Abstract

In this report, the characteristics of the engine performance consuming the gasoline fuel and Compressed Natural Gas (CNG) fuel is measures. Using CNG as fuel to the engine, the power of the engine drops compared to gasoline fuel. The engine was modified to a dual-fuel system which can be operated either by gasoline fuel or CNG fuel. Besides that, the head of the engine is also had been modified for suitability to attach the PCC on to the head. For this case study, there are three types of PCC used to test the engine power output of each PCC. The PCC will be run using CNG fuel and each PCC output are compared to choose the best PCC among the three types of PCC tested. The engine was tested at engine speed between 1500 rpm to 4000 rpm. Therefore, the power of the engine can be studied so the performance result of PCC are compared. However, the experiment of CNG without PCC was also been tested and the result is compared with the three types of PCC. Besides using PCC for the experiment, we are also using the high pressure sensor to determine the power output and other parameters needed for the experiment. The result from the experiment done shown that with the application of the PCC, the power increased to 3.4 kW at the top performance of the engine while without PCC the power value is only 3.1 kW. The research is important as applying the CNG reduces the pollution to the environment but reducing the engine performance. The effect of those PCC are expected to increase the performance of the engine while using the CNG as it fuel.
