Stationary turbocharger

for diesel engines

A turbocharger system is a green product that is both energy-efficient and environmentally friendly. Compared to a naturally aspirated engine system, it brings many advantages such as increased engine horsepower, reduced air pollution, reduced noise pollution and better high-altitude performance. Turbochargers work in high temperature environments. For diesel engines the operating temperature is normally 600 degrees Celsius. For petrol engines the operating temperature is between 800 and 900 degrees Celsius. The temperature can reach as high as 900 to 950 degrees Celsius for engines in specialized vehicles. As the expectation for engine performance rises, turbocharger’s operating temperature is likely to get even higher in the future. Because of its highly specialized use, materials used for turbochargers must have the following characteristics: 1. Good high temperature oxidation resistance: Because turbochargers need to operate in constant high temperature, the oxidation resistance grade of the materials used in such conditions will directly affect the product’s life expectancy. To improve the anti-oxidation performance, super alloy is commonly used. 2. Stable microstructure: The material used should have little or no phase transformation across the temperature range of room temperature to operating temperature. Otherwise the product’s performance and life expectancy will deteriorate. Therefore, it is best to used ferrite or austenite structure as the basis material.
