What is volatility in fuel?
Answers
Answer:
The ability of a liquid to change to vapor is known as VOLATILITY. ... The volatility of fuel affects engine starting, length of warmup period, fuel distribution, and engine performance. (When compared to diesel fuel (F-76), gasoline is much more volatile.)
Answer:
The ability of a liquid to change to vapor is known as VOLATILITY.
Explanation:
All liquids tend to vaporize at atmospheric temperatures, but their rates of vaporization vary. The rate of vaporization increases as the temperature increases and as the pressure decreases. (Temperature is more important than pressure.) In general, for a given temperature, a highly volatile fuel will vaporize more readily and at a faster rate than a fuel with a lower volatility.
The volatility of fuel affects engine starting, length of warmup period, fuel distribution, and engine performance. (When compared to diesel fuel (F-76), gasoline is much more volatile.) High volatility, however, can also result in fuel dilution of the lube oil in the crank case. The ways in which volatility can affect engine operation are discussed in the sections that follow.
