A Distributor-Less Ignition System (DLIS) is a type of ignition system used in modern vehicles that eliminates the need for a traditional distributor. Instead of using a rotating distributor to send electrical signals to the spark plugs, DLIS uses multiple ignition coils, often one for each cylinder. This design improves efficiency and reliability by providing a more direct and precise spark. In a DLIS, the engine control unit (ECU) manages the timing and firing of the coils based on real-time data from various sensors. This allows for better performance, reduced emissions, and easier maintenance compared to older ignition systems. Overall, DLIS technology contributes to the advancement of automotive engineering.
