Car ignition is one of those ubiquitous technologies that we take for granted. We flip a switch, and the car starts. But how does it work? In this article, we will explore the basics of how car ignition works. We will look at the different parts of the engine, and discuss how they work together to create power. Finally, we will cover some tips on how to troubleshoot problems with your car’s ignition.
How an Ignition System Works
An automobile’s engine relies on an ignition system to start. The system uses a spark plug to create an electric current, which then ignites the fuel/air mixture in the engine.
Types of Ignition Systems
There are three basic types of car ignition systems: battery, electric, and gas.
A battery system powers the engine by using a small number of lead-acid batteries. The system is switched on by pressing a button or turning the key.
An electric system power the engine by using an electric motor. The system is switched on by plugging in the electricity to the car’s wiring.
A gas system power the engine by using a gas pedal and a carburetor. The system is switched on by pressing down on the gas pedal.
How to Test a Car’s Ignition System
If your car doesn’t start, check the battery, cables, fuses, and ignition system. The battery should be at least 12 volts and have a good charge. Check the cables for frayed or cracked insulation. Replace them if necessary. Check the fuses for blown or weak circuitry. Replace any that are blown or weak. Be sure to test all of the ignition system components while you’re at it: key switch, coil, spark plugs, distributor cap and rotor, PCM (Permanent Magnet Motor), and wires to the distributor. If one of these components is not working properly, your car won’t start.
Troubleshooting Car Ignition Problems
If you’re having trouble starting your car, it may be due to a problem with the ignition. Here are some common problems and solutions:
1. The battery is dead. If you’ve tried turning the key multiple times and the engine still won’t start, it’s likely that your battery is toast. Replace it as soon as possible.
2. There’s something blocking the sparkplug. If you’ve tried starting your car several times, but it still doesn’t work, check for things like rocks, leaves, or wire insulation blocking the sparkplug hole. If you find something obstructing the sparkplug, remove it using a tool like a screwdriver or a socket wrench.
3. Thevoltage is too low. If your car won’t start even after replacing the battery and checking for obstructions in the sparkplug hole, your voltage may be too low to ignite the fuel mixture in the engine. You can check this by jumper-starting your car with another vehicle or by connecting an electrical voltmeter between two clean terminals on your car’s battery (be sure there are no objects between these terminals). Make sure that your voltage is high enough to start your car before continuing with step 4.
