What does 95 and 98 gasoline mean?
1 Answers
95# and 98# refer to the octane rating of gasoline. Here is the relevant information: 1. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, and mainly consists of C5 to C12 aliphatic hydrocarbons and naphthenes. 2. Difference: The higher the octane rating of gasoline, the better its stability. Some cars require 95 gasoline to prevent engine knocking, which is an abnormal combustion phenomenon in the engine. Knocking occurs during the compression stroke and is caused by insufficient stability of the gasoline.
