Abstract
To improve exhaust emission characteristics of gas engine by controlling heat release rate, a multi-combustion zone model was applied to a cycle simulation program. The program was examined with the results of the single combustion test.
The test results have shown to be proper for estimating the change of NOx emission when the heat release rate is changed. By inspecting with the various rates, the longer duration of high temperature in the heat release process resulted in the higher NOx emission. From the results of simulation, it has been shown to be able to improve the exhaust emission characteristics of the gas engine by controlling the heat release rate.
