What is a distributor-less ignition system?
Distributor-less: This is the newest type of ignition system and it’s beginning to see very widespread use on newer vehicles. It differs greatly from the other two types. 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 are the 3 types of ignition systems?
There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP). Early ignition systems used fully mechanical distributors to deliver the spark at the right time.
What are the different types of ignition systems?
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 system does not need a distributor?
A single-cylinder engine has only one spark plug and so needs no distributor. Ignition systems on such engines may produce a wasted spark during the exhaust stroke.
When did cars stop using distributors?
With the electronic ECUs the distribution and making and breaking were all electronically switched – meaning no more mechanical parts to wear. ECUs are generally good for the life of the car making them maintenance free. By the very late 1990’s mechanical distributors were pretty much gone from all cars.
What are the 4 components of the ignition system?
The basic components in the ignition system are a storage battery, an induction coil, a device to produce timed high-voltage discharges from the induction coil, a distributor, and a set of spark plugs.
What is the difference between a distributor and a coil pack?
Generally speaking, coil packs are much more reliable than distributors, because there are no moving parts and because they fire much less often than a distributor. Coil packs usually create a better spark, which in turn produces better combustion and horsepower in a car’s engine.
