what does flame point mean in relation to fuel and associated with flash point. In automobile engines.?

I've never heard the term "flame point" specifically.  I'm assuming it's the same as the flash point.  The flash point is the temperature at which the vapor pressure of a fuel is high enough to be ignited when in atmospheric air.  Gasoline has a flash point of -40 deg, so there is enough gasoline vapor to be ignitable at any temperature above that.  Diesel fuel has a flash point of well over 100 deg F, meaning that there is not enough Diesel vapor to be ignitable at room temperature.

The answer to that question depends on many factors.  However the military practices this phenom daily.  each element has a combustion point.  Freashman Physics does not delve into the properties of air friction as it relates to projectile motion.   \n\nnow for the basic answer.  I will leave the details for you to research.  Understanding science is much superior to being given a fish.\n\nTracer rounds in in military machine gunds are composed of standard bullets whose tips are coated with Phosphorous.  the are inserted every fourth round but when fired the velocity of round, its surface area, and the friction due to  air cause a net resultant heat that surpasses the combustion pint of Phosphorus.  My spelling sucks but hopefully my theory is sound.

It means you have an air leak in your emission system. No big deal, quite often a gas cap not sufficiently tightened. That will give you some idea of the problem.

Aviation Fuel. it's a specialised type of petroleum-based fuel used to power aircraft; it is generally of a higher quality than fuels used in less critical applications such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperatures, amongst other properties.\n\nAviation fuel is typically divided into two categories: Avgas, which is used in piston-engined aircraft, and jet fuel, which is used in jet-engined aircraft.

A flame is a mixture of gases undergoing a chemical reaction that gives off enough heat to continue the reaction in the molecules that have not yet reacted.  We get the impression that solids (like wood) burn, but it's really mainly the gases coming off of them that burn.  That's why it's easier to start a hot piece of wood on fire than a cold piece of wood.  The initial piece has to be hot enough so that the flamable products escape from it in vapor form.

Here's the answer to be very precise:\n\nTemperature without drawing:\n\nSide of the lit portion: 752 deg F\nMiddle of the lit portion: 1112 deg F\n\nTemperature during drawing:\n\nMiddle of the lit portion: 1292 deg F\n\nThus, if a burning cigarette falls on gasoline, it can instantaneously cause fire and explosion as the auto ignition temp of gasoline is around 500 deg F.

Engine usually refers to a thermodynamic device. It is through thermo processes that the liquid engine works. The solid is a motor because it relies on impulse.

Fire is basically a mixture of hot gases.\nHence it's state can be taken as gaseous.\nI thinks "fire" in your question means flame.\nIf flame is very hot, then gases nearby get ionized and we get plasma- another state of matter

Vehicle engine smoke.  Why?

It's all about the fumes.\n\n"Fumes", for the purposes of this answer, are gasoline vapors in an oxygen-rich environment (e.g., air).\n\nLiquid gasoline by itself will usually "drown" a lit match.  You need oxygen to sustain a fire, so if there aren't any fumes, the flame will die as the match becomes submerged, and loses its oxygen supply.\n\nIf there are gasoline fumes present, however, you'll lose a bit more than your eyebrows when the fireball comes.\n\nNote that this is how we get cars to run -- by injecting a fine, vapor-like spray of gasoline into an air-filled cylinder.

The performance rating of a diesel fuel, corresponding to the percentage of cetane in a cetane-methylnaphthalene mixture with the same ignition performance. A higher cetane number indicates greater fuel efficiency. Also called cetane rating.\n\n\n\nIn case of a petrol engine the term similar to cetane No is Octane no

flammable\nCapable of being easily ignited and burning rapidly\nAlso, having a flash point below 100 º Fahrenheit.\n\ninflammable\nSame as flammable. Capable of catching fire easily and burning rapidly. Also, having a flash point below 100 º Fahrenheit.

When something burns the vapor given of by the reaction between the fuel, oxygen and heat is what is actually burning.  The flame goes up because this vapor is less dense than the surrounding air.

"These substances" refers to what?\n\nThe product of combustion include the oxides of carbon-mono and di, water vapor, unburned hydrocarbons and mineral ash.

Condesates formed under high temp. and pressure can reach flash points suddenly. They usually combust with a flame whose characteristics depends on the material.\n\nIt can be used as reaction indicators or flashes.

Fire is the act of oxidizing fuel.  The hydrogen and oxygen are already bonded, so there's not fuel or oxygen.  Steam is just a state change, not a chemical reaction.
