Technical Specifications:

Advantages of the new electronic injection system of the 300L:

- Better acceleration response: Injection allows for more precise fuel dosing according to the engine's demand, resulting in a quicker and smoother response to acceleration.

- Engine performance optimization: It automatically adjusts the air/fuel mixture based on altitude, temperature, and driving conditions, ensuring consistent and optimal performance.

- Less Maintenance: No need to manually adjust the carburetor or deal with jets. Injection requires less maintenance once the system is well designed.

- Easier starting (even when cold): Starting is faster and more reliable in all conditions (cold, humidity, altitude) thanks to sensors that adjust the mixture in real time.

- Reduced fuel consumption

  • Injection limits fuel excess compared to the carburetor. This results in a better range.
