Use of nanoparticles as fuel additives is a popular subject matter for research. However, almost all studies are on nanofuels that are diesel or biodiesel based. Why are nanoparticle additives not employed in Petrol Engines (SI Engines) for enhancing combustion rate and quality of emissions?
I believe nano particles can be used as fuel additives in both SI and CI engines, and in both fossil fuels and biofuels. I am aware of some ongoing research in this area. I believe that sooner than later, we will have a clear research trend on the subject matter.
Nano particles increase heat transfer thereby promote combustion, causing higher heat release rate leading to increase temperatures nearer to SIT of the fuel may cause knocking for SI engines.
Dear sir,
Thanks a lot for this question. Thanks so much for all contributors. I'am agree with Dr. Hamit Can and Dr. Kaisan Muhammad Usman . Tha nano particles can be used as fuel additives for many reason such as goog combustion with high efficiency, etc. I recommend also the answer of Maddali V S Murali Krishna, because the combustion of fuel in an engine is a set of several difficult phenomena. So, the presence of nano particles, in fuel, is certainly a good factor of combustioni efficiency.
with my best regards!
Dr. Adel OUESLATI
The concluding remarks given by Dr Adel QUESLATI are good regarding this question. Nano particles improve combustion but it also causes combustion problems .
Dear Professor,
Nano particles increase heat transfer rate in a CI Engines up to certain level.But in a SI Engines it leads to Knocking problems.

I recommend also the answer of Prof. Maddali V S Murali Krishna because of the combustion problems. In addition, the exhaust emissions from the diesel engine at cold start, low load/speed operation when exhaust temperature may not be adequate for NOx reduction as compared with petrol engines.
