Abstract
The compressed natural gas (CNG) is the alternative fuel was used in this project for the modified diesel engine convert to CNG engine. The improvement was giving more advantage in emission but it was lowering the performance of the engine. This project is concentrates to improve the air-fuel mixing in the combustion chamber. The modification is focused on the intake valve part to the new design with added fin. This is to produce the swirl to the flow of the fuel mixture which entering into the combustion chamber and produce the turbulent that will increase the combustion ability. The mix between the fuel and clean air completely could increase efficiency from the burning for the reduce of emissions. The perfect mix was influenced by the swirl air flow into intake flow. The addition of fins on intake valve is expected to be able to increase velocity and the value of the massflow, hence produced more swirl air flow enter into combution chamber. The configuration of the dimension from fins also could become the stage factor from swirl.Because of that the analysis of the form is expected to be able to become a solution to get the form of fins that could give more swirl air flow.This Final Project is discussed concerning the analysis of the problem above through pemodelan use the simulation of the computer by software SolidWork. The use of this SolidWork simulation is very exact because of planning still in the stage conceptual design, so as if being carried out modelling physical, will need the big cost and relative time for quite a long time.
