Study on the Effect of Intake Air Temperature towards RCCI Mode Engine of Performance and Emission

Significant progress has been made in the field of research pertaining to combustion engines to lower emissions such as nitrogen oxide (NOx) and carbon monoxide (CO). In recent years, the relative control compression ignition (RCCI) engine has been created to minimize emissions of nitrogen oxides (NOx). This research examines the influence of the intake air temperature has on RCCI-mode engines’ performance and emissions. A modified single-cylinder diesel engine was used to investigate the effects of changing intake air temperature and Primary Reference Fuel (PRF) over a spectrum of engine loads. The result shows that a higher air intake temperature for the RCCI strategy improved the performance of the RCCI engine, especially on fuel mixtures of B0 and PRF40, without comparing to a single fuel strategy, and reduced the amount of NOx emissions in the trade-off between UHC and CO compared to a single fuel strategy. In the not-too-distant future, one of our goals is to do more research on the influence that fuel octane has on port injection rate while maintaining the same values and parameters.
