on the car.
What to Do if Your Car Won’t Start
If your car won’t start, the first thing to do is to locate the problem. This may involve checking the battery, fuel system, starter, and ignition. If none of these seem to be the issue, you may need to take your car to a mechanic.
