HOMEMADE DIESEL FUEL

Diesel fuel made from natural oils and fats has a much lower cetane number than diesel made from hydrocarbon sources.

Diesel engines require a minimum cetane number to run correctly. In Europe, diesel fuel is manufactured to a European Union specification i.e. EU 590. Fuel meeting this specification has a minimum cetane number of 51 and premium diesel fuel can have a cetane number as high as 60.

Therefore, if you are making diesel fuel from a natural source it is necessary to add a cetane booster such as Hydra EHN-99 to your fuel, 2-EHN is the standard cetane booster, approved by all governments and used worldwide. It is not necessary for the product to contain a lubricant as there is sufficient lubricity from the fats and oils that the homemade diesel is made from.

Hydra EHN-99 delivers an increase in Cetane number to your Diesel and MGO fuel. It will increase the cetane number by up to 4 to 8 points depending on the quality of fuel being treated.

Hydra EHN-99 provides an economic route to meeting quality specifications and a platform for creating premium fuels. Diesel bug treatment improves fuel combustion by reducing the ignition delay period resulting in easier cold starting, reduction in white smoke, harmful emission reduction, and reduced noise from the engine. Better fuel combustion means improved fuel economy.

HYDRA EHN-99 delivers an increase in Cetane number to your Diesel and MGO fuel. It will increase the cetane number by up to 4 to 8 points depending on the quality of fuel being treated. Hydra EHN-99 provides an economic route to meeting quality specifications and a platform for creating premium fuels and it is perfectly suitable for all diesel and biodiesel fuel. Better fuel combustion means improved fuel Performance and Economy on any diesel engine.

 

IMPORTANCE OF CETANE

The overall quality of diesel fuel is dependent on a number of factors. These include BTU value, viscosity, pour flow point, aromatic and paraffinic content, and resistance to contaminant build-ups such as water and bacteria. A diesel fuel’s quality also is very dependent on its cetane number.

The cetane number (CN) is an index of the ignition point or combustion quality of diesel fuel and is measured using an ASTM D613 test. 

Standard European BS EN590 diesel from the pump normally has a minimum cetane number of around 51, with premium diesel a little higher. Depending on engine design, driving conditions, and so on, the optimum cetane value for most vehicles is around the mid to high 50s.

Matching cetane to the engine is important in order to maximize the engine’s performance. Biodiesel fuels in particular, especially homemade brews, usually start with a much lower cetane number so cetane improvement for these fuels is essential.

A fuel with too low of a cetane number for a particular engine will result in reduced cold-start ability, rough running, excess engine noise/vibration, and reduced combustion quality.

This leads to reduced performance, excess emissions, and carbon build-up throughout the engine and emission system components (intake, EGR, DPF etc.).

A higher cetane fuel that is a proper match for the engine will reduce ignition delay, improve overall combustion quality, liberate more BTU (energy) from the fuel, and improve performance and MPG. It also will reduce engine noise, deposit build-up, and exhaust emissions. 

Diesel and MGO fuels with cetane numbers lower than minimum engine requirements can cause rough engine operation. They are more difficult to start, especially in cold weather.

Many low cetane fuels increase engine deposits resulting in more smoke, increased exhaust emissions, and greater engine wear. Using fuels that meet engine operating requirements will improve cold starting, reduce smoke during start-up, improve fuel economy, reduce exhaust emissions, improve engine durability, and reduce noise and vibration.

Hydra EHN-99 delivers an increase in cetane number to your diesel and MGO fuel. It will increase the cetane number by up to 8 points depending on the quality of fuel being treated.

It provides an economic route to meeting quality specifications and a platform for creating premium fuels. Improves fuel combustion by reducing ignition delay.

 

What should I look for in a cetane booster?

Contrary to some propaganda, alkyl nitrates still offer the greatest improvement in cetane number, with measured increases of up to eight points. 

When it comes to alkyl nitrates, 2-Ethylhexyl nitrate (2-EHN) is the most popular and most respected.  

It offers more consistent ignition quality whilst reducing unwanted and negative combustion conditions.

Fuel additive manufacturers recognize both the benefits of boosting the cetane number and using 2-EHN so much now that most offer cetane improvers. 

 

The question, in this case, is what are you getting for your money?

From the close examination, it appears many cetane boosters contain useless fillers. To maximize profits most manufacturers still insist on the single bottle per tank philosophy. 

Some 200-300ml bottles that treat a single tank of fuel have as little as 20% active ingredients. 

This is lucrative for the manufacturer but not a good value for the consumer. Therefore, it is important to understand what you are getting for your money.

The optimum amount of 2-EHN is around 30-100ml per tank of fuel, depending on the engine and base cetane level. 

As 2-EHN can reduce lubricity it is important that the fuel contains sufficient lubrication. Home made bio-diesel is perfect for this as it has more lubricity than normal diesel.

To ensure you are getting the best value, make sure the product contains at least 50% 2-EHN.

Hydra EHN-99 is ideal as it is 99% pure 2-EHN (2-Ethyl Hexyl Nitrate).

 

So, what do we recommend and why?

Active cetane improvers are essentially a form of fuel modification, or more accurately, combustion modification.

When combined with the correct fuel catalyst technology, latest Nano detergents, and lubricity additives, they can turn the most mediocre pump fuels and biodiesels into super diesel that will outperform the best premium pump fuels.

Rather than introduce another diluted cetane booster, Hydra decided to release a concentrated chemical product that contains 99% active ingredients.

It provides optimum increases in cetane whilst being able to treat multiple tanks of fuel, rather than just one tank.

Hydra EHN-99 contains a minimum 99% 2-EHN this ensures that your fuel receives the maximum cetane boost. Giving an optimum combustion condition to ensure a better fuel burn, smoother engine and more mpg.

What is the best diesel cetane booster?

Alkyl nitrates give the greatest increase in cetane number, which they will increase by up to 8 points with measured increases of up to eight points.  The most used and most cost-effective alkyl nitrate is 2-EHN (2-ethylhexyl nitrate). It gives exceptionally good ignition reduction times whilst reducing harmful emissions.

Is cetane good for diesel?

All diesel engines require a minimum cetane number to operate at their most efficiency. Often cheap supermarket fuels have only the minimum cetane number to meet EU diesel fuel specifications. By increasing the cetane number you decrease the ignition delay giving better combustion and fuel efficiency

Is too much cetane bad?

The cetane number will only increase by a maximum of 8 points, and the increase will depend on the starting point number of your fuel. Therefore, if your cetane number is high to start with adding a lot more cetane will not make any difference. So, it is important to know what your current fuels cetane number is. If you do not know the number, then to save the maximum amount of money it is always a good idea to use a cheap supermarket fuel as your starting point.

How do you increase cetane number of diesel fuel?

Simply by adding 2-EHN, the higher the starting number the higher the concentration of cetane booster already in the fuel. It costs the refineries money to add cetane therefore generally speaking the cheaper the diesel fuels the lower the concentration of cetane already in the fuel.

Better mpg with incredable smooth running
Monday, 19 March 2018  | 

My Renault was juddering badly when I accelerated so I thought I would try this product. I was amazed as the juddering stopped and my car is now running smoothly. Also after adding 100 ml to the tank my MPG has vastly improved.
