Supplier's note

1. Three Technical Breakthroughs:

   • Steel Construction: With steel, you can achieve 30% higher thermal resistance than cast iron, enabling stable operation in extreme conditions.
   • Direct Injection Design: The fuel nozzles’ precision alignment reduces emissions by 20% compared to traditional diesel systems.
   • Active Cooling (Pro Model): This system maintains optimal temperatures 15% faster than passive cooling, extending engine longevity.

2. Optimal Version Selection:

   • Base Model: Ideal for standard commercial use (e.g., trucks) where cost efficiency is prioritized.
   • Advanced Model: Suited for moderate performance upgrades (e.g., agricultural machinery) requiring enhanced cooling and fuel efficiency.
   • Pro Model: Designed for high-demand scenarios (e.g., racing or industrial engines) where extreme thermal resistance and lightweight are critical. The Pro’s 20:1 compression ratio, paired with active cooling, ensures peak power output even under prolonged stress.
