Questions about Analytical Testing of Fuel

Can you determine whether fuel which has been stored for a long time for emergency is usable or not?

We cannot make an overall determination if it is usable or not. However, if there are criteria for controlling the oil, we can make comparison by determining control items.

Can you evaluate and analyze whether an oil is an illegal fuel oil?

Mixture of kerosene and heavy oil can be presumed by analysis of the fuel oil indicator (Coumarin).
Also, by performing sulfuric and Gas Chromatography analysis as well, it enables us to assume contaminated grade.

Is there any correlation between Cetane number and Cetane index?

JIS K2280 states “diesel fuel oil without Cetane improver indicates the equivalent value as Cetane number.　However, Cetane index cannot be abstracted from diesel fuel oil with Cetane improver.” These is relatively an intimate correlation with petroleum-fuel.

Can you measure Octane number of a fuel with alcohol?

Yes. However, JIS specification allows ethyl alcohol within 25%.
Measurements of alcohol concentration of 25% or more are for reference only.

Can you perform component analysis by Gas Chromatography for a fuel with alcohol?

Yes. However, in some cases, analysis is not possible because of a duplication of component depending on a type of alcohol.

What is the difference between JPI method and IP method for fuel oil composition analysis? Is there any correlation on data?

JPI method is mainly used in Japan, and it reports saturates, Olefin content and aroma contents (mono-, di-, and ply aromatic [TRI+]).
On the other hand, IP method is mainly used in Europe, and it reports only aroma contents (mono-, di-, and ply aromatic [TRI+]).
There is a tendency of having correlation on data to some extent, but we may not be able to make determination sometimes depending on a difference of test material.

Questions about Testing of Lubricants

Can you determine if lubricant which has been in use for a machine still can be used?

We cannot make an overall determination if it is usable or not. However, if there are criteria for controlling the lubricant, we can make comparison by determining control items.

We can secure only a small amount of sample. Can you determine what kind of grease it is?

We might be able to determine a type of grease by infrared spectroscopy in some cases. Please contact us.

Can you determine cone penetration with small amount of sample?

Determination can be performed with 5g of sample at the smallest, but in some cases, correlation cannot be obtained depending on a type of grease, compared with the determination using regular amount of sample. We recommend using the standard amount of sample of 300g for precise determination result.

Questions about Engine Test

Can we bring our own engine?

You can bring your engine, or we can arrange them.
Please contact us which type of engine is available.

Can you arrange fuel for testing?

We can arrange fuel on the market or we can blend special fuel by your request.
We can also only sell special fuels, so please contact us.

Can you disassemble an engine alone?

We can disassemble engine if you need.

Can I specify a driving pattern?

We can run by wide range of settings such as arbitrary operation patterns and various temperature settings.

Can you continuous operation possible?

We can run 24hrs a day and can take sample as you want.

Can you accept a long term testing?

We can operate for more than 1000 hours, so please contact us.

Can you evaluate engine parts?

We are fully equipped with precision equipment for measuring dimensions, surface roughness, and weight, and can take photos.

Can you possible to analyze the oil used?

Analysis of the fuel and lubricating used oil is performed on site, so we can quickly analyze sample during the test.
Please contact us analysis items.

Other Questions

Can we ask for a testing which is not on your test item list?

We might be able to accept a testing which is not described on our list. Please feel free to contact us.

Can you analyze sulfated pitch?

No, we do not undertake the analysis of sulfated pitch.

Can you perform test and analysis of insulating oil with PCB (Poly Chlorinated Biphenyl)?

No, we do not undertake the test and analysis of insulation oil with PCB.

Can I have the sample returned after the test?

Yes, but we need additional cost.

What is the minimum quantity when producing special fuel?

Manufactured products are 20L and imported products are 200L.

What types of packing special fuels are?

We can deliver in pails or drums.
