What causes high diesel rail pressure?

What causes high diesel rail pressure?

As we discussed, high fuel pressure means that the air to fuel ratio is off-kilter. The causes for this imbalance of fuel pressure typically include either a bad fuel regulator or a clogged return line.

What is a high pressure common rail fuel system?

Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Common rail injection is widely used in diesel engines.

What is the main function of the high pressure rail on a common rail diesel engine?

The high-pressure rail binds the pump and injectors together as the central hydraulic component. It stores the compressed fuel and supplies this to the injectors. Pressure pulses occur in the high-pressure rail as a result of the injection process. The stored high-pressure volume reduces these to a minimum.

How much fuel pressure does a common rail diesel have?

Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.

Is Common Rail Diesel better?

Studies have shown that vehicles with a common rail diesel engine will produce 25% more power than a traditional diesel engine. This means the overall performance of the diesel engine will be improved.

Can you pump a common rail?

You can’t p pump a common rail. been done many times… but, once you’ve ppumped it, it’s no longer a common rail.

Are Common Rail engines good?

The common rail diesel engine allows for better emission control and consumption of fuel and power. In other words, common rail diesel engines can deliver more power to the vehicle while consuming less fuel and producing fewer emissions.
