Description

1. Core Function

Primary Purpose: Seals the mating surface between cylinder head and engine block to prevent:

  • Combustion chamber high-pressure gas leakage
  • Oil and coolant mixing (avoid "oil-water contamination")
  • Power loss caused by cylinder pressure leakage

2. Product Structure Analysis

Layer Structure

Material/Process

Function

Main Sealing Layer

Multi-layer steel (MLS)

Withstands high-pressure deformation (200bar+ combustion pressure resistance)

Fire Ring

Laser-welded special alloy edge

Prevents combustion chamber perimeter erosion

Micro-porous Rubber Coating

High-temperature cured silicone particles

Fills microscopic imperfections in engine block surface

Alignment Dowel Holes

Precision stamped (±0.05mm tolerance)

Ensures 100% alignment with block bolt holes

3. Working Principle

The cylinder head gasket serves as a critical sealing interface between the engine block and cylinder head, engineered to:

  • Withstand extreme combustion pressures (up to 200 bar in turbocharged engines)
  • Seal multiple fluid passages (coolant jackets, oil galleries, and combustion chambers)
  • Compensate for thermal expansion (aluminum head vs. iron block differential expansion)

Key Technologies:

  • Multi-Layer Steel (MLS) Design:

    • 3-5 laser-welded stainless steel layers with elastomer coating

    • Provides spring-like resilience to maintain seal under thermal cycling

  • Fire Rings (Combustion Seals):

    • Laser-cut high-nickel alloy rings around each cylinder bore

    • Prevents burn-through from 1,500°C+ combustion temps

  • Micro-embossed Surface Coatings:

    • 100-200μm thick silicone/rubber layers on outer surfaces

    • Fills microscopic machining imperfections (Ra ≤1.6μm required)


4.Primary Applications

A. Factory Repair & Maintenance

  • Blown head gasket symptoms:

    • Coolant/oil mixing ("milkshake" in oil cap)

    • Compression loss (>15% variance between cylinders)

    • Exhaust gas bubbles in coolant reservoir

B. Performance Engine Builds

  • Required for:

    • Engine overhauls (after head/block resurfacing)

    • Turbo upgrades (higher boost pressure compatibility)

    • Forced induction conversions

C. Critical Protection Functions

Failure Mode Prevented

Consequence if Unsealed

Combustion gas leakage

Power loss, detonation damage

Coolant intrusion into oil

Bearing corrosion, sludge formation

Oil seepage into coolant

Coolant system contamination

Cylinder pressure cross-talk

Misfires, uneven combustion


5. BMW-Specific Engineering

Adaptations for B48/B58 Engines:

  • Asymmetric Bore Spacing: Compensates for cylinder deactivation hardware (B58TU)

  • Laser-Drilled Coolant Channels: Matches precision-machined head passages

  • Torque-to-Yield Bolt Compliance: Designed for BMW's 3-stage head bolt tightening sequence
