A car backfires because unburned fuel is getting to the muffler. The heat of the exhause system causes the fuel to combust, thus a backfire.

I have just been told that the rubber on my exhaust has split - could this be why the car would backfire?

I have heard something about air getting into the exhaust could cause a backfire?

back fire can be caused by different faults. first is to much fuel because of worn carburetter, or wrong adjusments on carburetter. choke sticking will cause backfire. timing be out of adjustment will cause backfire exhaust leak can cause backfire. bad spark plugs, or plug leads , distributer cap worn of cracked will cause backfire as for fuel in muffler, if it combusted in muffler , the muffler would split open it is not that. and i dont know of any rubber on an exhaust that would take the heat aexhaust manifold gaskets could be problem but if they were rubber they would melt \

is it good or bad to have backfire

It can also be done with intentional modification, such as done in ''Keeping Up Appearances'' British sitcom. A fuel line and an oxidizer line are added to the muffler with a manual rubber bulb pump added to the line as the ''backfire button.'' At a point before entering the muffler, the lines have a pair of backflow valves to prevent the flame from racing into the mixture tanks. Squeezing the bulbs dispense a mixture of pure alcohol and an oxidizer into the muffler to create a reaction. For Onslow's car in the TV programme, copier toner was squirted in the tailpipe for a heavy soot effect on the backfire command.

Having a car backfire can shake off any parts that aren't bolted completely, and can cause the engine to stall because the pressure of the backfire can temporarily disrupt the exhaust release from the engine.

Besides, it would spook horses, cows, or anyone not used to loud noises. So having the car backfire down a Harlem road won't have the same effect, as a car backfiring down a rural city road.

A car can backfire and die if the spark plugs are bad. The car could also have a problem with the timing or the catalytic converter .

No! A car backfires because unburned fuel is getting to the muffler. The heat of the exhause system causes the fuel to combust, thus a backfire. A bad alternator will just not charge your car battery.

Its either too much fuel coming from the carbeuator and causing it to backfire or it could be spark plugs wired wrong. try to be more specific on where backfire is coming from. either out of the carbeuator or the tailpipes.

Your car is running too rich.

The main causes of backfire in any car are incorrect ignition timing, crossed sparkplug wires or worn timing belt (or chains and sprockets).

Backfire is an explosion produced by a running internal combustion engine that occurs in the intake or exhaust system rather than inside the combustion chamber,

Cars do backfire because of the mechanical failures.

As far as dangerous to humans, probably the only serious risk is to hearing. As far as dangerous to the vehicle, the backfire can certainly cause minor damage, especially to some carburetor diaphrams (especially Holleys). A backfire can also shoot flames or hot gases out of the carburetor, burning anything in the way.

The duration of Backfire - film - is 1.5 hours.

If any car backfires it is usually due to retarded timing, running lean or a problem in the valve train.

Internal combustion engines can backfire. In order to prevent flames from the backfire causing a fire on board, an approved backfire flame arrestor must be attached to the air intake with a flame tight connection.

You would have to call 911!Another AnswerSounds like the timing is off or plug wires in the wrong order.

I think you are hearing pressure pops. Not a backfire.

A rototiller may backfire when it is starting because the valves need to be adjusted. Another reason that it might backfire is because you have to replace the spark plug.
