The basic difference between the contact point and the electronic ignition system is in the primary circuit. The primary circuit in a contact point ignition system is open and closed by contact points. In the electronic system, the primary circuit is open and closed by the electronic control unit (ECU).
What is electronic ignition?
The electronic ignition system is the type of ignition system that uses electronic circuits, usually by transistors controlled by sensors to generate electric pulses which in turn generate the better spark that can even burn the lean mixture and provide better economy and lower emission.
What is the difference between a points coil and an electronic ignition coil?
Points have a fixed dwell angle, controlled by the points gap that you set. … The upshot is if you use a points type coil with electronic ignition you are not getting the best out of the system. If you use an electronic type coil with points you will overheat it and burn the points.
What is better points or electronic ignition?
And because there is no mechanical switch, the entire system is a whole lot more rugged in adverse environmental conditions, such as mud. The bottom line is that electronic ignition systems are LIGHT YEARS better than points systems. Simply put, there is a reason why automakers ditched points as quickly as they did.
What are the two main types of ignition system and how are they different?
Currently, there are four types of ignition systems used in most cars and trucks, by order of invention: conventional breaker-point (mechanical) ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.
What are the advantages of electronic ignition?
These are some advantages of Electronic Ignition System:
- It has fewer moving parts.
- Low maintenance required.
- Less emission generates.
- Efficiency is good.
- It also increases fuel efficiency.
How many ohms should a ignition coil have?
Most ignition coils should have a primary resistance falling somewhere between 0.4 and 2 ohms; however, refer to your manufacturer’s specifications for the correct reading.
What are signs of a bad engine coil?
Signs of a Bad Ignition Coil
- Illuminated Check Engine Light. With most modern vehicles, a faulty ignition coil is enough to turn on the Check Engine Light. …
- Misfiring Engine. If an ignition coil is not working properly, your engine will likely misfire. …
- Hard Starts. …
- Worsening Gas Mileage. …
- Diminished Power. …
- Sudden Backfires.
Does electronic ignition have a coil?
In an electronic system, you still have a distributor, but the points have been replaced with a pickup coil, and there’s an electronic ignition control module. In this system, coils sit directly on top of the spark plugs (there are no spark plug wires), and the system is completely electronic.
What does electronic ignition replace?
Most vehicles built since the 1970s have an electronic ignition system, which replaced the old breaker point ignition system. This change-over made engines run smoother and more efficiently and eliminated the need for owners to replace points and condenser every few thousand miles.
How does electronic ignition work?
An electronic ignition system is a type of ignition system that works electronic circuits, usually by transistors. The transistors are controlled by sensors to generate electric pulses which then generate a high voltage spark that can burn the lean mixture and provide a better economy and lower emission.
Does electronic ignition increase horsepower?
You don’t gain HP so much as an EI allows the engine to run at the most efficient timing for the power setting. It really doesn’t matter which EI you run because they all allow the timing to advance based on MAP and RPM.
What are the 4 types of ignition system?
Currently, we recognize four types of ignition systems used in most cars and trucks: conventional breaker-point ignitions, high energy (electronic) ignitions, distributor-less (waste spark) ignition and coil-on-plug ignitions.
What are two types of ignition system?
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)
Which type of ignition system is best?
Coil-on-Plug (Direct) Ignition System
The most sophisticated of all ignitions systems, this system places an ignition coil directly on the top of each spark plug and is ideal for modern engines. All of the ignition timing is handled by the Engine Control Unit, based on input from various sensors.
