A world turbocharger is a centrifugal supercharger powered by a turbine that is driven by exhaust gas flow. It is an exhaust-driven compressor that increases the mass flow of air into the engine to improve performance. The turbocharger compresses ambient air to a higher pressure and temperature before sending it to the intake manifold, improving the engine's combustion process and overall efficiency. There are numerous types of turbochargers, each designed for specific applications and use cases. The following are the most common types of world turbochargers:
Single Turbocharger
Single turbochargers are the most commonly used types of turbochargers. They are used in most factory-built vehicles. Single turbochargers are simple and easy to install, making them affordable for many people. This turbocharger is small and compact, making it ideal for use in petrol engines. Single turbochargers have low turbo lag, which allows them to spool quickly and produce more power at lower RPM.
Variable Geometry Turbocharger
Variable geometry turbochargers are designed to improve performance in diesel engines. They are designed with adjustable blades that change position depending on the engine's RPM. This allows the VGT to optimize boost pressure across the entire RPM range. These turbochargers have better spool times and can generate boost much earlier in the power band. VGTs are more complex than traditional turbochargers and require careful maintenance to ensure optimal performance.
Twin Turbocharger
Twin turbochargers combine two turbochargers to create a more powerful boost. There are two main types of twin turbochargers: parallel and sequential twin turbochargers. Parallel twin turbochargers use two identical turbochargers, with each turbocharger boosting air into half of the engine's cylinders. In contrast, sequential twin turbochargers use a small turbocharger and a large turbocharger. The small turbocharger spools quickly and generates boost at lower RPMs, while the larger turbocharger kicks in at higher RPMs to provide a more powerful boost.
Super Turbocharger
Super turbochargers combine the features of a supercharger and a turbocharger into one unit. This hybrid improves engine performance and efficiency. The super turbocharger forces more air into the combustion chamber, resulting in a significant power increase. Super turbochargers are relatively new and are becoming more popular in high-performance vehicles.
Electric Turbocharger
Electric turbochargers are becoming increasingly popular in modern electric and hybrid vehicles. These turbochargers use electric motors to spin the turbine, reducing turbo lag and improving responsiveness. Electric turbochargers can be integrated into the vehicle's battery system, providing a boost on demand.
The specifications of the turbocharger will depend on the type of car and the model. Here are some general specifications of turbochargers:
Compressor Wheel:
The compressor wheel is the vital part of the turbocharger that determines how much air is compressed into the engine. The compressor wheel is made from aluminum and has a size ranging from 30 to 100 mm or more.
Turbine Wheel:
The turbine wheel is an equally important part as the compressor wheel because it is connected to the exhaust gases. The turbine wheel also ranges from 30 to 100 mm or more, but it is made from cast iron or steel.
Bearing System:
The bearing system is what connects the wheels to the body of the turbocharger to spin smoothly. It is made from hardened steel and has a variety of bearing types, such as journal and ball bearings. The type of bearing affects the cost of the turbocharger.
Housing:
The housing is what encloses and protects all the parts of the turbocharger. The housing is made from cast iron or aluminum and is designed to minimize heat loss and airflow resistance. The housing also contains the wastegate and actuator.
Wastegate:
The wastegate controls the amount of exhaust gas flowing to the turbine wheel to prevent over-speeding. The wastegate can be internal or external, depending on the design of the turbocharger.
Maintaining turbochargers is very important to keep them in good condition and functioning properly. Here are some important tips for maintaining the world turbocharger:
Regular Oil Changes:
It is important to change the engine oil regularly. This is because the turbo relies on engine oil for lubrication and cooling. It is advisable to change the oil every 5,000 miles or as recommended by the car manufacturer.
Use Quality Oil:
Always use high-quality engine oil with the right viscosity for the car. Low-quality oil can damage the turbocharger by clogging the oil passages or causing overheating.
