【 摘 要 】

Effect of combustion temperature in the engine cylinder of diesel engine convert to Compressed Natural Gas (CNG) engine was presents in this study. The objective of this study was to investigate the engine cylinder combustion temperature effect of diesel engine convert to CNG engine on variation engine speed. Problem statement: The hypothesis was that the lower performance of CNG engine was caused by the effect of lower in engine cylinder temperature. Are the CNG engine is lower cylinder temperature than diesel engine? This research was conducted to investigate the cylinder temperature of CNG engine as a new engine compared to diesel engine as a baseline engine. Approach: In this study, the combustion temperature was investigated in 7 cases engine speed. The engine speeds variation start from 1000 rpm until 4000 rpm with variation in 500 rpm. The engine conversion development and combustion temperature investigation was conducted at automotive laboratory, faculty of mechanical engineering, University Malaysia Pahang, Malaysia. Results: The results of the combustion temperature in the engine cylinder in variation engine speeds showed that diesel engine convert to CNG engine effectdecrease the combustion temperature in the engine cylinder characteristics. Conclusion/Recommendations: In the low speed the conversion can be increase the combustion temperature, but the increasing engine speeds can be decrease the combustion temperature in the engine cylinder.
