Alcohols are not suitable as diesel engine fuel because the cetane number of alcohols is____________________?
Correct answer: A. Very low which prevents their ignition by compression
- A. Very low which prevents their ignition by compression
- B. Very high which prevents their ignition by compression
- C. Zero
- D. None of these
Explanation
Cetane number measures the readiness of a diesel fuel to ignite under compression, and alcohols have very low cetane numbers. Consequently, they have poor compression-ignition characteristics in diesel engines.
