- •
The potential of methanol on improving the engine idle performance with lean burn strategy was experimentally investigated.
- •
Methanol enables a thermal efficiency increase at lean burn conditions with its peak value of 24.7% at λ = 1.4.
- •
Methanol can accelerate the combustion speed in cylinder and enables more stable combustion.
- •
Methanol can decrease HC, CO and NOx emissions.
