The main manifestation of insufficient ignition coil energy

The main manifestation of insufficient ignition coil energy ‌
‌ engine starting difficulty ‌ : Insufficient ignition coil energy will cause the engine to be difficult to start, and it may take several attempts to succeed.
‌ weakened power ‌ : the vehicle's acceleration and climbing ability is reduced, and it feels that the power is insufficient during driving.
‌ increased fuel consumption ‌ : Increased fuel consumption due to inadequate combustion.
‌ jitter and idling instability ‌ : the engine jitter obviously at idle, and may also jitter during driving.
‌ stalling ‌ : In extreme cases, insufficient ignition coil energy may cause the engine to suddenly stall.
The specific cause of insufficient ignition coil energy
‌ winding short circuit ‌ : lead to voltage reduction, spark plug electrode too fast black (carbon deposit).
‌ Open circuit or ground fault ‌ : prevents the generation of high voltage, resulting in failure to ignite.
‌ surface discharge ‌ : discharge caused by dirt or moisture on the surface of the coil.
‌ insulation aging ‌ : Insulation aging caused by frequent ignition under high temperature or heavy load conditions, affecting the voltage output.

CNC ignition

In modern high-speed gasoline engines, ignition systems controlled by microprocessors, also known as digital electronic control ignition systems, have been adopted. This ignition system consists of three parts: a microcomputer (computer), various sensors, and ignition actuators.
In fact, in modern engines, both gasoline injection and ignition subsystems are controlled by the same ECU and share a set of sensors. Sensors are basically the same as those in electronic gasoline injection systems, such as crankshaft position sensors, camshaft position sensors, throttle position sensors, intake manifold pressure sensors, detonation sensors, etc. The deflagration sensor is a very important sensor for electronic ignition, especially for engines that use exhaust gas turbocharging devices. It can monitor whether the engine has deflagration and the degree of deflagration, and serve as a feedback signal to enable ECU commands to achieve ignition advance, so that the engine will not deflagrate and can achieve high combustion efficiency.
The digital electronic control ignition system (ESA) is divided into two types according to its structure: distributor type and distributor free type (DLI). The distributor type electronic control ignition system only uses one ignition coil to generate high voltage electricity, and then the distributor ignites the spark plugs of each cylinder in sequence according to the ignition sequence. Due to the fact that the on/off operation of the primary coil of the ignition coil is undertaken by the electronic ignition circuit, the circuit breaker device has been removed from the distributor and only serves the function of high-voltage power distribution.
