The ECU serves as the brain of the coil-on-plug ignition system. It controls the ignition timing, firing sequence of the ignition coils and duration of sparks in real-time. Hence, ensuring optimal performance and efficiency.

Maintaining a proper spark plug gap is essential for effective timing and spark duration. The ECU ensures optimization of the combustion process in relation to the engine’s power demands.

The ECU receives input from various sensors, such as the crankshaft position sensor and camshaft position sensor, to determine the optimal timing for spark ignition.

4). Crankshaft position sensor.

The role of the crankshaft position sensor is to detect the position and rotational speed of the crankshaft.

Afterwards, the information is transferred to the ECU. When it reaches there, this information is used by the ECU to determine the precise timing of spark ignition for each cylinder.

Proper grounding is essential for the effective operation of the ignition coils. Ground connections ensure that the electrical current flows efficiently through the ignition coils, enabling consistent and reliable spark generation.

How coil on plug ignition system works.

The coil-on-plug ignition system ensures efficient combustion and optimal performance. Within this set-up each engine cylinder has a separate spark plug and coil.

The Engine Control Unit (ECU) plays a vital role in controlling the ignition process. Electrical current flows through the primary winding, generating a magnetic field around it.

This primary winding is typically located within the ignition coil. Afterwards, the ECU sends a signal to momentarily interrupt the current flow in the primary winding.

The magnetic field surrounding the primary winding collapses rapidly after interrupting the current flow. This collapse induces high voltage in the secondary winding of the ignition coil.

The high voltage generated in the secondary winding is then transferred to the spark plug via its terminal connection. Once at the spark plug, this high voltage ignites the air-fuel mixture present inside the cylinder with precise timing.

Each spark plug of the coil-on-plug ignition system, receives its own dedicated ignition coil directly mounted on top of it.

Advantages of the coil-on ignition system.

Ignition timing can either be retarded or advanced. Professionals use programing software to change the timing settings in the ECU.

4). Simplified maintenance.

When necessary, replacing individual coils or spark plugs becomes more straightforward compared to conventional systems.

Spark production in the cylinder.

The ECU continuously monitors various performance parameters when the engine is running. For example, engine speed, throttle position, and temperature.

Based on this information, it calculates when to send signals to fire each individual coil, while synchronizing with piston movement.

As soon as a signal is sent by the ECU, a high voltage charge is generated within each coil. This charge is then transferred directly to its corresponding spark plug through an insulated wire or boot.

Once at the spark plug, this high voltage charge jumps across a small gap between two electrodes at its tip, creating an electrical arc that ignites the compressed air-fuel mixture inside the cylinder.

This ignition process happens rapidly and repeatedly in each cylinder according to their firing order within the engine’s combustion cycle.

Engines can achieve more precise control over spark timing and duration compared to traditional distributor-based systems by utilizing a coil-on-plug ignition system. This results in improved fuel efficiency, better power delivery, and reduced emissions.
