How to Determine if the Igniter is Faulty?

To check the condition of an igniter, the basic approach is to input the corresponding signal voltage to the input terminal of the igniter and then examine the switching behavior (on/off) of the high-power transistor within the igniter under the influence of the signal voltage. If the high-power transistor can switch on and off as required under the signal voltage, the igniter is functioning properly; otherwise, it can be determined that the igniter is faulty. There are primarily three types of igniters: 1. Electronic Pulse Igniter: Due to its low power, the pulse igniter has a small ignition energy and produces a low-temperature spark. For gases with high ignition points or low-concentration mixed gases, the ignition success rate is relatively low, especially in burners with forced air. This often leads to ignition failures or explosive combustion, posing safety risks. Prolonged and non-continuous ignition attempts can easily damage oil-fueled burners. 2. Electronic High-Frequency High-Voltage Igniter: This type has high power and generates high-temperature sparks with substantial ignition energy. However, the ignition duration generally should not exceed 5 minutes to prevent overheating and damage. Additionally, these igniters are bulky and heavy, making installation and transportation difficult. 3. Coil Silicon Steel Sheet Igniter: With high power and energy, this igniter produces high-temperature sparks and can operate for about 10 minutes. Beyond this duration, it may overheat and burn out. While it is relatively compact and lightweight, domestically produced models are generally of poor quality, with imports occupying 90% of the market.
Here's how I see it: If the ignition system is truly malfunctioning, the car's reactions are quite noticeable. The most common symptom is difficulty starting—you turn the key for ages while the engine groans but refuses to come to life. Sometimes it might start, but the car feels sluggish, struggling to accelerate even with the pedal floored, and having trouble climbing small inclines. If the engine suddenly stalls while driving, especially at red lights, that's another red flag. You can also check the dashboard—if the ignition fault light is on, that yellowish warning light blinking away. Oh, and fuel consumption will sneakily increase too. When these symptoms pile up, it's basically the ignition system crying out for help. Don't tough it out when facing such issues—get it checked early for peace of mind.
