What is the mechanism of a turbocharger?

What is the mechanism of a turbocharger?

An air pump that reuses the energy from engine exhaust gases that are emitted unnecessarily.

A turbocharger is a type of air pump that reuses the energy from engine exhaust gases that would normally be wasted. The exhaust gases first drive the turbine wheel assembly. This part is connected to the compressor wheel. As the connected compressor wheel rotates, it is possible to send a large amount of air into the engine's combustion chamber in a compressed state. Since the compressed air has increased density, it allows for more fuel to be injected, which is why a turbocharged engine can produce greater horsepower than a non-turbo engine of the same size. *For more details, please refer to the PDF document or feel free to contact us.*

[Useful Information] Examples of Turbocharger Failures

[Useful Information] Examples of Turbocharger Failures

Here is a summary of common troubles related to turbochargers! Issues such as foreign substances in the oil, engine compression problems, and blow-by failures.

Turbocharger failures are mostly caused by external factors. Despite failures caused by reasons other than the turbocharger, if the abnormalities are not detected and there are no countermeasures, replacing the unit will lead to similar failures. 【Examples of Turbo Failure Causes】 ■ Troubles related to lubricating oil ■ Damage due to foreign object intrusion on the intake or exhaust side ■ Contamination of lubricating oil with foreign substances ■ Poor engine compression and blow-by ■ Excessive rise in engine exhaust temperature ■ Troubles due to installation errors ■ Malfunction of the actuator 【About Us】 At Showa Co., Ltd., we provide "rebuilt technology" that utilizes specialized regeneration techniques as an authorized dealer for turbo manufacturers worldwide, regenerating mechanical parts to a quality comparable to new. We cater to a wide range of needs from light vehicles to imported cars, trucks, construction machinery, and ships. *If you have any issues with turbos or injection pumps, please consult us first!

Is balancing the turbocharger important?

Is balancing the turbocharger important?

In the worst case, it can lead to damage issues! Things you want to know about turbo balance.

The turbo of a turbocharger spins at high speeds of about 100,000 to 250,000 RPM. What happens if the balance is off? Unbalanced tires cause vibrations and result in a very uncomfortable ride. In the case of a turbo, if it is unbalanced, not only will it fail to perform at its best, but in the worst case, it can lead to damage issues. Our company uses two types of balance testers to perform balance corrections with higher precision than new ones. Please feel free to consult us. *For more details, please refer to the PDF document or feel free to contact us.

Continental Corporation aluminum alloy turbocharger

Continental Corporation aluminum alloy turbocharger

[Continental Corporation - Domestic Authorized Dealer] Uses aluminum for the turbine housing. Not only reduces weight but also suppresses oil sludge formation!

Continental, well-known for its tires, also produces turbochargers as OEM. Here, we would like to introduce the features of the "Continental Turbocharger." Our company signed a contract with Continental in 2020 as the after-sales agent in Japan and is recognized as an official distributor in the country. The exhaust side housing, which is typically made of heat-resistant alloy (with iron as the main component), is made of "aluminum" in the Continental turbocharger model. Although the exhaust temperature exceeds 700 degrees, using a water-cooling system resolves the thermal issues associated with aluminum. Additionally, it allows for the cooling water to be heated in a short time. ★ We also provide OEM turbochargers for small gasoline vehicles, including BMW, AUDI, and FORD. 【Product Features】 ■ Cost reduction ■ Weight reduction ■ Accelerates the rise in engine oil and cooling water temperature ■ Suppresses oil sludge generation *For more details, please refer to the PDF materials or feel free to contact us.
