Industrial Spark Plugs in Gas Engines

In modern energy systems—especially those relying on gas engines—ignition reliability is not just a component-level concern, but a critical factor in overall system performance. Whether in power generation, combined heat and power (CHP), or landfill gas utilization, the role of the industrial spark plug is central to maintaining stable, efficient, and long-term operation.

Common Problems in Gas Engine Operation

Gas engines operating under continuous load often encounter several ignition-related challenges:

1. Misfire Under Load

Misfires can occur due to inconsistent spark energy, electrode wear, or improper heat range. In high-load environments, even minor ignition inconsistencies can lead to:

Reduced efficiency

Increased emissions

Potential damage to engine components

2. Unstable Ignition Voltage

Fluctuations in ignition voltage can result from poor spark plug design or material degradation. This instability often leads to:

Irregular combustion cycles

Increased fuel consumption

Difficulty in maintaining optimal engine timing

3. High-Temperature Stress

Gas engines—especially those fueled by biogas or landfill gas—operate in high-temperature environments with corrosive elements. This can cause:

Electrode erosion

Insulator cracking

Shortened service life
