Dissertation note: Project paper (Bachelor of Mechanical Engineering with Automotive Engineering) -- Universiti Malaysia Pahang - 2009 Abstract: The performance of an indirect injection (ID-I) compressed natural gas engine (CNG) is highly dependent on the quality of the air fuel mixture preparation. This is particular important when operating at a stratified charge condition, where ideal mixture distribution would form a homogenous region. And this has connection with the flow of injection. The study of flow pattern for injector nozzle is very important before the process is entering the real engine. Numerical simulation was carried out to investigate the effect of fluid motion of different angle nozzle in the injector. Other than investigate the fuel pattern, this project also recommend that the single nozzle hole of injector are not suitable for get a better mixing. Computational Fluid Dynamics application software (FLUENT), was used to simulate the fluid flow motion generated by different nozzle angle of injection. The analysis only was done in non-combustion bomb which is easy to identify the better flow which comes out from injector with a different angle. This project are simulated in two dimension modeling because the result can be obtain from two dimensional modeling, not in three dimension. The entire information and analysis in this thesis are hope could provide references for the future potential researchers.

The performance of an indirect injection (ID-I) compressed natural gas engine (CNG) is highly dependent on the quality of the air fuel mixture preparation.
