do all car have carberators and what do they do?

Question

does a 1994 honda accord have one

Answer 1

Carburetors are an old method of mixing fuel with the right amount of air to provide optimum combustion when lit in the combustion chamber. Basically, it performs the same function as a fuel injection system, and in much the same way--it's just that carburetors are a mechanical system, and fuel injection is controlled by a computer.

Most cars built after the late 1980's have fuel injection. From the pictures I found online, I can tell you a 1994 Accord has fuel injection.

Answer 2

A 1994 accord does not have a carberator. It has fuel injectors. A carb was used on mostly every car until about the mid 1980's, with a few exceptions. A carberator atomizes the fuel and mixes it with the air coming in, and puts this mix into the intake manifold, which leads to the cylinders. When the mix is in the cylinder, it is ignited by the spark plug. A fuel injection system is usually much more efficient than a carb, since it uses less fuel. All cars after 1986 are not fuel injected as it says below. For example 1986-1989 Chevy Caprices.

Answer 3

Most cars these days are fuel-injected, and have been so for some time. There are still places in the world where you can buy new cars with carbuerators, however.

Fuel injection started appearing in the late fifties, I think, in a few sports cars. The Corvette,for instance, had FI as an option prior to 1960.

Back to the subject at hand: you can get a good rundown of how they work at www.howthingswork.com. However, here's a summary...

In order to run, an engine needs fuel, and it needs air. The fuel is provided in liquid state, and is mixed with the incoming air before it enters the engine to be burned. There are many ways to mix the fuel and air, but all methods require that the fuel be vaporized; that is, it can't enter the engine in a liquid state.

In a fuel injected engine, the fuel is squirted as a mist directly into the combustion chamber, or into the throttle body, where it mixes with the air. In a carbuerator, air draws fuel out through an opening, and in doing so the fuel becomes vaporized and mixes with the air.

Have you ever attached a bottle of lawn fertilizer to a garden hose, where the high-speed passage of the water across the top of the bottle causes the liquid fertilizer to be pulled out of the bottle and into the path of the water? The effect is similar in a carbuerator, except that air (rather than water) is flowing at high speed across the opening to draw out the fuel.

That's an oversimplification, but you get the point.

In such a system, you control the amount of fuel being pulled by controlling the amount of air that passes through; the throttle plate(s) do this by changing the size of the passage. You control the amount of fuel relative to the air by changing the size of the opening that the fuel is pulled through; this is done with needles and jets and whatnot.

Answer 4

All cars built after '86 are fuel injected. A carburetor is a device which mechanically mixes air with fuel. Fuel injection uses sensors and injectors to mix the fuel.
