All described models use a distributorless ignition system, which consists of a battery. six coils (one for each cylinder), spark plug boot, spark plugs, camshaft position sensor, crankshaft position sensor and control system unit (RSM).
On all models, the ignition phases and operating parameters of the spark plugs are controlled in the control unit. The ignition timing cannot be adjusted.
The crankshaft position sensor receives a signal that determines the engine speed and the position of the crankshaft. Based on the received pulses, the control unit monitors the phases and operating parameters of the ignition.
The camshaft position sensor operates similarly to the crankshaft sensor, but the sensor produces one pulse per camshaft rotation. The signals from this sensor do not have a significant impact on engine operation - the pulses serve as the basis for determining misfires in the PCM, as well as for synchronizing the phases of fuel equipment.
To determine detonation, the system is equipped with a special sensor, which also registers the presence of glow ignition (usually arising due to a mismatch of fuel grade). When the sensor interacts with the PCM, the ignition timing is adjusted. When detonation is detected, the control unit adjusts the phases until it disappears. The presence of knock sensors allows you to maximize the potential of spark plugs on the verge of detonation (but without its occurrence). This ensures maximum engine performance and fuel economy.
