What is the normal pressure range for a supercharger?
2 Answers
Supercharger pressure is normal between 1.2 to 1.5 bar. A supercharger is a device used in piston-type aircraft engines to increase the intake pressure of the cylinders. It includes: exhaust turbochargers, mechanical turbochargers, and electrically assisted turbochargers. Precautions for using a supercharger are: 1. Do not rev the engine aggressively after startup; 2. Do not shut down the engine immediately after prolonged high-speed operation; 3. Maintain cleanliness when disassembling the supercharger. The working principle of an engine supercharger is: the exhaust gases from the engine cylinders drive the turbine wheel, which in turn drives the compressor wheel to pressurize the air filtered by the air cleaner and deliver it into the cylinders.
Normally, the pressure range of a turbocharger is around 0.5 to 1.0 bar, depending on your vehicle model, as different engines have varying design parameters. From my experience, if you drive a regular family car with a 1.5T or 2.0T engine, this range is generally safe. Too low boost pressure may result in insufficient power and sluggish acceleration, while too high pressure could damage internal engine components like the cylinder head or pistons. During checks, it's best to use a pressure gauge connected to the intake pipe for measurement. While driving, pay attention to the warning lights on the dashboard—if they illuminate, promptly troubleshoot to avoid more severe consequences. Remember, maintaining proper boost pressure is crucial for extending engine lifespan.
