Special Spark Plug 12420480 (Genuine DEUTZ/MWM Part)
Part No. 12420480 is a dual iridium spark plug specially for DEUTZ MWM gas engines. It is an original genuine part for reliable ignition of natural gas, biogas and other gaseous fuels, compatible with TBG/TCG series gas engines.
1. Basic Information
- Part Number: 12420480
- Name: Gas Engine Spark Plug
- Brand: DEUTZ / MWM
- Applicable Models:
DEUTZ MWM TBG 616/620 gas engines
DEUTZ MWM TCG 2016/2020/2032 series
Suitable for industrial gas units running on natural gas, biogas, landfill gas, etc.
- Function: Ignite air-fuel mixture to ensure stable ignition, efficient combustion and low emissions.
- Matching Parts: Core component of valve train and ignition system, used together with rocker arm assembly 12420479 and cylinder head gasket 12420482.
2. Material & Manufacturing Process
- Electrode Material: Dual iridium electrodes (both central and ground electrodes). Features high melting point, excellent erosion resistance and long service life.
- Shell Material: High-strength alloy steel with good corrosion resistance and vibration resistance.
- Insulator: High-purity alumina ceramic, high temperature resistant and superior in insulation performance.
- Resistor: Built-in 5kΩ damping resistor to suppress electromagnetic interference.
- Operating Temperature: -40℃ ~ +650℃, applicable to gas engines under high explosion pressure and high temperature conditions.
- Heat Rating: 77 (high heat rating for continuous heavy-duty operation).
3. Key Dimensions (Original Standard)
- Thread Specification: M18×1.5
- Thread Length (Insertion Depth): 20.6 mm
- Hex Size: 20.8 mm
- Electrode Gap: 0.3 mm (cold condition)
- Sealing Type: Metal gasket sealing
- Unit Weight: Approx. 0.5 kg
4. Functions & Features
- Long Service Life: Dual iridium electrodes achieve a service life of 8000–10000 hours, reducing downtime and replacement frequency.
- Stable Ignition: Precise gap and concentrated spark ensure reliable ignition under low temperature and heavy load, avoiding misfire.
- Vibration Resistance: Reinforced shell and electrode structure adapt to severe vibration of industrial engines.
- Wide Compatibility: Works well with natural gas, biogas, coal bed gas and other gaseous fuels, and resists carbon deposition and coking.
- Low Interference: Built-in damping resistor protects ignition modules and electronic control systems.
5. Replacement & Compatibility
- Genuine Alternative Part No.: 12420480 (No updated replacement part)
- Equivalent Models:
BO SCH: 0242356515 / MR3DII360
DENSO: GL3-3 / GL35
BERU: 18GZ5-77-5
- Recommended Aftermarket Brands: BO SCH, DENSO, BERU. Thread specification, electrode gap, heat rating and electrode material must be fully matched.
6. Installation Instructions
- Inspection & Cleaning: Check the insulator for cracks, electrodes for erosion and oil contamination, and threads for integrity.
- Installation Torque: 70±5 Nm (cold condition). Do not over-tighten to prevent damage.
- Gap Check: Confirm the electrode gap is 0.3 mm before installation and adjust if out of tolerance.
- Sealing Check: Ensure the gasket is flat and threaded holes on cylinder head are clean to prevent air leakage.
- Replacement Cycle: Replace every 8000 operating hours or 12 months, whichever comes first. Complete set replacement is recommended.
