QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

### Blending of fuel is the process of

Solution:
QUESTION: 4

Consider the following statements:
1. For SI engines fuels most preferred are aromatics.
2. Paraffins are most preferred for Cl engine fuels.
3. Ignition quality of diesel fuel is indicated by its cetane number.
4. Normal paraffins exhibit the best antiknock quality when used in an SI engine.

Which of these statements are valid ?

Solution:

Normal paraffins exhibit the poorest antiknock quality when used in an SI engine. The antiknock quality improves with the increasing number of carbon atoms and the compactness of the molecular structure. The aromatics offer the best resistance to knocking in Si engines.

QUESTION: 5

Consider the following statements:
1. The normal paraffins are the best fuels for Cl engines.
2. Heating value of hydrogen is higher than carbon.
3. Paraffins have lower heating value than aromatics.
4. Fuels with fewer atoms are more volatile,

QUESTION: 8

Which of the following methanol composition has no methanol ?

Solution:

M 0 : Pure gasoline
M 15 :15% methanol and rest gasoline
M 85 :85% methanol and rest gasoline
M 100: Pure methanol

QUESTION: 9

Consider the following advantages of alcohol as a fuel.
1. It is a high octane fuel.
2. It produces, less emissions as compared to gasoline.
3. It has high latent heat of vaporization.
4. it has low sulphur content.
5. There is no possibility of vapor lock in fuel delivery system.

Which of the above are correct?

Solution:
QUESTION: 10

Small amount of gasoline is often added to alcohol to

Solution:

Alcohol does not vaporize as easily as gasoline. Its latent heat of vaporization is much higher. This affects cold weather starting. Gasoline is introduced in the engine to overcome cold weather starting. It helps in quick engine warming.
