Ray: So, gasoline is lighter, less dense, more flammable and more volatile. … Tom: Diesel fuel is heavier, denser, less flammable and less volatile. So to detonate it, it has to be compressed in a cylinder to a very high pressure and temperature, at which point it detonates without a spark.
Is petrol highly volatile?
Gasoline, also spelled gasolene, also called gas or petrol, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats.
Why is petrol so volatile?
Variable venturi) where petrol gets atomized (considering high volatility), and air and fuel mixture is compressed in the compression stroke hence pressure and temperature is increased yet spark is required to ignite this air and fuel mixture that’s why it is also known as spark ignited engine (SI) in which compression …
Is diesel fuel less volatile?
Diesel fuel, also called diesel oil, combustible liquid used as fuel for diesel engines, ordinarily obtained from fractions of crude oil that are less volatile than the fractions used in gasoline.
Is petrol more polluting than diesel?
On average, diesel vehicles are bigger, heavier and more efficient than petrol vehicles. … In general, it can be said that petrol vehicles are on average less polluting than diesel vehicles. They emit less fine particles, and even less CO2 as they are often smaller vehicles used for shorter travels.
Are diesels better than petrol?
Diesels deliver more power at lower engine revs than their petrol equivalent. This makes diesels feel more suited to longer motorway trips because they’re not working as hard as petrol engines to produce the same performance. This also helps to make diesel cars better suited for towing.
Which is more volatile petrol or kerosene?
Kerosene is less volatile than gasoline. Its flash point (the temperature at which it will generate a flammable vapour near its surface) is 38 °C (100 °F) or higher, whereas that of gasoline is as low as −40 °C (−40 °F). This property makes kerosene a relatively safe fuel to store and handle.
Which fuel is more volatile?
Ray: So, gasoline is lighter, less dense, more flammable and more volatile. When you spray gasoline into a cylinder, it starts to vaporize immediately, so that as soon as the spark plug fires, the gasoline detonates and powers the engine. Tom: Diesel fuel is heavier, denser, less flammable and less volatile.
Can you light diesel fuel on fire?
Diesel fuel can catch fire and is classified as a flammable liquid according to OSHA, because it has a flashpoint above 199.4 degrees Fahrenheit. The flashpoint of diesel is approximately 140 degrees Fahrenheit (60 Celsius). This means in most ambient temperatures it will not ignite.
Can you pour diesel on a fire?
Diesel is a fossil fuel and a combustible material. It can and will burn, when heated to a temperature high enough in presence of ample Oxygen to support a fire.
