A rapid optimisation tool allowing an assessment of thousands of firing orders for various configurations of multiple cylinder engines is utilised to identify a reduced list of options that can then be investigated in higher fidelity through detailed analytical tools. This provides the potential during clean-sheet engine design to minimise component geometries, reducing frictional losses. 1D thermodynamic simulation shows gains in fuel consumption that can also be realised from balancing the cylinder-tocylinder combustion performance to reduce the coefficient of variation on maximum cylinder pressure and exhaust temperature. For further gains in both clean-sheet and existing engine designs, consideration of the engine breathing was also included in the optimiser along with the mechanical considerations.
