4. Thermodynamic performance
4.1 Filling and exhaust
The fourth key parameter in this article is thermodynamic performance. In general, cylinder filling is highly dependent on the local pressure in the air intake manifold during the intake phase. This pressure is a function of the spatial distance between two consecutive combustions in the same intake manifold, i.e. the firing order and the V-angle. Depending on crankshaft topology, thermodynamic performance can be significantly impacted. In order to guarantee the highest possible and most homogeneous air filling between all cylinders, multiple indicators will be presented in this section using the 16-cylinder V configuration as an example, without calling upon detailed calculations of pressure wave propagation or valve opening duration, the aim being to introduce...
