Modelling and CNG distribution study of a Natural Gas-Diesel Dual Fuel Engine

Sammanfattning: Nowadays, environmental concerns have created the need of evolution in combustion engines for trying to give a solution to the growing problem of pollution produced by the combustion of fossil fuels. This master thesis project has been motivated by the developing of dual fuel engines with natural gas as main energy source for being an alternative to traditional combustion engines. Dual fuel is still a new technology that needs of research for a complete understanding of its operation, such as advantages and drawbacks, in order to improve it. For that reason, a CNG-diesel dual fuel engine has been modelled through computer software GT-POWER with the main objective of studying CNG distribution in the intake manifold and how this distribution affects to cylinder-to-cylinder variations.
