Key Features

2.0L Inline-Four Petrol Engine –
At the heart of the 4B11 is a 2.0-liter displacement delivering smooth and predictable performance. This square engine configuration (equal bore and stroke) contributes to excellent balance between low-end torque and high-RPM responsiveness.

MIVEC Variable Valve Timing System –
The 4B11 features Mitsubishi’s MIVEC system, which adjusts intake valve timing to optimize airflow and combustion efficiency. This enhances both low-speed drivability and high-speed performance, while also helping to reduce emissions.

All-Aluminum Engine Block and Head –
Constructed from lightweight aluminum alloy, the 4B11 is designed to reduce overall vehicle weight and improve heat dissipation. This contributes to better efficiency and improved handling dynamics.

Chain-Driven Camshaft Timing –
A timing chain system replaces the traditional belt, increasing long-term reliability and reducing scheduled maintenance costs. It’s engineered to last the life of the engine under normal driving conditions.

Advanced Multi-Point Fuel Injection –
An electronically controlled multi-point fuel injection system ensures precise fuel delivery to each cylinder, helping maximize fuel economy and maintain smooth engine operation under varying loads.
