2. Micro carbon residue - Wikipedia

   en.wikipedia.org/wiki/Micro_Carbon_Residue

   For burner fuel, MCR provides an approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. [ 5 ] For diesel fuel , MCR correlates approximately with combustion chamber deposits, provided that alkyl nitrates are absent, or if present, that the test is performed on the base fuel without additive.

3. Fuel polishing - Wikipedia

   en.wikipedia.org/wiki/Fuel_polishing

   This fuel contamination, also known as 'fuel bugs', or 'diesel bugs', or 'so-called algae' build up over time in stored fuels if they aren't tested and treated on a regular basis. Fuel analysis should be undertaken before fuel polishing is commenced so that the exact contamination problem can be rectified with a targeted solution.

   For burner fuel, Concarbon provides an approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. [ 4 ] For diesel fuel , Concarbon correlates approximately with combustion chamber deposits, provided that alkyl nitrates are absent, or if present, that the test is performed on the base fuel without ...

5. Winter diesel fuel - Wikipedia

   en.wikipedia.org/wiki/Winter_diesel_fuel

   In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...

6. Microbial contamination of diesel fuel - Wikipedia

   en.wikipedia.org/wiki/Microbial_contamination_of...

   Water can get into diesel fuel as a result of condensation, rainwater penetration or adsorption from the air — modern biodiesel is especially hygroscopic. The presence of water then encourages microbial growth which either occurs at the interface between the oil and water or on the tank walls, depending on whether the microbes need oxygen .

7. Orsat gas analyser - Wikipedia

   en.wikipedia.org/wiki/Orsat_gas_analyser

   An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use. [1]
