- Summary:
- Stringent emission regulations and the anticipated climate change call for a paradigm shift in the design of the conventional internal combustion engines. One way to combat this problem is oxy-fuel combustion in which the emissions are mainly water vapor and carbon dioxide. Water vapor can be easily separated by condensation and carbon dioxide is then easily captured and stored. However, many technical challenges are associated with this mode of combustion. There are many challenges facing oxy-fuel combustion before it find its way to commercial production especially for internal combustion engines. One such challenge is the relatively high temperature of the oxy-fuel combustion. A solution to this problem is the recirculation of the generated CO2 to moderate the in-cylinder temperature. Therefore, careful study of the effect of recirculating the CO2 back to combustion chamber is needed before the implementation of such a concept. In this present study the performance of an oxy-fuel HCCI engine with recirculated carbon dioxide to moderate the in-cylinder temperature is investigated in terms of performance and emissions. The experiments were conducted in a variable compression CFR engine that was modified to operate in oxy-fuel mode with recycled carbon dioxide. The emissions were also measured using an FTIR exhaust analyzer. The results showed that the implementation of this concept is possible. However, the indicated thermal efficiency deteriorates due to lower combustion and gas exchange efficiencies. Also, the CO2 recirculation resulted in higher CO and unburned hydrocarbons (UHC) emissions
