Supplier's note

  1. Three Breakthroughs:

    • Material Innovation: The Pro Model’s corrosion-resistant alloy (triple industry standard) enables safe operation in harsh environments.
    • Precision Engineering: Advanced Model piston rings reduce oil consumption by 20% compared to traditional designs.
    • Durability Boost: Base Model bearings now feature 15% improved wear resistance, extending engine life.

  2. Version Selection Guide:

    • Base Model: Ideal for routine overhauls of standard-duty 4D33 engines (e.g., passenger vehicles).
    • Advanced Model: Suited for commercial vehicles (e.g., Fuso Canter) with frequent heavy loads.
    • Pro Model: Designed for industrial engines requiring extreme durability (e.g., mining or marine applications).

With the Pro Model’s 30% stronger alloy, you can achieve 40% longer service intervals in corrosive environments. With the Advanced Model’s optimized piston rings, you can reduce downtime by minimizing oil contamination.
