Abstract:
Gas and dual fuel engines applying the Otto cycle are commercially available solutions under cutting the NOx limits. Further more, it has been demonstrated that the two stage turbo charging and variable valve timing is an attractive solution to considerably improve the tradeoff between fuel consumption and NOx emissions for diesel engines.
For gas engines, the concept can be utilized to bring the trade-off between fuel consumption and power density to a new level. The potential has been confirmed on real gas and diesel engines with excellent results. A comprehensive simulation study has been carried out in order to transfer the concept of strong Miller cycle, two-stage turbo charging and variable valve timing to dual fuel engines.
By using these engines gas burns with out any residue and clean combustion results in reduced wear of engine parts and reduced consumption of lubricating oil . These engines can run by utilizing small amount of liquid fuel.
