Study Notes

European Standardization of Gasoline and Diesel Fuels

Euro Specifications are standards set by the European Committee for Standardization (CEN) to regulate the quality of gasoline and diesel fuels.
The first set of standards was introduced in 1993 and included the EN 228 standard aiming to improve automotive fuels quality, including lead and sulfur content.
The standards are constantly being updated to reflect changes in specifications, including mandatory reductions in sulfur content.
The 2009 directive introduced a Low Carbon Fuel Standard aiming to reduce greenhouse gas (GHG) emissions for road transport fuels.

Gasoline Properties and Octane Rating

Octane ratings measure a fuel's resistance to spontaneous ignition.
A higher octane rating indicates the fuel will burn slower.
Every engine has a specific octane number and using lower octane fuel can damage the engine in the long run.
Octane number decreases with increasing carbon chain length.
Normal Paraffin has a low octane number as the molecular weight increases, leading to lower octane ratings.
Certain impurities like lead and sulfur can decrease the octane rate.

European Gasoline Standards and Specifications

Three key properties impact engine performance:
- Antiknock characteristics
- Reid Vapor Pressure
- Boiling Range
Sulfur, Benzene, Aromatics, Lead, and Manganese are also critically monitored to produce gasoline of the desired quality.

Research Octane Number (RON) and Motor Octane Number (MON)

RON and MON measure a fuel's anti-knocking resistance.
Measured by comparing the fuel with a mixture of iso-octane (octane number 100) and n-heptane (octane number 0).
RON is based on low-speed city driving(600 rpm).
MON is based on high-speed highway driving(900 rpm).
Compression Ratio is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to the volume when the piston is at the top of its stroke.
Different octane levels are suitable for different vehicles based on their engine compression ratio.

Specific Octane Ratings and Applications

RON 88 is suitable for vehicles with a compression ratio of 9:1.
RON 90 is most commonly used in Indonesia and appropriate for vehicles with a compression ratio of 10:1.
RON 92 is for vehicles with EFI technology and a compression ratio ranging from 10:1 to 11:1.
RON 98 represents the highest octane level typically used in high-performance sports and premium vehicles with a compression ratio of 11:1 to 13:1.
RON 100 is the highest octane type used for high-compression racing engines with compression ratios of 13:1 and above.
