What is the normal turbo boost pressure?

For ordinary family cars, the normal turbo boost pressure ranges between 1.2bar and 1.5bar. The maintenance methods for turbocharged engines are as follows: 1. Use high-grade synthetic oil: Since the combustion temperature and working pressure inside a turbocharged engine are significantly higher than those of a naturally aspirated engine during operation, turbocharged engines have higher requirements for lubrication and cooling. To ensure normal engine operation under more demanding working conditions, conventional mineral oil can no longer meet the requirements, and synthetic oil with better lubrication and cleaning capabilities must be used. Synthetic oil far surpasses mineral oil in terms of lubrication, cleaning, and anti-friction capabilities, and it also forms a lubricating film quickly, with high strength and good stability. Therefore, turbocharged models must use synthetic oil, preferably full synthetic oil. 2. Direct injection engines require the use of fuel injector cleaner: Direct injection sprays fuel directly into the cylinder, where it mixes with air. The ECU can precisely control the amount and timing of fuel injection based on the amount of air intake, ensuring that the air-fuel mixture burns more completely, thereby reducing fuel consumption and improving engine performance. However, because the fuel injectors in direct injection engines are placed directly inside the cylinders, they are prone to gum and carbon deposits. It is generally recommended to regularly add fuel injector cleaner to gasoline to clean the injectors. If the gum and carbon deposits on the injectors are severe, they need to be removed for cleaning. 3. Regular inspection: Due to the numerous components in a turbocharged engine, it is important to frequently check for unusual noises or vibrations in the turbocharger, and to inspect the lubrication pipes and joints for leaks. Check whether there is residual oil at the turbocharger exhaust outlet or oil on the walls of the compressor intake pipe. Oil consumption in turbocharged engines is not a common issue, but as a precaution, it is recommended that owners regularly pull out the engine oil dipstick to check oil consumption and ensure the oil level is within the normal range. If visible oil consumption is detected, it is best to visit a repair station for inspection as soon as possible.
