Cross-plane or Flat-plane Crankshaft?
Summary
With that in mind, this blog post explains the attributes and differences of cross-plane and flat-plane crankshafts for V8 engines using Dymola software as a design, test and validation tool. This configuration can only be used on 8 and 16 cylinder engines (basically those with multiple of 8), therefore, it is the most common around the globe and widely employed in the American muscle cars world. An interesting fact is that this type of crankshaft is the choice par excellence for European supercar manufacturers such as Ferrari and McLaren due to the following points. The two previous crankshafts were modelled in Dymola with the aim of highlighting their characteristics and carrying out the respective comparison. If it is more on the racing side, the flat-plane crankshaft is one step ahead due to its compact design, reduced weight and quicker response.
