Avoid Flooring the Accelerator at Startup Turbochargers rely on engine oil for cooling, and during cold starts, the oil’s flowability is poor. If the turbocharger operates at high speeds during this time, it can experience significant wear. It is advisable to let the engine idle for two to three minutes until the oil can provide sufficient lubrication before revving the engine, thereby extending the lifespan of the turbocharger. This is particularly important in winter. Avoid Engine Braking in Manual Turbocharged Cars Engine braking refers to using a higher gear than necessary while driving. F ..read more

Currently, the main materials used for turbocharger housing are cast iron and cast steel, with six specific materials: Cast Iron Materials Turbocharger Housing Gray Cast Iron: Contains alloying elements such as Cr, Ni, Si, which improve high-temperature fatigue performance and oxidation resistance. It operates at temperatures below 500°C. Gray cast iron is commonly used in turbocharger housings, cylinder blocks, cylinder heads, and gearbox bodies in automobiles. Ductile Iron: Also known as nodular cast iron, it controls the amount of pearlite in the iron matrix, reducing internal stress in t ..read more
