Analysis of the Effect of Intake Valve Fin Adding of Dual Fuel Engine on the Performance-Based Experiment

- Semin, Rosli Abu Bakar, Linggar Palang Aras RFC


The modification of diesel engine into the dual-fuel engine or specifically gas - oil fuel engine has been done to solve the problem of the depletion fossil fuel oil reserves in the world. Fossil fuel oil reserves are projected to be exhausted in the next 50 years or less by prediction. The working system of the gas - oil fuel engine was injecting (gas fuel) to combustion chamber along with the air during the suction step in the intake manifold and burned with the diesel as the lighter. The gas fuel was used here is CNG (Compressed Natural Gas). But the performance of the engine when using the addition of gas fuel has decreased. The modification, like the addition of fixed fin in the air intake valve, is done to increase the swirl ratio. So, that turbulent flow of air comes in along with the gas fuel to be better. As a result, the combustion process in the combustion chamber got better. By applying a fixed fin addition into the air intake valve gas-oil fuel engine, it can increase engine performance better. The power generated by the engine with fin adding increases at maximum load. While torque of engine with fin adding increased in maximum load condition. For specific energy consumption (SEC) has been decreased impact of the fin, adding on the air intake valve.
