What are the two types of ignition systems?
Although there are many different types of ignition systems on the market today, most can be placed in one of the three groups:
- Conventional breaker-point ignition (in use since the early 1900s)
- Electronic ignition (popular since the early 1970s)
- Distributorless ignition (introduced in the mid-1980s)
How does contact point ignition work?
Contact-point ignition systems: The high voltage causes sparks that jump the gaps at the spark plugs. The ignition distributor does two jobs: First, its set of contact points act as a fast acting switch which produces a high voltage surge. Second, it distributes the voltage surge in the correct firing order.
When did they stop using points in cars?
1970s
This is just a big elaborate name for the breaker-point ignition system that most cars used up until the 1970s. A breaker-point ignition system is comprised of several key components.
What is a TPI ignition?
Transient plasma ignition (TPI) – where high-energy, non-equilibrium plasma ignites flammable mixtures – has been found to promote faster flame propagation rates through a combination of larger volume ignition kernels and the generation of active radicals that enhance flame speeds.
What is the difference between contact point and electronic ignition system?
Electronic ignition systems: Contact points systems were eventually done away with because they wear out over time. Electronics ignition systems do not use contact points, they have transistors, instead that act as an electronic switch that turns the coil primary current on and off.
What’s the difference between points and electronic ignition?
Electronic systems can be unreliable, and unlike points, they will stop working without a warning. A set of points will at least give you a clue, showing such signs as running rough, or maybe they haven’t been changed in many years.
