A CNG dedicated engine one of the types in natural gas engine is assessed as the most effective mechanism for the reduction of exhaust emissions. This work described the measuring results of a CNG dedicated engine by the experiment, In this study the characteristics of the CNG engine was investigated and then measured exhaust gas by engine performance mode at maximum load condition with increasing the engine speed in the range of 1,000-2,200rpm. The exhaust emission was also measured at D-13 mode as well as AVL-8 mode.

In this study a heavy duty diesel engine was modified into a 11-liter 6-cylinder SPI CNG dedicated engine, which was tested to investigate the performance and exhaust emission under the maximum load condition as the engine speed was increased in the range of 1,000∼2,200 rpm. The exhaust emission was also measured at D-13 mode as well as AVL-8 mode.
