Turbocharger turbine

The size, shape and orientation of the blades of the turbine is essential for the correct operation of the turbocharger. The turbo speed reached is directly proportional to the surface of the turbine blades hits the exhaust gases and affect the shape and orientation of the thrust force. This will also affect the so-called ” late “motor or lag (see next item). The right design will optimize turbine engine speed at which enters the turbocharger operation, and thus minimize the lag. If the turbine is very large and heavy, will provide a large increase in engine power, but the engine will require a very high speed to begin working. A very light and small turbine come to operate at a relatively low engine speed, but the additional power that may provide the engine will be minimal.

Turbocharger Design Considerations

There are several issues to be discussed when talking about turbochargers, especially if you want to install one in a car. A detailed consideration of the most important.

Heat engine and mechanical stress

It is an expected effect of a turbocharged engine, is burning more fuel mixture in each cycle, which creates a stronger explosion, but also generates more heat. The higher the engine speed, more fuel is burned, which generates even more heat. In some cases, may be manifold and turbocharger red hot, allowing to get an idea of ​​the high temperature that must support these components. This should be taken into account when deciding which model turbo install, how much compression, etc, because if the heat generated exceeds the design limits of the engine, or if the blasts generated are too strong, you may leave damaging motor slowly, significantly shortening his life. In extreme cases, can be catastrophic engine failure at high speeds, which can have disastrous consequences for the occupants of the vehicle.

Components of a turbocharger

A turbo is usually positioned so that the turbine is directly after the exhaust pipe (or manifold ) engine, to take advantage of the exhaust it.On the other hand, connects the air compressor to the air intake pipe of the engine. Usually turbos include an intercooler , which is essentially a radiator that cools the compressed air before it is sent to the cylinders. Since cold air holds less volume than the same hot air, to send more fuel mixture to the cylinders, and this increases the efficiency of the turbocharger.

Usually the turbo compressor is a type of centrifuge , which draws air through the center, and expels the compressed air to a “snail” at the ends, which gives its peculiar shape.

Turbochargers, and to a lesser extent, superchargers have become very popular in recent years with the race fans and fast cars. A turbocharger is capable of increasing engine power significantly, adding little weight.

In this article, we’ll see what makes a turbocharger to increase engine power, using the latest technology ceramic bearings and turbines. If you love cars and engines with the latest technology, this article is for you.

Fundamentals of a turbocharger

What makes them so popular to the turbochargers in performance vehicles? The most attractive is, without doubt, the ability to add up to 50% more power to a motor, without making significant changes, and reasonably priced. All this can make a turbo (or turbo as is usually called) by adding very little weight to a vehicle.But, how?

The most common damage to faulty turbochargers

Impact damage
Impact damage due to ingress of foreign bodies into the turbine or compressor housing can be seen clearly on the compressor and turbine. When installing a new air intake duct to the turbocharger and the exhaust manifold should be checked for foreign objects.Attention! Turbocharger with such damage may continue to be operated under any circumstances.

Dirty oil
Dirty oil causes damage in turbocharged form of scoring on the bearing surfaces. Where does dirty oil?
• Engine wear by abrasion
• Inferior oil
• Poor quality or blockage of the oil filter
• Often, after an engine overhaul by inadequately cleaned oil ducts in the engine

Installation of a turbocharging system will add more complexity to the engine operation, thus troubleshooting a turbocharged engine will be more difficult than troubleshooting a naturally aspirated engine. A turbocharger consists of three basic components: the turbine, compressor, and wastegate. There are also additional components that are part of the basic components.

All of the turbocharger components have the potential to failure and cause problems to the engine operation. Additional parts means that there are more components to be diagnosed if a problem occurs.

Turbo lag is a common misunderstood term. Many people think that turbocharger lag is the minimum engine revolutions or RPMs that is needed in order to produce required boost pressure. However, that kind of situation should be called the boost threshold. Boost threshold is a condition where the compressor turbine starts to spin at the required speed. It is dependant on the amount and speed of air flow passing through the turbine.

Turbo lag is the time required to change speed and function effectively in response to a throttle change. So, the lag is the time that is required by the turbo charging system to respond to the change of throttle position. For example, if we add the pressure to the throttle pedal in order to accelerate, the engine will take some time before responding to the throttle input to produce higher RPM more power. The lag is not normally experienced in a naturally aspirated engine.
