Question

The flash point of the oil should be sufficiently high so as to avoid flashing of oil vapours at the temperatures occurring in common use.

(a) True

(b) False

The question was asked in semester exam.

The above asked question is from Properties of Lubrication topic in chapter Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(a) True

The flash point of the oil should be sufficiently high to prevent the oil vapors from igniting at the temperatures commonly encountered during engine operation. If the flash point is too low, the oil can vaporize at normal operating temperatures, which increases the risk of ignition and potentially causes engine problems or safety hazards. Therefore, lubricants are designed with a flash point that ensures they remain stable and safe under typical operating conditions.
