To the world's vehicle industry, turbo charging is not a new word. It has been hundreds of years since the concept of engine turbocharger was born. In the year of 1905, Dr Alfred J Buchi, the chief engineer of Sulzer brother Development Company first put forward the concept of turbo charging, and on November 16th the same year, the German patent office granted him of the patent. This is the mark of the birth of turbo charging technology. Buchi is regarded as the founder of turbo charging as well.

The principles of engine turbocharger are simple. But in fact, it is complicated and precision which needs both close fit of the inner parts and of the turbocharger and the engine.

Turbocharger works as an air pump. The impeller on one side of the turbocharger is driven by the exhaust gas from the engine. As it is rotating faster, the impeller on the other side synchronously speeds up, which increases the air inflow in the combustor. As you will understand, the air becomes extremely hot as it is compressed, so cool down is needed before it enters the combustion chamber, which is usually called inter cooler.

In 1912, the world's first turbocharger driven by exhaust gas was born. But at the very beginning, this technology was not applied to vehicle industry but to shipping and aviation area.

People at that time didn't completely realize the potential of turbocharger until the year 1938 when the first super charged truck engine hit the market. From now on, the vehicle super charge technology gradually becomes mature.

In 1961, kkk turbochargers were tentatively installed on sedan cars, firstly on Oldsmobile F85, which hit the market in 1962. Turbocharged Oldsmobile Jetfire 3.5 Liter V8 engine can supply 215 horses, while non-charged engines supplied at most 185 horses. But the instantly produced enormous pressure and heat that affected the using effect.

For sedan cars, there's a turning point of engine turbocharger in 1970s. Turbocharged Porsche911 hit the market in 1975. Swedish company Saab Automobile AB was the first manufacturer that successfully applied turbocharger on automobile products in large amounts. In 1977, Saab 99 spread the turbocharger technology even further, which enabled the 2 Liter engine as powerful as 3 Liter engine. The sales volume of the turbocharged Saab 99 cars went up to 590 thousand, which showed that the market requirement is definite. Generally, the insiders consider that Saab's application of engine turbo charging makes this technology mature and announces the birth of a new era. Turbocharger technology rewrites the traditional concept of displacement determines power.

In the long history of turbocharger's invention and development for nearly a century, Garret Company plays a vital role. Today, it is the biggest kkk turbocharger in the world with the daily production amount of 30 thousand turbochargers. The cooperative companies of Garrett turbochargers include Audi, BMW, Daimler-Benz, Ford, Chrysler, Renault, Saab and Volkswagen.

In the product series of garrett turbochargers, the most famous item would be ball bearing turbo series. It has been proved on the top level of branded value. Ball bearing can be listed as the popular turbocharger bearing technology in the world. In such product design, the central axis and the middle gearing bottom are surrounded by a ring of metal balls, which assist the rotation. The advantage of such Garrett turbocharger is with smaller resistance from rotating, so the turbocharger delay can be shortened. Therefore, it can endure quicker rotating speed, and the central rotation's balance effect can be nearly perfect. However, its weakness is on the expensive price on ball gearing turbocharger. Additionally, too small turbocharger's lubricate oil entry would make its durability poorer compared with floating gearing. But, Garrett turbocharger's quality has passed the strict tests in many world-class championships. It would not meet problem on durability in normal condition.

Introduction of Garrett turbocharger's product classifications

There are so many item series in Garrett turbocharger product family. The most basic classified items are based on different labels of GT25, GT28, GT3, GT4 and GT5 to tell the sizes. The wind entry amount of GT25 is smaller than GT5. And then, such Garrett turbochargers would be classified as per A/R level with Trim sectional division. Besides, Garrett turbochargers also own the hybrid turbo designs like GT3 with GT4.

Commonly, the recent Garrett turbocharger designs have replaced original T series by GT series with the label of “GTXXYYZZ”. In this label, “XX” stands for the max diameter of related turbocharger's turbine impeller. For instance, GT2860RS means such Garrett turbocharger uses the turbine impeller with the max diameter of 53.85mm. “YY” stands for the largest diameter of compressor impeller. For instance, GT2860RS means that it applies the compressor impeller with the max diameter of 60mm. And, GT4202 means its largest diameter of compressor impeller is 102mm. “ZZ” stands for the special device deployment. “R” in GT2860RS stands for round-ball gearing, and “S” stands for the different compressor impeller with the same turbine impeller design. Such design can be used as hybrid turbo.

The Attribute of turbocharger

Turbo charging is really a technologies that air-compressor is driven by the waste gas produced from Internal Combustion Engine, becoming comparable using the function of Super-charger, each of which can boost the air mass flow accessing into Internal Combustion Motor or boiler as a result enhancing machinery performance. It's quite often utilized for car motor. Turbocharger can effortlessly improve the horsepower output of Internal Combustion Motor, utilizing the rate of heat and movement of waste gas discharged.

Turbocharger can enhance widely the power and torque of engine without ever-increasing the engine emission, which happens to be its fantastic benefit. Most often, the ability and torque of motor would be increased 20%-30% after putting in turbocharger. The weakness of turbocharger is turbo-lag to the sudden variation of accelerator caused by inertia of impeller, creating motor delay increasing or decreasing output energy, which may make the vehicles accelerating promptly and overtaking seems to be suspended all of a sudden.

Compared with Aspirated Motor, the engine with turbocharger could improve the optimum power with 30%-40%, even more. Especially in the substantial altitude area with thin air, it would be more potent. Besides this, it nonetheless has lower torque breaking point and wider torque than aspirated motor. These traits allow the automobile speed up quickly and be having a great motive power.

As a outcome, below the help of turbocharger, displacement automobiles could possess the motive power matching the substantial displacement ones whilst decreasing 10%-20% CO2 discharging, which contributes a lot to environment protection. Then, whenever you generate steadily, it is unlikely to consume more fuel compared to same displacement car with out turbocharger. Therefore, turbocharger will probably be a improvement direction for additional automobile power.

The Components of Turbocharger

Turbocharger consists of pump impeller, turbine along with control elements. Pump impeller and turbine are linked by an axis named rotor. The waste gasoline exhausted by motor drives pump impeller which drives turbine spinning. The spinning turbine would pressurize the air inlet system. The running temperature for supercharger is rather substantial on account of becoming set up in the exhaust aspect of motor. Plus to this, the rotate speed with the rotor is incredibly high when it's operating, almost a few hundred thousand turns for each moment. Obviously, the regular mechanical needle and ball bearing can't bear such substantial rotation pace and temperature, as a result, turbocharger normally uses the complete suspension bear, lubricating with engine oil and cooling with cooling liquid. Formerly, garrett turbocharger was mostly used in diesel motor. Nevertheless, nowadays, it's also far and widely applied to oil motor.
