How exactly does turbo work on a car?

Question

I know some about it but I'd like to know more.

Answer 1

The way a turbo works is first the turbo itself. It has two blades that spin in the same direction but are cut differently depending on the side. On the one side is an exhaust side. On this side the exhaust from the engine enters and spins the blade. On the other side is the air intake or compressor side. This side sucks in the air and compresses it and sends it to either the intercooler or right into the engine itself. What a trubo does is increase the amount of air going into the engine, rasing compression in the cylinders giveing the car more power. When people talk about turbo lag that is the time it takes the exhaust to spin the turbo fast enough (spooling) to get boost.

Answer 2

Generally, turbo's use a portion of exhaust gases to drive the fan, which mixes with fresh air and fuel and puts pressure into the combustion chamber. The more air you shove into the combustion chamber with the same amount of fuel, the better the explosion, and work to be done, of pushing the piston down. But there is a lag, depending on how good of a turbo you want. A cheap one will have a longer lag time, meaning you have to produce exhaust gases in order for the turbo to activate at its full potential, so for example idle to say 2,000 rpms will be your normal engine working, then there will be enough exhaust gas to activate the turbo and it will take over giving you more horsepower.

Answer 3

Turbo is usually run by a pulley off the engine, it has a kind of fan that produces alot of air that is forced into the intake system where the air is then forced into the cylinders, thus providing more air to compress and create more power.A cars' engine usually relies on barometric pressure, maybe 15 lbs PSI, a turbo forces much more air into the system.The piston compresses this air along with the fuel and at ignition created by the sparkplug causes an explosion which forces the piston back down the cylinder known as the power stroke.

Answer 4

You sound pretty new to turbos

Let's not get too complicated. Just imagine the Turbo like a fan.

A fan that blows air into the engine

The turbo (fan) compress the air flowing into the engine

More air + more fuel to burn = more power

In reality, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump.

Answer 5

In a normally aspirated engine the maximum manifold pressure that you can attain is 14.7 lb. per sq. ft. at sea level. A turbo charger (normally spun by the exhaust gases) drives a turbo compressor which pressurizes the manifold, thereby providing a larger volume of air/fuel to enter the engine. This provides greater power in the engine at sea level and allows sea level pressures to be maintained at altitude.

Other types of turbos include gear driven, electrically powered and belt driven. A "waste gate" is also a normal part of a turbo which dumps escess air to maintain a maximum boost for the engine specification.

Answer 6

The exhaust drives a compressor (Turbo Charger) that compresses the air going into the engine. That results in more air flowing through the engine, and higher compression ratio in the combustion chambers. Both have a positive influence on horsepower.

Answer 7

easy simple answer

exhaust gas spins turbo

turbo pushes air in to motor...
