Summary

This paper discusses the growing significance of dual fuel combustion systems in engine development, exploring the range of applications from passenger cars to large engines. The focus is on concepts that run on diesel and natural gas. First, an overview is provided of the different incentives in each area of application for developing dual fuel combustion concepts. In addition to increasingly stricter emission limits, the availability of comparative-ly cheap gaseous fuels and the possibility of easily shifting between different fuels play a large role. A survey is provided of the variety of dual fuel combustion concepts (internal/external mixture formation, high pressure/low pressure gas injection, pilot injection con-cept/substitution concept). It shows applications already in series production as well as those that are already the focus of development efforts today because they are expected to play an important role in the future.
