The thesis deals with the 3-D CAD model of the pre-chamber ignition system as well as drawings created in the software PTC Creo for an engine which is able to burn compressed natural gas. The aim is to create a modular pre-chamber system using mass produced parts. The CAD model is used to create a 3-D CFD model in the software AVL Fire. The parametric design of the model saves a time with creating each iteration. The 3-D CFD model shows what happens inside the chamber during the cycle and where is a space for ongoing improvements of the design to increase the efficiency, decrease the fuel consumption and decrease costs.
