Believe it or not, cars have been around for a long time without the convenience of digital ignition. While many newer cars have this feature, there are still plenty of older models that don’t. What is digital ignition, you ask? Simply put, it’s a system that uses electronic signals to start your engine. Instead of using a spark plug, as with traditional ignition, digital systems rely on an electrical current to start your engine. 2 wire ignition coils are one type of digital ignition system. They are used in older cars that don’t have a CD player or other electronics that would need their own power source. Is your car equipped with 2 wire ignition coils? If not, this may be something you want to consider adding to your vehicle in the near future. Not only is it convenient and modern, but it can also improve safety and performance.
What is 2 Wire Ignition?
2 Wire Ignition is a type of electrical ignition system that was first used in motorcycles and then started to be used in cars. The system uses two wires instead of the more common one wire system. The two wires are connected together at the sparkplug, and the spark is created when the current from one wire passes through the other. This system is generally less reliable than the traditional system, and it can be more difficult to repair if something goes wrong.
How Does 2 Wire Ignition Work?
2 wire ignition systems are more common in older cars. They use a primary and secondary coil to create a spark. The primary coil is connected to the engine’s spark plug, and the secondary coil is connected to the distributor. When you turn the key, the voltage supplied by the battery alternates between these two coils, creating a spark.
Pros and Cons of 2 Wire Ignition
Pros of 2 wire ignition:
-Fewer parts to fail – there are only two wires involved in a typical coil, as opposed to the more complex multiple coil systems found in many modern cars.
-Less wear and tear on the engine – with fewer parts that need regular lubrication and adjustment, 2 wire ignition is usually less prone to failure or requiring major repairs.
-Fewer sparks – with just two wires firing at once, there is much less chance of sparking causing dangerous fires.
-More reliable – due to the simplicity of a two wire ignition system, it is usually more reliable than more complex systems. This means that a 2 wire ignition coil will typically last longer than one with additional features.
Cons of 2 wire ignition:
-More difficult to tune – as there are fewer points at which adjustments can be made, tuning a 2 wire ignition system can be harder than tuning a more complex system. This can result in poorer performance over time.
What Cars Have 2 Wire Ignition Coils?
Wire ignition coils are found on a variety of cars. They usually have two leads and are made out of copper. They work by creating an electrical spark that ignites the fuel in the engine.
Conclusion
Since cars have come equipped with electronic ignition systems, it can be hard to tell the difference between a car with two wire coils and one wire coil. The important thing to remember is that two wire coils provide more power and are better for higher performance engines. If you’re not sure which type of coil your car has, consult your owner’s manual or ask a mechanic.
