..., the combustion chamber needs to be optimized. One important aspect of this is the coolant used, another is the calibration of the computational fluid dynamics (CFD) to the actual engine. Once the latter has been done, the potential exists to reduce the former. To ensure lowest emissions, a dry-low NOx...
