Difference between Contact breaker and Electronic ignitions
The main difference between contact breaker and electronic ignitions is the way that they generate the spark that is needed to ignite the fuel in the engine’s cylinder.

Contact breaker ignitions, also known as points ignitions, use a mechanical system to generate the spark. This system consists of a set of contact points that open and close to create a spark at the right time in the engine’s cycle. The contact points are triggered by a cam that is attached to the engine’s crankshaft, and the spark is generated by a coil that is connected to the contact points.

Electronic ignitions, on the other hand, use an electronic system to generate the spark. This system typically consists of a sensor that detects the position of the engine’s crankshaft, a control module that processes this information and generates a signal, and an ignition coil that produces the spark.

One advantage of electronic ignitions is that they are more accurate and reliable than contact breaker ignitions. Because they use an electronic system to generate the spark, they can produce a more consistent spark at the right time in the engine’s cycle. This can result in better engine performance and fuel efficiency.

Another advantage of electronic ignitions is that they are typically easier to maintain and adjust. Because they do not have any mechanical components like contact points, there are fewer parts that can wear out or need to be replaced.

Overall, the main difference between contact breaker and electronic ignitions is the way that they generate the spark needed to ignite the fuel in the engine’s cylinder. Electronic ignitions are more accurate and reliable, and they are typically easier to maintain and adjust.

Static Ignition versus auto advance ignitions
The main difference between static and auto advance ignitions is the way that the spark timing is controlled.

Static ignition systems, also known as fixed ignition systems, use a fixed timing setting that does not change as the engine speed increases. This means that the spark is generated at the same point in the engine’s cycle regardless of the engine speed.

Auto advance ignition systems, on the other hand, use a variable timing system that adjusts the spark timing as the engine speed increases. This means that the spark is generated earlier in the engine’s cycle at higher engine speeds, which can improve the engine’s performance and fuel efficiency.

One advantage of auto advance ignition systems is that they can provide better engine performance and fuel efficiency by optimizing the spark timing for different engine speeds. This can help the engine run more smoothly and efficiently, which can result in better overall performance.

Another advantage of auto advance ignition systems is that they are typically easier to use and adjust. Because they automatically adjust the spark timing based on the engine speed, there is no need to manually adjust the timing settings.

Overall, the main difference between static and auto advance ignition systems is the way that the spark timing is controlled. Auto advance ignition systems are able to adjust the spark timing based on the engine speed, which can improve engine performance and fuel efficiency.

What is wasted spark
A wasted spark is a type of ignition system that is used in some internal combustion engines. In a wasted spark system, the ignition coil produces a spark for each cylinder in the engine, but only one of the spark plugs fires during each engine cycle.

In a typical four-stroke engine, the spark plug only fires once every other engine cycle, during the compression stroke. In a wasted spark system, the spark plug in the cylinder that is on its compression stroke will fire, while the spark plug in the cylinder that is on its exhaust stroke will not fire. This means that the spark produced by the ignition coil in the cylinder that is on its exhaust stroke is “wasted” because it does not contribute to the engine’s operation.

Wasted spark systems are typically used in engines that have two cylinders, such as motorcycles and snowmobiles. They can also be used in four-cylinder engines, but this is less common.

One advantage of wasted spark systems is that they are relatively simple and inexpensive to implement, compared to other ignition systems. They can also provide good performance and reliability, as long as the spark plugs are in good condition and the ignition system is properly adjusted.

Overall, a wasted spark is a type of ignition system that produces a spark for each cylinder in the engine, but only one of the spark plugs fires during each engine cycle. This type of system is commonly used in engines with two cylinders, and it can provide good performance and reliability at a relatively low cost.

Can a wasted spark do any better in two stroke engines?
A wasted spark ignition system can be used in a two-stroke engine, but it may not provide any significant benefits compared to other ignition systems.

In a two-stroke engine, the spark plug only fires once per engine cycle, during the compression stroke. This means that a wasted spark system would not be able to produce a “wasted” spark, because the spark plug would fire every time the ignition coil produces a spark.

Additionally, two-stroke engines often use a different type of ignition system that is better suited to their operating characteristics. Many two-stroke engines use a CDI (capacitive discharge ignition) system, which is able to produce a strong spark at the high engine speeds that are typical of two-stroke engines.

Overall, while a wasted spark system can technically be used in a two-stroke engine, it may not provide any significant benefits compared to other ignition systems. CDI systems are often a better choice for two-stroke engines, as they are able to produce a strong spark at the high engine speeds that are typical of these engines.

Which one is better CB point or static ignition or auto advance ignition system?
For a dual cylinder, two-stroke engine, an auto advance ignition system may be the best choice.

An auto advance ignition system uses a variable timing system that adjusts the spark timing as the engine speed increases. This can provide better engine performance and fuel efficiency by optimizing the spark timing for different engine speeds. This can help the engine run more smoothly and efficiently, which can result in better overall performance.

Additionally, auto advance ignition systems are typically easier to use and adjust. Because they automatically adjust the spark timing based on the engine speed, there is no need to manually adjust the timing settings. This can make it easier to maintain and troubleshoot the ignition system.

In comparison, CB point and static ignition systems do not offer the same benefits as an auto advance ignition system. CB point systems are mechanical and can be prone to wear and failure, while static ignition systems use a fixed timing setting that does not change as the engine speed increases.

Overall, an auto advance ignition system is likely the best choice for a dual cylinder, two-stroke engine. It can provide improved engine performance and fuel efficiency, and it is typically easier to use and adjust.
