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.

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!

Our company also supports three components of the common rail system: "high-pressure pump," "accumulator rail," and "injector." The high-pressure pump is responsible for pressurizing the fuel and sending it to the rail. If it fails, it cannot create the proper pressure, leading to issues such as engine starting difficulties. Some repairs may be possible, so please contact us. The accumulator rail acts like a tank that stores high-pressure fuel. Easy repairs are dangerous and generally not possible. It is common to replace it with a new one. The injector is the most critical component of the common rail system, performing the complex task of injecting fuel into the cylinder. Typically, the only option is to replace it with a new part, but we will provide suggestions using all possible methods. If you are in need, please feel free to consult with us. *For more details, please refer to the PDF materials or feel free to contact us.*

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.

• Other machine elements

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.*
