Question

What will be the effect if by mistake diesel fuel is supplied in a petrol engine?

यदि गलती से पेट्रोल इंजन में डीजल ईंधन डाल दिया जाए तो क्या प्रभाव पड़ेगा?

A.

Engine will not run 

B.

Engine will run at lower rpm 

C.

Engine will run at reduced efficiency 

D.

Engine will give dense smoke and will consume more fuel as well as lubricating oil

Answer ( Option A)

Engine will not run 

Solution

Gasoline requires an octane rating of 87-91. Since diesel fuel has an octane rating of 25-30, pumping diesel fuel into a gas tank can lower the octane level needed and cause damage to the engine.

As a result, Engine will not run.

Hence, the correct option is (A).

&Key Points:-

Octanerating is the measure of a fuel’s ability to resist knocking or pinging during combustion caused by the air/fuel mixture detonating prematurely in the engine.
