Pressure Regulator
What Does a Fuel Pressure Regulator Do to Your Car
When you need more power in your car, you are requiring a boost in air and fuel in the engine. Most fuel-ran cars have fuel pumps. Depending on the volume of fuel injected you get the power you like ? but you will have wasted so much money on it too, since fuel isn?t at all very cheap these days.
Performance fuel regulators are gadgets that are placed between the tank and just before the injectors. These help regulate the flow of fuel and ensures that there is consistent pressure to control the gas being led to the injectors. The unit of measurement used for the pressure being regulated is pond per square inch or PSI.
Fuel pressure regulators come in different shapes and sizes but there is only one use for them ? to maintain the pressure above the intake manifold. This ensures that there is an optimum level of fuel being injected to the system. The excess fuel is restricted and returned to the tank, thus saving them for the next cycle.
This piece of equipment can be found where the fuel rail is. This fuel rail is the pipe, which holds the fuel for distribution to the injectors and cold start valve. This gadget is the last stop for the fuel as it gets pumped into the engine compartment. It is often cylindrical in shape and is made of metal.
The main job of the fuel regulator is as it name implies, to regulate the pressure in the fuel system to a standard constant of 28 psi. This varies depending on the car make. To accomplish this task, the gadget employs a diaphragm, which controls the valve. Excessive pressure in the line will open this valve up and release the fuel but will push back excess gas to the tank.
The regulator?s vacuum also helps decrease emissions as the car halts. When deceleration occurs, the vacuum opens the valve where the fuel is returned to reduce the pressure in the system. This helps prevent excessive production of hydrocarbon since there is less fuel being injected due to the low pressure.
There is a need to install a fuel pressure regulator in order to adjust fuel pressure according to any modifications you might have already done with your engine. These regulators are necessary if you have installed high flow aftermarket fuel pumps in your car.
Some adjustable fuel regulators are especially useful since it provides an automatic self-adjusting regulator and emissions controller in one. These gadgets are often very reliable.
There is an offshoot of this regulator system, which is called the Fuel Management Unit (FMU). It serves as a supplemental upgrade to the fuel system, which could increase both air and fuel flow to your car?s engine. The FMU is an adjustable or variable fuel pressure regulator that automatically gives a boost to your system. What it does it that it restricts the flow of fuel that goes back to the tank. When flow is restricted, pressure builds up. This increase in pressure will deliver more fuel with the same amount of time it takes for an ordinary fuel regulator.
