Mufflers and Tailpipes

Mufflers and tailpipes are components of an exhaust system. The tailpipes guide the exhaust away from the engine and into the muffler. The muffler reduces the noise coming from the engine through the tailpipe.

Which is more efficient efficiency of carnot engine increased by increasing temp of source or decreasing temp of sink?

That depends how much you increase the source, and how much you decrease the sink.

How efficient is a car?

Two basic ways: aerodynamic or small. Aerodynamic means the car doesn't push against the air as much, meaning it can slice through the wind easier. Making a car lighter and smaller means it doesn't need as much power, so you can reduce the size of the engine.

What are the symptoms of a hole in the muffler?

Generally a hold in the muffler will make your car sound excessively loud. Carbon Monoxide may also fill the cab of your car or truck and you should have it repaired as soon as possible to avoid exposure to lethal fumes.

What would cause a quick gush of white smoke to come out of the exhaust on a 1999 Dodge Caravan only upon starting?

White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result. How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).

Should you patch or just replace exhaust components if there's a small hole right before the muffler?

If the hole is smaller than a nickel, I would not worry about it. If the hole is on the bottom side of the exhaust pipe, it might actually be a good thing, as it would allow the water in the exhaust to drain out before it enters the muffler. Some newer cars have drain holes in the exhuast system to prevent things from rusting out quickly.

What causes a truck to have black smoke coming from the exhaust?

Black smoke is a sign of a vehicle running rich. I would check for a bad fuel pressure regulator, bad fuel injector or very plugged air filter.

A fuel pressure test could tell you much.

Will drilling holes in your stock exhaust give you the same results as a performance exhaust?

It will make the exhaust come out those holes instead of the the tail pipe. Just take your vehicle to a muffler shop and have them remove your muffler and put pipe in it's place. No restriction means more flow which means higher performance, unless your talking about a 2-stroke then don't f with it.

How do you remove an exhaust silencer?

I'm sure you've removed the screws but if not do that then get some pliers and give it a really strong tug, if that doesn't work try pushing a coat hanger thru and pulling the silencer out. failing that, run the car for about 20 minutes to heat the exhaust up and soften the metal and then try steps 1 and 2 again. (tip) if your going to try WD-40 don't spray it onto a burning hot exhaust
