The stable operation of industrial equipment directly depends on the quality of each component of the ignition system. When it comes to high-power gas engines, reliability requirements increase many times. The Denso GI3-5 candle is designed specifically for such conditions, where every hour of downtime means significant financial losses.
Modern gas piston installations operate on depleted fuel mixtures at high temperatures and pressures. In such modes, conventional candles quickly fail, requiring frequent replacement and increasing operating costs. Denso's engineering solution makes it possible to significantly extend service intervals without losing ignition efficiency.
Design features and materials
The key feature of the model is the use of Double Iridium technology. Iridium is used on both the central and side electrodes, which provides exceptional resistance to erosion and high-temperature loads.
Example: When mounting on a Caterpillar G3516 engine, it is important to use a torque wrench. Understretching will cause the spark plug to overheat due to a violation of the heat sink, and overstretching may damage the thread in the cylinder head.
Compatible with engines from leading manufacturers
Versatility of application is one of the main advantages of this model. The candle is suitable for a wide range of gas engines used in the energy, oil and gas industry and industrial production.
"Each Denso candle undergoes 100% quality control and pre-firing, which guarantees stable operation from the moment of installation."
Advantages of Double Iridium technology in operation
The use of iridium on both electrodes provides a number of practical advantages that directly affect the economics of equipment operation.
Example: In a cogeneration plant running on landfill gas with a high content of impurities, standard nickel candles need to be replaced every 600-800 hours. Denso GI3-5 candles keep working for up to 2500-3000 operating hours even in such aggressive conditions.
- Extended service life: 1500-3000 operating hours, depending on fuel quality and operating mode
- Stable sparking at low ignition coil voltage
- Minimal erosion of the electrodes when working on depleted mixtures
- Hermetically sealed connection of the electrode to the insulator through a copper-glass junction
- High dielectric strength of ceramic insulator made of purified Al2O3
- Built-in resistor reduces radio interference for on-board electronics
