15 PARAMETERS DETERMINING OCTANE NUMBER. Compression ratio 2. Air- fuel ratio 3. Ignition timing 4. Effect of temparature & load 5. Engine speed 6.Engine deposit, air temperature, altitude, humidity 7.Engine management systems

16 PARAMETERS DETERMINING OCTANE NUMBER. EFFECT OF COMPRESSION RATIO For a typical carburetted engine without engine management. Compression Octane Number Brake Thermal Efficiency Ratio Requirement ( Full Throttle ) 5: 72-6: 8 25 % 7: % 8: % 9: % 0: % : % 2: %

17 PARAMETERS DETERMINING OCTANE NUMBER 2.EFFECT OF CHANGING AIR- FUEL RATIO - Traditionally, the greatest tendency to knock was near 3.5: air-fuel ratio for engine specific. - Modern engines, with engine management systems, now have their maximum octane requirement near to 4.5: - maximum power occurs around air-fuel 2-3: (Rich), maximum thermal efficiency occurs around air-fuel 6-8: (Lean)

18 PARAMETERS DETERMINING OCTANE NUMBER 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 9, whereas advancing it 8 degrees requires 96 octane fuel - Basic Ignition Timing Vehicle Retarded 5 degrees Standard Advanced 5 degrees A B C D E

19 PARAMETERS DETERMINING OCTANE NUMBER 4. EFFECT OF TEMPATURE &LOAD Increasing the engine temperature, particularly the airfuel 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

20 PARAMETERS DETERMINING OCTANE NUMBER 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 MON Octane number requirement decreased by RON/300m. An increase of absolute humidity of.0 g water/kg of dry air lowers the octane requirement of an engine by MON.

21 PARAMETERS DETERMINING OCTANE NUMBER 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 the performance map. The system retards the ignition timing until only trace knock is detected.
