Viscosity acid content heating value ignition quality
increase ignition delay affect fuel oil metering affect engine performance at low speed only disappear due to fuel oil abrasion
The cetane number is obtained by comparing the fuel with cetane a colorless liquidhydrocarbon The higher the cetane number, the shorter the ignition lag The highest cetane number of fuel is 100 All of the above
The cetane number affects the amount of injection lag The cetane number is an indication of the fuels viscosity Ignition lag is reduced with fuels having a high cetane number The cetane number is of little significance in the combustion process
less fuel will enter the cylinder higher the cylinder combustion temperature more complete the fuel combustion more rapid the rise in combustion pressure
