The ignition system is responsible for providing the electrical spark that combusts the air/fuel mixture inside the engine. This process is essential for the operation of a car's engine, because without ignition there would be no explosion necessary to move the piston.
The ignition system is made up of several parts, such as the ignition coil, distributor, spark plugs and spark plug wires. The ignition coil is responsible for transforming the low battery voltage into high voltage, which is necessary to generate the electric spark. The distributor is responsible for distributing this spark to each of the spark plugs, which, in turn, combust the air/fuel mixture in each of the engine's cylinders.
The spark plug wires are responsible for carrying the electrical spark from the ignition coil to the spark plugs. It is important that these cables are in good condition, because if there is a problem, such as a short circuit, the electrical spark may not reach the spark plug, causing the engine not to work properly.
In addition, it is important that the spark plugs are in good condition and are changed regularly, as they are responsible for combusting the air/fuel mixture in each of the engine cylinders. If the spark plugs are dirty or worn out, the electrical spark may not be strong enough to generate combustion, causing the engine to lose power and consume more fuel.
Finally, it is important to highlight that the ignition system is controlled by the vehicle's electronic control unit, which is responsible for sending the necessary commands so that ignition occurs at the right time. The electronic center uses several sensors, such as the crankshaft position sensor and the valve train position sensor, to determine the exact moment when the spark must be generated, thus guaranteeing the best performance and efficiency of the engine.
