Product Description
Compressor housing, also known as a compressor cover, is a critical component of a turbocharger or a supercharger system in internal combustion engines. Its primary function is to encase the compressor wheel and direct the flow of air into and out of the compressor. Here's a more detailed look at its role and importance:
The compressor housing encloses the rotating compressor wheel, which is driven by the exhaust gases in the case of a turbocharger, or by a belt connected to the engine in the case of a supercharger. This containment is essential for directing airflow properly and ensuring efficient compression.
It is designed to optimize the flow of air into the compressor wheel and then out towards the engine's intake manifold. The shape and internal geometry of the compressor housing are critical in reducing turbulence and maximizing the efficiency of the air compression process.
The housing helps to manage and maintain the pressure of the compressed air. It ensures that the air is compressed efficiently before it is delivered to the engine, which helps to improve engine performance by increasing the air density entering the combustion chamber.
Some compressor housings are designed with cooling features to dissipate heat generated during the compression process. This helps to maintain the integrity and performance of the turbocharger or supercharger.
The housing provides structural support to the compressor assembly and protects other engine components from potential damage due to high-speed rotational forces or failure of the compressor wheel.
In summary, the compressor housing is a vital part of the forced induction system in internal combustion engines, contributing to better engine performance, efficiency, and reliability.

FAQ
A compressor that has both the motor and the compressor in one housing is commonly referred to as a hermetic compressor. Here are the key details about hermetic compressors:
In a hermetic compressor, the motor and the compressor are sealed within a single airtight housing. This housing is typically welded shut, making the internal components inaccessible for maintenance.
Hermetic compressors are widely used in refrigeration and air conditioning systems. They are particularly common in household refrigerators, freezers, and small air conditioning units due to their compact and efficient design.
Reduced Leakage:
The sealed design minimizes the risk of refrigerant leakage, which is critical for maintaining system efficiency and environmental safety.
Quiet Operation:
The enclosed housing helps dampen noise, making hermetic compressors quieter compared to other types of compressors.
Compact Size:
Integrating the motor and compressor into a single unit allows for a more compact and space-saving design.
Maintenance:
Since the housing is sealed, hermetic compressors are not serviceable. If a component fails, the entire unit typically needs to be replaced.
Cost:
While the initial cost might be lower, the inability to repair can lead to higher replacement costs over the long term.
Semi-Hermetic Compressors:
These are similar to hermetic compressors but are designed to be partially opened for repairs and maintenance. They offer a balance between serviceability and the reduced risk of leakage.
Hermetic compressors are valued for their reliability, efficiency, and suitability for applications where maintenance accessibility is less critical.
The type of compressors that contain both the compressor and motor together inside a welded steel housing are known as hermetic compressors. These compressors are characterized by their fully sealed construction, which encapsulates the motor and compressor in a single, airtight steel housing. This design has several notable features and benefits:
The welded steel housing prevents refrigerant leaks and protects the internal components from contamination and external damage.
Hermetic compressors are frequently used in household refrigerators, freezers, air conditioners, and small commercial refrigeration systems due to their reliability and compact design.
The sealed housing helps to dampen operational noise, making these compressors quieter compared to other types.
The integrated design allows for efficient operation, as the motor and compressor are optimized to work together within the same enclosure.
One of the primary disadvantages is that hermetic compressors are not serviceable. If a failure occurs, the entire compressor unit must be replaced rather than repaired.
Hermetic compressors are widely used in various refrigeration and air conditioning applications due to their efficient, quiet, and leak-resistant design. However, their sealed nature means they cannot be repaired if something goes wrong, requiring full replacement instead.
When the compressor and motor operate on the same shaft and are enclosed in a common casing, it is known as a hermetically sealed compressor.
A turbocharger compressor housing is a crucial component of a turbocharger system in an internal combustion engine. The turbocharger itself is a device designed to increase the efficiency and power output of an engine by forcing extra air into the combustion chamber. Here's a detailed breakdown of the compressor housing's role and function:
A turbocharger consists of three main parts:
Turbine Housing:
This is where exhaust gases from the engine spin the turbine wheel.
Compressor Housing:
This houses the compressor wheel and is responsible for compressing and directing air into the engine.
Center Housing Rotating Assembly (CHRA):
This contains the bearings and the shaft that connects the turbine and compressor wheels.
Air Intake and Compression: The compressor housing contains the compressor wheel, which is driven by the shaft connected to the turbine. As the compressor wheel spins, it draws in ambient air, compresses it, and forces it into the engine's intake manifold.
Boost Pressure: By compressing the intake air, the compressor housing helps increase the air pressure (boost pressure) delivered to the engine, allowing for more fuel to be added and therefore increasing the engine's power output.
Volute Design: The compressor housing typically has a spiral or volute design that helps to efficiently convert the high-speed, low-pressure air exiting the compressor wheel into high-pressure air for the engine intake.
Compressor housings are usually made from materials that can withstand high temperatures and pressures, such as aluminum or cast iron. The design must also be robust enough to handle the centrifugal forces generated by the rapidly spinning compressor wheel.
The efficiency and performance of the compressor housing directly affect the turbocharger's ability to improve engine performance. A well-designed compressor housing ensures optimal air flow, minimal losses, and effective pressure delivery to the engine, which are crucial for achieving the desired power gains.
Turbocharger compressor housings are used in various applications, including:
Automotive Engines: Both gasoline and diesel engines in cars and trucks.
Aerospace: Aircraft engines.
Marine: Boat and ship engines.
Industrial: Power generation and other industrial applications.
The compressor housing is a component of a turbocharger that houses the compressor wheel. It is responsible for drawing in ambient air, compressing it, and directing it into the engine’s intake manifold to increase air pressure and engine performance.
By compressing and increasing the amount of air delivered to the engine, the compressor housing helps to significantly enhance engine power and efficiency. More compressed air allows for more fuel to be burned, resulting in greater power output.
Compressor housings are typically made from durable materials that can withstand high temperatures and pressures, such as aluminum or cast iron. These materials ensure the housing can handle the operational stresses of a turbocharged engine.
The volute design, which is a spiral-shaped casing, helps efficiently convert the high-speed, low-pressure air exiting the compressor wheel into high-pressure air. This design optimizes air flow and pressure delivery to the engine.
Depending on the extent of the damage, some compressor housings can be repaired. However, significant damage may require a complete replacement to ensure the turbocharger operates safely and efficiently.
Symptoms of a faulty compressor housing include unusual noises, reduced engine performance, excessive smoke from the exhaust, and oil leaks. Regular inspections and maintenance can help detect issues early.
No, compressor housings come in various sizes and designs to match different engine specifications and performance requirements. The size and design are chosen based on the desired boost pressure and engine capacity.
The compressor housing is on the intake side of the turbocharger and deals with air compression and delivery to the engine. The turbine housing, on the other hand, is on the exhaust side and houses the turbine wheel that is driven by exhaust gases to power the compressor wheel.
It is recommended to inspect the compressor housing during regular engine maintenance or if you notice any symptoms of turbocharger issues. Regular inspections help prevent potential failures and maintain optimal performance.
Yes, aftermarket compressor housings can be designed to enhance turbocharger performance by improving airflow efficiency and increasing boost pressure. However, it is important to ensure that the aftermarket part is compatible with your specific turbocharger and engine.
