Natural Gas

Today, natural gas engines already show a great potential for minimizing CO2 emissions due to the positive H/C ratio of natural gas. The adaptation of mixture formation and combustion to natural gas as a fuel in order to obtain highest efficiency levels represents an important scope of work at the FKFS.

Additional improvements to today's natural gas engines are possible using new combustion processes adapted to the fuel. As a result, internal mixture formation used to avoid gas filling losses for intake manifold injection is one option. Furthermore, designing a jet-formed process provides the possibility for further increases in efficiency levels using an unrestricted partial load.
