The Homogenous Charge Compression Ignition (HCCI) engine is positioned as a next-generation internal combustion engine and has been the focus of extensive research in recent years to develop a practical system. One reason is that this new combustion system achieves lower fuel consumption and simultaneous reductions of nitrogen oxide (NOx) and particulate matter (PM) emissions. However, the characteristics of HCCI combustion can prevent suitable engine operation owing to the rapid combustion process that occurs accompanied by a steep pressure rise when the amount of fuel injected is increased. Controlling the ignition timing is also an issue because it is substantially influenced by the chemical reactions of the fuel. This study focused on the use of a visualization and numerical analysis. The results showed that this approach can be found on amount of HCHO that isooctane affect n-heptane.
