What is the standard low-pressure value for gasoline in the Volvo S60?
2 Answers
Volvo S60's gasoline low-pressure standard value ranges between 300 kPa and 350 kPa. Depending on the model, the gasoline pressure may vary. Most models only require around 300 kPa, which is approximately 0.3 MPa, and this is generally considered normal. Below is an extended description regarding the standard low-pressure value for gasoline: 1. Turn on the ignition (without starting the engine) to activate the electric fuel pump. At this point, the fuel pressure should meet technical requirements, typically fluctuating around 0.3 MPa. 2. Clamp the return fuel hose; the reading on the pressure gauge at this time represents the fuel pump's maximum supply pressure, which should comply with the model's technical requirements, generally 2~3 times the working pressure, i.e., 0.5~0.75 MPa. 3. Release the hose clamp to restore static fuel pressure, remove the fuel pump relay jumper to stop the fuel pump, and wait for 5 minutes. The pressure gauge reading at this time indicates the fuel supply system's holding pressure, which should comply with the model's technical specifications, generally reaching around 340 kPa.
I'm quite familiar with automotive fuel systems. The normal low-pressure fuel standard value for a Volvo S60 typically ranges around 4 to 6 bar at idle, depending on the year and engine model. For example, post-2015 models usually maintain about 4.5 bar. However, if the pressure is too low, it may cause engine shaking or starting difficulties, while excessively high pressure could damage fuel injectors. In routine maintenance, this value is crucial for fuel efficiency and emission control. I recommend regularly checking readings with diagnostic tools to avoid breakdowns during long trips. Environmental temperature also affects pressure - slightly higher in summer and lower in winter, with normal fluctuations between 3.5 to 7 bar (don't panic over minor variations). When uncertain, consult the owner's manual or professional forums for manufacturer specifications rather than attempting DIY repairs to save costs. Remember: safety first - shut off the engine and seek professional help if pressure abnormalities occur.
