Turbochargers Technology, and How The Turbo Work
This article first presents the basics of turbocharger operation, and then explores some of the current thinking in turbo-supercharger technology as applied to competition engines.
A significant difference between a turbocharged diesel engine and a traditional naturally aspirated gasoline engine is that the air entering a diesel engine is compressed before the fuel is injected. This is where the turbocharger is critical to the power output and efficiency of the diesel engine. It is the job of the turbocharger to compress more air flowing into the engine’s cylinder. When air is compressed the oxygen molecules are packed closer together. This increase in air means that more fuel can be added for the same size naturally aspirated engine. This generates increased mechanical power and overall efficiency improvement of the combustion process. Therefore, the engine size can be reduced for a turbocharged engine leading to better packaging, weight saving benefits and overall improved fuel economy.
Although turbocharging is a relatively simple concept, the turbocharger is critical to the operation of the diesel engine and therefore requires a highly engineered component. Our extensive experience in turbocharging technology and knowledge of engines combines for world-class design and manufacture of Holset Turbochargers, renowned for their durability, high standard of safety, and reliable performance that engines demand.
How does a turbocharger work?
A turbocharger is made up of two main sections: the turbine and the compressor. The turbine consists of the (1) turbine wheel and the (2) turbine housing. It is the job of the turbine housing to guide the (3) exhaust gas into the turbine wheel. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an (4) exhaust outlet area.
(1) The turbine wheel
(2) The turbine housing
(3) Exhaust gas
(4) Exhaust outlet area
(5) The compressor wheel
(6) The compressor housing
(7) Forged steel shaft
(8) Compressed air
The compressor also consists of two parts: the (5) compressor wheel and the (6) compressor housing. The compressor’s mode of action is opposite that of the turbine. The compressor wheel is attached to the turbine by a (7) forged steel shaft, and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and compresses it. The compressor housing then converts the high-velocity, low-pressure air stream into a high-pressure, low-velocity air stream through a process called diffusion. The (8) compressed air is pushed into the engine, allowing the engine to burn more fuel to produce more power.

What is the different between Turbocharger and Supercharger
There is quite a bit of terminology when it comes to automobile parts, and a person can get very easily confused. Some of the things that are bantered about may sound very appealing, but may not be what a car buyer wants in his or her vehicle. Understanding differences between various components helps to make a better decision. Superchargers and turbochargers are mentioned almost in the same breath by many people in the auto industry. There is definitely a difference between the two of them.
Let’s start at the beginning; both turbocharging and supercharging are force induction systems – that is they force the air into the engine at a much higher pressure than the naturally aspirated systems.
Forcing more air into the combustion chamber allows the engine to burn more fuel during its power stroke and consequently produce more energy. Both superchargers and turbochargers therefore have the same goal – producing more power, the difference lies in how they go about it.
Differences
The biggest and the most obvious difference between the two systems is where they derive their power from. Superchargers are powered by the engine’s crankshaft while turbochargers get their power from the engine’s exhaust gases.
Because turbochargers are using exhaust gases expelled by the engine they do not need to use any of the engine’s existing power to operate. This is in a stark contrast to superchargers that use a portion of the engine’s power output to perform their duties.
In deciding on which is better will depend on the vehicle itself. The reason why turbochargers are used most commonly in Europe is because the engines are small and four cylinders are standard. Superchargers can deliver their boost at lower RPMs then a turbocharger, whereas the turbocharger works best at high engine speeds.Turbochargers are quieter and superchargers are more reliable. Superchargers are easier to maintain than the complex turbocharger.
The arguments can go on back and forth. It would be great if a supercharger was in the car so that the boost could occur at low RPMs, while a turbocharger would put considerable power at a higher rotation. Volkswagen has attempted that with a twin charger engine. Besides being very expensive, the twin charger engine also only operates with premium gasoline. Determining which is better comes down to the make of the car itself. Incidentally, both are just about the same in price so money is not an issue. A regular car would do better with a supercharger. These are easier to install and tune-ups are not as difficult. The Turbo charger has its real niche in more specialized markets. It is considered more efficient overall than a supercharger. The consumer is left with deciding personally the type of car to own at from that point installing the correct forced induction system to add more power to the drive.

What is Turbocharger
Turbocharger or turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine's output results because the turbine can force more air, and proportionately more fuel, into the combustion chamber than atmospheric pressure alone.
Turbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term "supercharger" is usually applied only to mechanically driven forced induction devices. The key difference between a turbocharger and a conventional supercharger is that a supercharger is mechanically driven by the engine, often through a belt connected to the crankshaft, whereas a turbocharger is powered by a turbine driven by the engine's exhaust gas. Compared to a mechanically driven supercharger, turbochargers tend to be more efficient, but less responsive. Twincharger refers to an engine with both a supercharger and a turbocharger.
Turbochargers are commonly used on truck, car, train, aircraft, and construction equipment engines. They are most often used with Otto cycle and Diesel cycle internal combustion engines. They have also been found useful in automotive fuel cells.
