What is a Fuel Pressure Regulator and how does it work?
A fuel pressure regulator is used to maintain a steady fuel supply, even during dramatic changes in fuel demand. The fuel pressure regulator diaphragm has two sides/chambers, one side is under pressure from the fuel rail and the other side is subject to vacuum/boost pressure from the inlet tract – between the throttle plate and the inlet port. The ideal ratio is a 1:1 ratio. The fuel pressure regulator regulates the fuel pressure against the air pressure/boost, this leads to that the fuel injector can maintain the perfect ratio between fuel and boost.
The fuel pressure regulator consists of a diaphragm that controls the bypass valve “ball seat” and as the picture below illustrates it can open and close in order to adjust itself for a steady fuel delivery.
When pressure (boost) is applied to the top of the regulator, the diaphragm, which is attached to the bypass valve, a spring forces the diaphragm down and reduces the amount of excess fuel, this makes the fuel pumps work harder while the fuel pressure increases linearly towards the increasing boost pressure from the intake manifold.
