Supplier's note

  1. Turbocharged Power (4JB1T): The 4JB1T’s turbocharger triples airflow, enabling 30% higher power output than the base model. This makes it ideal for hauling heavy loads or off-road use.
  2. Material Reinforcement: The use of aluminum alloy reduces weight by 15% compared to traditional steel engines, improving fuel efficiency without compromising strength.
  3. CE Compliance: Certification ensures emissions are 20% lower than non-certified engines, meeting EU environmental standards.

Version Selection Guide:

  • Base Model (4JA1T): Best for daily pickup/truck operations requiring moderate power and cost efficiency.
  • Advanced Model (4JB1): Suitable for commercial trucks needing enhanced torque for medium payloads.
  • Pro Model (4JB1T): Recommended for heavy-duty applications (e.g., construction, long-haul transport) where peak performance and fuel efficiency are critical.

*Performance gains calculated relative to the Base Model.
