Petroleum crude oil is used to make gasoline, which is used in spark-ignited internal combustion engines. Conventional gasoline is primarily a blended mixture of more than 200 distinct hydrocarbon liquids, ranging in carbon atom count from four to eleven or twelve. It has an initial boiling point of around 35 C (95 F) at atmospheric pressure and a final boiling temperature of around 200 C (395 F). Gasoline is mostly utilized as a fuel for internal combustion engines in automobiles and some light airplanes.
Although it is a liquid rather than a gas, the term “gasoline” is widely used in Canada and the United States, and it is frequently abbreviated to simply “gas.” In fact, gasoline-dispensing establishments are known as “gas stations.”
Most current or former Commonwealth countries refer to petroleum as “petrol,” and their dispensing terminals as “petrol stations.” Sometimes the name “petrogasoline” is used. The name “benzin” (or a version of that word) is used to refer to gasoline in several European countries and abroad.
In aviation, the term “mogas” (short for “motor gasoline”) is used to differentiate automotive vehicle fuel from aviation fuel, also known as “avgas.”
What is the temperature at which gasoline vaporizes?
When modern injection motors fail after a long journey, some may not be able to be restarted right away. This is due to the fact that those modern motors can achieve temperatures of up to 120140 C, which are conducive to vapor lock.
What is 87 octane gasoline’s boiling point?
Gas does not “boil,” but it does vaporize (evaporate) at temperatures over 93 degrees F. The “boiling point” of standard 87 unleaded, as I understand it, is around 181 degrees, but this will vary depending on pressure and additives in the gas.
What happens when gasoline is heated?
When you heat a gas, its vapor pressure rises, as does the volume it takes up. The temperature of the gas rises as the individual gas particles grow more energetic.
Is it possible to boil diesel?
Diesel fuel has a greater boiling range (between 160C and 371C) and contains more nonvolatile components than gasoline (Table 4). As a result, diesel fuel must be sprayed rather than evaporated in the air to avoid pre-ignition.
Is it true that a higher octane gas prevents vapor lock?
The majority of gas vehicles from WWII were intended to run on very low octane fuel. They aren’t high-compression engines, and pre-ignition is rarely an issue. When used as an octane booster, high octane gas is both unneeded and can increase the likelihood of vapor lock by introducing larger levels of ethanol.
Hopefully, this explanation of gasoline, ethanol, and vapor locks will prevent you from standing on the side of the road, hood up, wondering if you should have used a different quality of gas. The first step toward keeping our historic military vehicles rolling is to understand how gasoline reacts to your vehicle and the environment.
How can the boiling point of gasoline be raised?
Toss in some thick ends. It will function with kerosene diesel fuel or stove oil. The boiling point of the fuel will be raised, but the octane will be reduced. If your car’s compression is low, a lower octane won’t affect it.
What happens if you put sugar in a gas tank?
If there’s too much sugar in the system, it can clog the fuel injectors or the fuel filter, just like any other debris. This may necessitate the replacement of the fuel filter or possibly the emptying of the gas tank. This means it’s a nefarious ruse that will cost you money, but not quite as much as complete engine devastation.
What is the temperature at which ethanol gas boils?
Because gasoline is not a pure substance, it has no one boiling point. Instead, at 90-100 degrees F, the lighter fractions begin to boil out, with more and more evaporating as the liquid temperature rises, until the ultimate, heaviest fractions evaporate at 300-400 degrees F. The “distillation curve” describes this phenomenon. Water boils at 212 degrees F, while ethanol boils at 178.5 degrees F. When fuel is atomized in a carburetor, the key is to make it evaporate into vapors without reducing the boiling point.
