PARAMETERS DETERMINING OCTANE NUMBER


1. EFFECT OF COMPRESSION RATIO

For a typical carburetted engine without engine management.

Compression Octane Number Brake Thermal Efficiency Ratio Requirement ( Full Throttle )5:1 72 -6:1 81 25 %7:1 87 28 %8:1 92 30 %9:1 96 32 %10:1 100 33 %11:1 104 34 %12:1 108 35 %

2.EFFECT OF CHANGING AIR- FUEL RATIO

- Traditionally, the greatest tendency to knock was near 13.5:1 air-fuel ratio for engine specific.

- Modern engines, with engine management systems, now have their maximum octane requirement near to 14.5:1

- maximum power occurs around air-fuel 12-13:1 (Rich), maximum thermal efficiency occurs around air-fuel 16-18:1 (Lean)


3. EFFECT OF CHANGING THE IGNITION TIMING

• The tendency to knock increases as spark advance is increased.

• For an engine with recommended 6 degrees BTDC ( Before Top Dead Centre ) timing and 93 octane fuel, retarding the spark 4 degrees lowers the octane requirement to 91, whereas advancing it 8 degrees requires 96 octane fuel

- Basic Ignition Timing• Vehicle Retarded 5 degrees Standard Advanced 5 degrees• A 88 91 93• B 86 90.5 94.5• C 85.5 88 90• D 84 87.5 91• E 82.5 87 90


4. EFFECT OF TEMPATURE &LOAD

• Increasing the engine temperature, particularly the air-fuel charge temperature, increases the tendency to knock.

• Knock increases as load increases

5. EFFECT OF ENGINE SPEED

Faster engine speed reduces the tendency to knock



6. EFFECT OF ENGINE DEPOSITS, AIR TEMPERATURE, ALTITUDE, HUMIDITY.

• A new engine may only require a fuel of 6-9 octane numbers lower than the same engine after 25,000 km. The deposits produce the ORI by several mechanisms:- They reduce the combustion chamber volume, effectively

increasing the compression ratio. - They also reduce thermal conductivity, thus increasing the

combustion chamber temperatures. - They catalyse undesirable pre-flame reactions that produce end

gases with low autoignition temperatures. • An increase in ambient air temperature of 5.6C increases the octane

requirement of an engine by 0.44 - 0.54 MON• Octane number requirement decreased by 1.0 - 1.9 RON/300m.

• An increase of absolute humidity of 1.0 g water/kg of dry air lowers the octane requirement of an engine by 0.25 - 0.32 MON.


7. EFFECT OF ENGINE MANAGEMENT SYSTEMS

• Engine management systems are now an important part of the strategy to reduce automotive pollution.

• A modern engine management system can compensate for altitude, ambient air temperature, and fuel octane. The management system will also control cold start settings, and other operational parameters.

• a new requirement that the engine management system also contain an on-board diagnostic function that warns of malfunctions such as engine misfire, exhaust catalyst failure, and evaporative emissions failure.

• The use of fuel of too low octane can actually result in both a loss of fuel economy and power, as the management system may have to move the engine settings to a less efficient part of theperformance map. The system retards the ignition timing until only trace knock is detected.
