Turbocharger principle

Why supercharged?

1.Supercharged engine power can be  increased

There are ways to increase engine power:additional fuel; increasing engine displacement increased volume expansion cylinder; pressurization.

1.1.Additional fuel

Engine power associated with theconsumption of air and fuel.

However, if you add too much fuel while the engine gas volume does not increase, incomplete combustion, resulting in exhaust black smoke.

1.2.Increase in engine size, the cylinder capacity increases, increased displacement, can also increase the engine power

But a lot of the engine weight increases, more harm than good.

1.3.Supercharged engine power can be increased, but the mechanical work need to consume energy, consume some power,
The engine power increase is not obvious.

1.4.Turbocharged engine power can be increased by using exhaust energy work, do not consume other energy booster The
effect is significant.

2.Supercharger can compensate for lack of power when high altitude

Altitude oxygen content in the air when the engine cylinder is low at this time is relatively small pressurized oxygen
content can To provide more air to the cylinder there by increasing the amount of oxygen, the engine returns to normal altitudes of

 power.

3.Booster can protect the environment

Supercharger can make fuel burn more fully, thereby reducing emissions, reduce pollution and protect the environment.

Works

1 Turbine end


Turbine casing connected to the engine exhaust pipe, the exhaust gas-driven turbine housing the impeller, the turbine
wheel to drive the pressure on the impeller coaxially.

The more exhaust gas through the turbine housing, turbine wheel to turn faster, with the turbine speed increases, the
pressure impeller speed increases, so that more air through the filter into the pressure shell.

2 Compressor side


The faster the speed, the air sucked more
air into the pressure after the shell by pressing impeller, diffuser area so
that the air pressure and pressed into the engine, this process causes the air
temperature rises, sometimes more than 200 degrees.

3 Oil supply

Turbocharger using the same engine oil, oil as a lubricant and as both the cooling oil, the oil pressure into the
intermediate housing, through the floating bearing and thrust system.

Floating bearing can rotate freely floating, in order to work properly, and the intermediate floating bearing
housings and shaft should be established between the oil film. Dirty oil, into
the hole blockage will cause serious damage to the turbocharger. Part high-speed
movement generates heat, while there is heat to the turbine end in the middle
of the shell, the oil can take the heat, thereby reducing the temperature ofthe middle crust.

4 Sealing ring

In the vortex supercharger side and
pressure side has a seal ring, seal ring is the role of an effective seal to
avoid gas and air into the middle of the shell and prevent oil spills (oil on
both sides toward the middle shell penetration).

HOW TO PROLONG THE SERVICE LIFE OF YOUR
TURBO

 

We believe that our products are built to
high quality standards with pride and confidence. However it is important to
know what the factors are affecting the life of your turbocharger.

 

Analysis indicates that approximately 40%
of the troubles are due to foreign material entering either the turbine or the
compressor inlet ports. An additional 40% are due to lubrication failures. The
remaining 20% are of a miscellaneous nature.

 

Foreign materials vary from a piece of
burned or broken valve, combustion cups, casting fins of manifolds and ports,
improperly installed gasket, broken pistons, pieces of the air cleaner, pieces
of rubber or wire reinforcing from the inlet hose, nuts/bolts/washers dropped
in, etc.

 

Lubrication failures may be any one of a
number of types. Undersized or blocked oil lines are quite common .It is
essential to have an adequate supply of oil at full engine oil pressure for the
turbocharger bearings. The turbocharger runs at very high speeds and will very
quickly overheat with even a momentary failure of oil supply.

 

Failures may occur due to exhaust
temperatures encountered in excessive altitude operation. Altitude operation
will also cause the turbocharger speed to increase which may cause failures due
to over speeding and high temperatures unless the engine’s fuel system is
derated according to the manufacturer’s recommendations.

 

Extreme exhaust temperature can also be due
to reduced air supply. This can be 
caused by blocked air cleaners, collapsed hose connections, undersized
air pipes, accumulated dirt in the compressor housing due to poor air cleaning
system, leaking gaskets or connections on either the either intake or exhaust
system,etc.

 

Thermal expansion of any parts, excessively
heavy piping that is only supported by the turbocharger, mountings that are not
sufficiently rigid to prevent vibration, if not properly installed, will
produce very high loads on the turbocharger. This can result in distortions
which can cause the compressor and turbine wheels to rub on their respective housings.

 

In conclusion it can be stated that very
few turbocharger failures would occur if no foreign material were permitted to
enter either the turbine or the compressor, if the turbocharger was always
supplied with an adequate amount of clean oil, and if precautions were taken to
prevent excessive exhaust temperatures.

 

 

 

CHECKLIST

Before fitting the turbocharger, the
following must be done:

 

1.Inspect and clear, if necessary, the
intake and exhaust systems leading to and from the turbocharger to ensure
absence of foreign material. This includes burrs and loose lining fragments. Be
thorough – even small particles can cause severe rotor damage if induced during
high speed operation.

 

2.Use new and approved gaskets at the
various air, oil and exhaust connections to the turbocharger. Liquid gasket or
sealants are not recommended, particularly for oil fittings.

 

3.Use a high temperature anti-seize compound
(such as Fel-Pro C5A) on all threaded fasteners connected to the turbocharger.

 

4.Fill the turbocharger oil inlet port to
overflowing with clean engine oil before connecting the oil feed hose to the
turbocharger.

 

When fitting the turbocharger to the
manifold and connecting the respective pipes, the following must be done:

 

1.Before connecting the oil drain hose,
crank the engine without firing until steady stream of oil flows from the drain
port.  

 

2.Operate the engine at low idle for at
least three minutes after completing the installation of any turbocharger. This
will prevent oil starvation damage to the bearing system, and will tend to
purge any residual contaminants from the bearing housing prior to unit
acceleration.
