Almost all the additives are useless. Even those used for branding a fuel.

Fuels, lubricants and engines were developed together for working together perfectly. A 0.001% or even a 1% additive won't change the way of the incineration and the energy transfer significantly.

Honestly, I do not used nanoparticles in fuel but all the statements sound marketing tricks. Although I worked in 12 years in the petrochemical industry in leadership positions (quality management included), somebody with a strong chemistry knowledge can give a more proper answer.

Dear Dr. Radics

I agree with you, what is the advantages from using high quality fuel but it cause diseases. Thank you for your contribution, and I wish we cooperate together in the future.

Regards

excellent thinking @dr. chaichan

we even do not know what these particles are, are they liquid droplets or solid bodies, but we do know that these are more related to aromatics content of the fuel, hence I am welcoming doping fossil fuels with aromatic free biodiesel

To complete the Istvan Raics answer.

When there is a particulate filter, the addition of liquid organic compounds (e g Cerium octoate or Iron Octoate) in the Diesel Fuel (this is the case for Peugeot engines) the objective is that, after combustion, the catalyst (Fe or Ce) should be inside the soot particulate and so being more efficient when the soot is collected on the filter.

In the Diesel fuel there are also additives for the cleaness of injectors, additives to avoid foaming when we fill the tank. For biodiesel there is also antioxidant additives. To that we have to mention the anti icing additives and so on.

I don't think nano particulates additive could bring advantages.

About the combustion speed it is impossible to obtain a mesurable effect with any compounds at low concentration.

Best regards

Dear Prof. Muhib

Thank you for your kind feeling.

Dear Prof. Kovacs

These particles are originally solids mixed with fuel using ultrasonic mixing to form a suspended fuel. Experiments have certainly shown a change in the suspension specification for the original fuel, but the problem is that combustion releases these very tiny particles into the air. Even exhaust gas-treating equipment after the engine exhaust can not collect or prevent it from emitting outward. The health effects of these substances when inhaled or touched skin are very serious, as indicated by many valuable scientific studies. Then, its risk doubles the risk of diesel or gasoline. The question here: What do we seek from such fuel?

Dear Prof. thank for your contribution and I wish you will support me in preventing the world from new dangerous fuel.

Dear Prof. Gateau

I agree with you, I also don't think nano particulates additive could bring advantages. The researchers must focus on new environment and human alternatives like hydrogen I think.

Thank you for your valuable contribution, and I wish you agree with me.

Regards

Dear Prof. Chaichan

Thank you for your answer. I agree with you. Hydrogen and Fuel Cells are good alternatives for environment.

Best regards

Hydrogen or electric vehicles have advantages for areas like the LA basin where CO2 form burning Hydrocarbons is a serious problem. But H2 is produced from Hydrocarbons typically at 70-80% thermal efficiency releasing more CO2 to the environment than continuing to burn Hydrocrabons.

Switching to H2 does create the possibility off capturing and sequestering CO2 at the H2 production site if the site is located near the proper geologic formations to hold the captured CO2.

Dear Dr Chaichan

Scientific research try to find the better fuel or to improve the existed ones. In this case, R&D trying to find better fuel consumption with lower exhaust emissions. It may succeed or fail. We have to wait for the final result when these new fuels become commercial.

I'd recommend to check Concave reports of Automotive Emissions MG

An interesting article I found re nanoparticle

https://www.azonano.com/article.aspx?ArticleID=3085

Environmental issues are a problem.

Don't forget not to add ethanol to diesel or biodiesel fuel.

When you add ethanol to biodiesel you decrease flash point and your fuel becomes under the safety rules values.

Dear Dr. Gateau

You are absolutely wright. However, as you know, ethanol has high octane number but very low cetane number that decrease the ethanol-diesel blend cetane number which reduce the engine performance. Adding ethanol to diesel needs adding cetane number improver. Here, we must study the effect of these additional materials impact on the performance and emissions each case alone.

Regards

Dear Prof. Chaichan

I think these researches are for research no more. This means all the results will lead to one answer: there is no hope in using such materials to enhance the engine performance and reduce its emissions.

Regards

Sir I agree with you that adding nanoparticle to diesel biodiesel blends leads to harmful emissions but we can have tunnel Technology to reduces such particulates from spreading in the environment and the use of nanoparticles have shown significant improvement in combustion and lowered harmful gases like CO and HC emissions.

This research has always been a point of discussion but due to the limited resources of crude oil researchers has always been trying to make alternatives for the fuel. Hydrogen fuel is a good option but due to high production and maintenance cost it is very difficult to commercialize it.

In all we researchers are always trying to overcome such issues and we hope that soon there will be a good alternative to the existing fuel technology in coming years.

Dear Dr Ninawe

Thank you for your valuable contribution. Can you benefit us with some studies about tunnel technology?

Regards

Dear Sir,

Here you can have a look at the article related to tunnel technology for the vehicle exhaust specially particulate matter emission.

Dear Dr Ninawe

Thank you for your valuable assistance.
