Automotive Repair Turbo  And The Basic Introduction To How A Turbo Works!

The exhaust gases from the engine pass through the turbine housing of the turbo via the turbine blades, this in turn begins to spin the turbine. On the front end of the turbo is a Compressor wheel. This is located in the compressor housing with a pipe which is fed from your air filter. As the shaft begins to spin, so does the compressor wheel. This begins to draw air in from the intake, compressing it into the compressor outlet. The outlet is then fed through the car’s intercooler and then on to the engines inlet ready for the engine cycle.

Automotive Repair Turbo Symptoms Of A Blown Turbo…

Before you start looking for an automotive repair turbo you should know the most common symptom would be excessive blue smoke; this is caused by the seals on the turbo shaft leaking oil into the exhaust side, or compression side of the turbo. For those of you wondering why it has an oil supply, it’s simply to lubricate the bearings on the turbo shaft.

Another symptom would be loss of power, this can be caused by a number of things, a split intake hose which would create a whistling noise (not to be confused with a whining noise), the waste gate stuck open which would cause the exhaust gas to rush straight down the exhaust manifold and not turn the turbine, therefore the compression side of the turbo is not making any boost pressure. Variable vanes sticking due to a build up of exhaust carbon in the variable vane chamber. Variable vanes operate by allowing exhaust gas to pass through them and spin the turbine, if these vanes are stuck in any way then they will not spin the turbine properly or in some cases not spin it at all, in most cases if you are experiencing loss of power the turbo will need to be taken apart.

 Automotive Repair And Recondition Turbos VS  New Turbos

Reconditioned or repaired turbos offer the same quality as new turbos the difference between a reconditioned turbo and a new turbo is the reconditioned turbo has been striped down and cleaned, then all of the moving parts replaced by new parts. The rest of the turbo parts such as the compressor housing and exhaust housing don’t normally need replaced as they rarely suffer from much wear, so when you get your reconditioned turbo it should look almost like a new turbo.

A new turbo is almost like a reconditioned turbo but the difference is the new turbo has nice new shiny housings and of course the new turbo will be twice the price of the reconditioned turbo, so your better of with a reconditioned turbo as it’s just as good as a new one.

Turbocharger Repair

  

Turbochargers and Twin Turbochargers

A “Turbocharger” is simply a gas-pressure turbine drive connected to a centrifugal air compressor, with the turbo vane and compressor impeller mounted on a shared rotating center shaft. In a turbocharged engine, hot pressurized exhaust is directed to a turbine drive typically mounted on the engines exhaust manifold, the pressure of the exiting exhaust spins the turbine drive on its way out of the exhaust manifold. The spinning pressure vane spins the air compressor which in turn creates “boost pressure”. Compressed air is measured in pounds per square inch, also known as “pounds of boost,” typically the compressed air is piped through an inner-cooler, then to the intake manifold of the engine.

The desired benefit of compressing the engines intake air is so you may add more fuel to the intake charge, the more air you can stuff into the combustion chamber the more fuel you add to maintain optimum fuel/air ratio for maximum horsepower. One major drawback of compressing air is that it heats up due to increased molecular friction during the compression process, as a result the hotter air temperatures will cause the engine to produce less horsepower.

To remedy this, you have to cool the compressed air by running it through an air cooler(inter-cooler) before it enters the combustion chamber. The “inter-cooler” is usually mounted in the lower front of the car in front of the radiator for maximum cooling efficiency.

In certain cases some people choose to employ a “twin turbo system,” the main reason for this is to reduce “turbo lag” and still provide good high end boost pressure. Lag occurs at low engine RPMs when your exhaust manifold pressure is too low and not producing enough pressure to spin the air compressor fast enough to make optimum boost.

There are two types of twin turbo systems, “Parallel and sequential,” the more common “parallel” systems employs 2 smaller diameter turbo-chargers of equal flow capacity always running at the same time, with one attached to the exhaust manifold on each bank of cylinders, more commonly used on V-style engines. Two small turbos requires less pressure and time to “spool up”(reach optimum speed/pressure) while still producing the high airflow volume and drastically reducing lag time. The other type is sequential, this system although less common also employs 2 turbochargers, only in this case one has a larger flow capacity than the other. The smaller primary turbo is first to spool up, after the smaller one spools up, it will build system pressure which will cause the secondary(large diameter) to spool up as well.
