文摘
- •
Three sets of optimization calculations were conducted.
- •
It was found that optimal valve timing produced a gain in volumetric efficiency.
- •
The optimal length of the intake duct diminishes as the engine speed rises.
- •
High volumetric efficiencies can be attained by opening the exhaust valve late.
- •
DE method was capable of finding the global extremum in the defined domain.
