Summary
As a crucial part of worldwide efforts to decarbonize commercial transport and the mobile machinery and equipment sector, carbon-neutral fuels are increasingly coming into focus for heavy applications where electrification is currently not an option. In addition to diesel substitute fuels, natural gas, hydrogen, methanol and ammonia are gaining globally increasing interest. The energy conversion of these fuels is typically based on the principle of premixed combustion, which places different demands on fuel introduction, charge movement and turbulence in the combustion chamber compared to today’s highly refined diesel-like combustion. Consequently, the need to develop multi-fuel capable engine layouts concentrates to a large amount on a tailor-made cylinder head layout that can burn these different fuels efficiently and at the same time ensures a high degree of commonality with the base engine in order to minimize production and assembly costs.
