description	This thesis is deal with experimental assessment of pre chamber without auxiliary fuel into single cylinder spark ignition engine fuel with compressed natural gas (CNG) fuel. Current problem by CNG fuel in spark ignition engine is lower performance compare to gasoline fuel. Therefore, the objective of this thesis was to investigate and analyse the effect of pre chamber into performance and combustion of single cylinder spark ignition compressed natural gas engine. Methodology of this study was to apply pre chamber into single cylinder engine which use compressed natural gas as fuel source. Engine was tested by using hydraulic dynamometer combine with several sensor equipment. The sensors used during the experiment are high pressure sensor, crank angle encoder, and combustion analyzer (DAQ). The experiment were conducted based on SAE International standard J1349. The result showed that the performance of the single cylinder engine when using CNG was reduced compared to gasoline fuel. However, when pre chamber was applied to an engine,there was some performance improvement only at high engine speed. In terms of combustion, this pre chamber can also reduced in cylinder pressure, rate of heat release(ROHR), and rate of pressure rise (ROPR) compared to gasoline fuel and CNG fuel wihtout using the pre chamber. In conclusion, this study concluded that the pre chamber improve the performance of CNG fuel only at high engine speed (2500 rpm) and reduced the CNG combustion performance at lower engine speed.