Allow Cooldown:
After hard driving or highway driving, always allow the engine to idle for a minute or two before turning off the ignition. This allows the turbo to cool down and prevents heat soak into the oil.
Inspect Intercooler Hoses:
Check the intercooler hoses for any signs of leaks, cracks, or damage. Leaking hoses can reduce boost pressure and affect engine performance. Replace any damaged hoses immediately.
Air Filter Maintenance:
Clean or replace the air filter regularly to ensure proper airflow to the turbo. A clogged air filter can restrict airflow and reduce turbo efficiency.
Regular Turbo Inspection:
Schedule a professional inspection of the turbocharger every 30,000 miles or as recommended. A qualified mechanic can check for any signs of wear, play in the shaft, or oil leaks and perform necessary repairs.
Avoid Excessive Load:
Do not overload the vehicle or tow more than the recommended towing capacity. Excessive load can put extra strain on the turbo and lead to premature failure.
The following factors should be considered when selecting a turbocharger for a given application:
Engine Size
The world turbochargers to be selected should be based on the size of the engine. Larger engines are better suited for larger turbochargers, while smaller engines work better with smaller turbochargers.
Driving Style
For those who prefer aggressive driving, a larger turbocharger may be beneficial. A smaller turbocharger may be sufficient for those who engage in more relaxed driving.
Type of Fuel
The kind of fuel used can also influence the choice of turbocharger. For example, a turbocharger designed for high-octane fuel may be required to get the most out of the fuel in racing settings.
Application
Different applications such as racing, off-road, or street use will determine the kind of turbocharger to be selected based on the design and specifications.
Replacing a turbo isn't as easy as it may seem. However, with the right tools and technical know-how, it can be done. Here are the steps to follow when replacing a turbocharger:
Tools needed:
Step-by-step guide
Remove the old turbocharger
Drain the oil and coolant from the vehicle. Then, disconnect the intake and exhaust pipes from the turbo. After that, disconnect the oil feed and drain pipes and the coolant lines. The turbocharger is held in place with bolts that attach it to the manifold. One should loosen the bolts with a socket and ratchet and then remove the turbo from the mounting.
Prepare the new turbocharger
One should compare the old and new turbochargers to ensure they are the same. Then, apply new gaskets and seals to the new turbo.
Install the new turbocharger
First, position the new turbocharger onto the manifold and secure it with bolts. Then, reconnect the oil feed and drain pipes and coolant lines. After that, reconnect the intake pipe and exhaust pipe and ensure there are no leaks. Finally, fill the engine with new oil and coolant.
Q1. Are larger turbochargers always better?
A1. Larger turbochargers are not necessarily better. While they can produce more power at higher RPMs, they may also cause turbo lag and be less efficient at lower RPMs. The optimal size depends on the engine's characteristics and the driver's performance requirements.
Q2. Can any engine be turbocharged?
A2. In principle, any engine can be turbocharged. However, the process requires careful consideration of the engine's design, internal components, and exhaust flow. Additionally, engines not originally designed for turbocharging may require further modifications to handle the increased airflow and pressure.
Q3. What is turbo lag?
A3. Turbo lag is the delay in throttle response caused by the inertia of the turbine and compressor wheels in a turbocharger. When the throttle is pressed, there is a brief lag before the turbo reaches its optimal speed, and boost pressure increases, leading to a delay in power delivery.
Q4. How can turbo lag be reduced?
A4. Turbo lag can be reduced by using smaller turbochargers, twin-scroll turbochargers, or variable geometry turbochargers. Electronic wastegates, boost controllers, and improved engine tuning can also help. Additionally, lighter turbine and compressor wheels can decrease inertia and minimize lag.
Q5. Is regular maintenance important for turbocharged engines?
A5. Yes, maintaining turbocharged engines is crucial. Turbos rely on regular oil changes and clean oil flow for lubrication and cooling. Follow the manufacturer's maintenance schedule, use high-quality oil, and ensure proper engine care to maintain turbo performance and longevity.
