Gasoline and diesel engines are both internal combustion engines,the gasoline engine needs a spark to ignite the air fuel mixture,while a diesel engine uses a high compression of the air-fuel mixture to ignite ,What is the difference between AWD, FWD, 4WD,4x4?
A gasoline engine is fired by combustion. A diesel engine is fired by compression. And of course, the fuels are entirely different.Car rental from Charlotte Airport for a 20 year old?
he "crude oil" pumped out of the ground is a black liquid called petroleum. This liquid contains aliphatic hydrocarbons, or hydrocarbons composed of nothing but hydrogen and carbon. The carbon atoms link together in chains of different lengths.Why have car manufacturers never installed compasses as standard equipment on cars?
It turns out that hydrocarbon molecules of different lengths have different properties and behaviors. For example, a chain with just one carbon atom in it (CH4) is the lightest chain, known as methane. Methane is a gas so light that it floats like helium. As the chains get longer, they get heavier.
The first four chains -- CH4 (methane), C2H6 (ethane), C3H8 (propane) and C4H10 (butane) -- are all gases, and they boil at -161, -88, -46 and -1 degrees F, respectively (-107, -67, -43 and -18 degrees C). The chains up through C18H32 or so are all liquids at room temperature, and the chains above C19 are all solids at room temperature.
What happens if you are 17 and get caught driving over...say...120 mph?
The different chain lengths have progressively higher boiling points, so they can be separated out by distillation. This is what happens in an oil refinery -- crude oil is heated and the different chains are pulled out by their vaporization temperatures. (See How Oil Refining Works for details.)
How much would be a paint job for a 2001 lincoln LS?
The chains in the C5, C6 and C7 range are all very light, easily vaporized, clear liquids called naphthas. They are used as solvents -- dry cleaning fluids can be made from these liquids, as well as paint solvents and other quick-drying products.
What is the biggest engine you can have without paying tax on it.?
The chains from C7H16 through C11H24 are blended together and used for gasoline. All of them vaporize at temperatures below the boiling point of water. That's why if you spill gasoline on the ground it evaporates very quickly.
Next is kerosene, in the C12 to C15 range, followed by diesel fuel and heavier fuel oils (like heating oil for houses).
Does anyone know where or how to install a secret compartment in a car?
Next come the lubricating oils. These oils no longer vaporize in any way at normal temperatures. For example, engine oil can run all day at 250 degrees F (121 degrees C) without vaporizing at all. Oils go from very light (like 3-in-1 oil) through various thicknesses of motor oil through very thick gear oils and then semi-solid greases. Vasoline falls in there as well.
What are the benefit(s) of Volkswagen New Bettle?
Chains above the C20 range form solids, starting with paraffin wax, then tar and finally asphaltic bitumen, which used to make asphalt roads.
Has any one know of a shipping company called planet lukacs gv cargoline?
All of these different substances come from crude oil. The only difference is the length of the carbon chains!
In the "cars and transportation,car makes" section,why is there no catagory for Rover cars?
Diesels have no spark plugs fuel is fired by the extrem compression which causes the fuel to heat up enough to auto matically combust...Can someone explain how diasle fuel is made?
they do have glow plugs for cold weather starting...
Where can i get a list of the fastest production cars and trucks from 05 to now?
crank shaft is very different the throws are 180 degrees apart instead of staggered around the circle on gas engines...
Being chased by someone in a mustang!!?
compression on a diesel is 23.9:1
Do those windshield sun blockers really work that well?
diesels are always injected not carbureted (no carburetor)
gas engine has spark plugs and some sort of igintion to ignite the fuel
crank throws are staggered around the circle i.e. for a V8 the throws for the rod s are ever 90 degrees for a V6 every 120 degrees
Things to check out before road trip?
gas can be carbureted or injected...
How many girls out there love the sound of a big block engine?
com pression ratios run fromabout 8.2:1, up to about 10.5:1 for an old Muscle car
note diesels have almost 3 times the compression of a gas engine
