Test: Conventional & Alternative Fuels Of IC Engine - 1 - Mechanical Engineering MCQ

Crude petroleum, as obtained from the oil wells contains gases and certain impurities such as water, solids etc. The crude oil is separated into gasoline, kerosine, fuel oil etc. by the process of fractional distillation. In the first step, the petroleum is passed through a separator in which gases are removed and a product known as natural gasoline is obtained.

It is the process of converting olefins, the unsaturated products of cracking, into heavier and stable compounds.

Pour point of fuel oil is the minimum temperature to which oil is heated in order to give off inflammable vapours in sufficient quantity to ignite momentarily when brought in contact with a flame.

Volatility of diesel fuel oil is Indicated by 90% distillation temperature, i.e., when 90% of sample oil has distilled off. Volatility refers to how easily a fuel vaporizes. It affects how easily you can start your car, warm it up, and how well it runs.

Reformation is a type of cracking process which is used to convert the low antiknock quality stocks into gasolines of higher octane rating. It do'es not increase the total gasoline volume.

Propane -  LPG

Butane -  Blended with motor gasoline to increase its volatility

Kerosene - Aviation fuels

Heavy gas oil - Blended with motor gasoline to increase its volatility.
