Abstract

This research has been improvements to the fuel and air mixing based on computational modelling. This research is to simulate and analyse using original injector and new injector nozzle multi holes diameter. In the injection timing 26.9, 43.7, 63.6 and 77.5 degree BBDC, the new injector with 3.0 mm diameter hole nozzle injector is the best in fuelair mixing compared to original injector, 2.5 mm, 2.0 mm, 1.5 mm and 1.0 mm diameter hole nozzle injector. The trend in fuel – air mixing from the 3.0 mm diameter nozzle hole of injector is better than other in homogeneous of fuel and air in the combustion chamber of CNG engine. Fuel injection pressure is most important aspect of the diesel engine.
