The property of ignition lag is generally measured in terms of retane number. Cetane, straight-chain paraffin with good ignition quality, is arbitrarily assigned a rating of 100 cetane number. It is mixed with alpha-methyl-naphthalene, a hydrocarbon with poor ignition quality, which is assigned 0 cetane number.
Rajat said: 5 years ago
Cetane as 100 while alpha methyl naphthalene is 0. So it is normal chain paraffin (paraffin).

Naphthalene is used in race cars as a booster fuel.
Chinmaya G A said: 5 years ago
Sir why naphthalene only using? Explain.

Parrafine is more suitable for CI engine and aromatic is used for SI engine.

The paraffin are major constituents of natural gas and petroleum. Branched-chain paraffins have a much higher octane number rating than straight-chain paraffins and, therefore, are the more desirable constituents of gasoline. The hydrocarbons are immiscible with water. All paraffins are colourless.
