how does the fuel in the tank get converted into air mix?

Question

wont the fuel just sink down ito the into the piston chambers when its pumped from the tank??

Answer 1

If fuel is through a carburetor it is sucked into the engine by the induction of the piston travelling down the bore , the force is controlled by how far you press the throttle pedal as the suction pulls the neat fuel into the engine it mixes with the air pressure and is atomised and enters the piston chamber as a extremely fine mist it is then compressed and when at the highest compression is fired by the spark at the spark plug it then explodes driving the piston down creating thrust
injection is the same except the injector pressure is great enough to atomised the fuel. diesels work different in that the engine works under much greater pressures about 450 lb per square inch
diesel explodes at certain high pressures and does not need spark plugs . I hope that helps you i have kept it as simplistic as i can there is a great more to it than i have laid out

Answer 2

Is this a homework question?

The fuel pump transfers the fuel either to a carburettor or a fuel injector, which aerosols the fuel. The aerosol-ed fuel/air mixture can then become volatile in the combustion chamber. Valves regulate the intake of fuel and the outflow of exhaust gasses.

Motor vehicle fuel(for that matter, ANY fuel) is not combustable until it is mixed with air and heat.

Answer 3

It is the same process for both carburetted engines or fuel injected. Think about a plant water mister; same principle; liquid delivered under pressure forms a very fine mist, combined with air (which is often moist with fine water droplets). The fine gasoline droplets are combiend with the air as it enters the intake manifold and combustion chamber. If the injectors are blocked or carburetor is dirty, then yes you get larger drops.

Answer 4

No, either in a carburettor or by fuel injectors petrol is forced through very narrow jets into a fast flow of air. It is then available to the cylinders as a fine mist.

No it first mixes with air when it goes thru the carburetor or in the cylinder if it is fuel injection or thru the throttle body if it is a throttle body injection system.
