What is a di cassette on a Saab?
The Direct Ignition cassette is a vital part to many Saabs. Visible on top of your 9-3 (98-03) and 9-5 (98-10) engine, this part houses the spark plugs and ensures the precise firing of each cylinder, day in, day out.
What is a direct ignition cassette?
The Saab Direct Ignition Cassette serves to replace the distributor cap, distributor rotor and spark plug wires found in conventional ignition systems. The system has had a history of problems with the Direct Ignition pack itself. Typically this is evidenced by misfires but can advance to a no-start or stalling.
What is direct ignition?
A Direct Ignition system has coil for each spark plug. Usually the coils are mounted directly on top of the spark plugs with no HT leads. This ignition system is so far the best of all, as it have no moving parts or high voltage HT leads or rotor, distributor and cap and so on.
Who invented direct ignition?
The first coil-based ignition system is credited to the American inventor Charles Kettering, who developed a coil ignition system for a major vehicle manufacturer around 1910/1911. For the first time, he devised an electrical system that powered the starter motor and ignition at the same time.
Is direct injection better than port injection?
Gasoline direct injection (GDI) is a more advanced version of multiport systems, where fuel is injected directly into the combustion chamber instead of the intake port. Direct injection improves combustion efficiency, increases fuel economy and lowers emissions.
What does TCI engine stand for?
A Transistor Coil Ignition (TCI) type of an Inductive Discharge Ignition (IDI) system is an electronic ignition system used in internal combustion engines. An ignition system provides a high-voltage spark in each of the engine’s cylinders to ignite the air-fuel mixture.
What does a TCI do?
TCI (Transistor Controlled Igniter) System When the transistor is ON, current passes through the primary side of the ignition coil (coil hereinafter) from the battery to store the energy.
How do I know if I need new ignition coils?
What Are the Signs of a Faulty Ignition Coil?
- Loss of Power. This is one of the first symptoms of ignition coil failure.
- Check Engine Light On.
- Poor Fuel Economy.
- Backfiring.
- Misfiring Engine.
- Hard Starts and Stalling.
- Spluttering and Coughing Sounds.
- Jerking and Vibrating.
