What causes sparks out my exhaust?

The demand for additional power will instead flood the combustion chambers with more fuel to compensate for the poor burning. This fuel wastage increases the fuel consumption as the un-burnt fuel air mixture is evacuated as exhaust to cause the smell from your exhaust pipe and sometimes sparks.

Why does my car crackle when I rev it?

When an engine is running rich, it has too much fuel and too little air, which slows down the combustion process. When combustion doesn’t happen in a timely manner, the exhaust valve opens while the air-fuel mixture is still igniting, causing this explosion to “spill” out of the cylinder, making a loud popping noise.

What causes exhaust pops and bangs?

“Pops and bangs” are created by unburned fuel in the exhaust system. When excess fuel enters the exhaust system it increases in temperature and ignites inside the exhaust instead of the combustion chamber. The noise can be exaggerated by fitting a decat or full decat exhaust system.

Why is there white smoke coming out of my tailpipe?

A leaking or blown head gasket can allow coolant to enter the combustion chamber. This results in white smoke coming from the tailpipe, usually accompanied by a sweet smell. It’s also possible that your engine will overheat. Solution: Your engine will need to be partially disassembled, have the gasket replaced, and then be reassembled.

How does a bad tailpipe affect a car?

Vibrations: A bad tailpipe can affect the balance and operation of the entire exhaust system, which is suspended underneath the car with rubber hangers. This can cause parts of the exhaust system to contact the car’s underbody, creating vibrations that reverberate through the car’s structure.

Why is there smoke coming out of the back of my car?
