Material: 6063-T6 Aluminum alloy Color: red, blue, red and black, all black, blue, black, red, red, silver, purple and black As the internal diaphragm is made of special material, it plays a certain buffering role on the average fuel pressure, making the oil pressure more stable. In the case of not changing the computer oil supply mode, increase the appropriate amount of fuel injection, save costs. It can increase the pressure of the nozzle to about 3.0-5.5kg (the usual pressure is about 3.0kg, and it can be adjusted to about 3.7kg), which is a comfortable pressure for the nozzle. Fuel supercharging is mainly to increase the nozzle pressure, so that the fuel spray into the fog, fuel mixing ratio to improve, combustion more fully, so as to improve the power, is the real sense of fuel and power is proportional to! The main function of the fuel supercharger is to improve the fuel pressure of the electronic injection engine. After the fuel pressure is increased, the fuel ejected from the injection nozzle will be more fine, atomized and burned more completely. Thus, the amount of fuel injection can be increased (about 5-10%) without changing the oil supply mode. Achieve the lifting power, increase the torque effect. It is also one of the least expensive and most effective modification products in the oil circuit. If the car is starting up and going up a hill, and you feel that it\'s not strong enough, and you don\'t have enough power, then you don\'t have enough torque. At this time, suggest you add a fuel supercharger. The working principle and the original car fuel line pressure control valve, just converted the supercharger is a kind of can adjust the pressure control valve, generally speaking from experience, after install the control valve, according to the experience and the use of scientific principle, can be the engine fuel pressure in this device under the control, adjustment to 2 kg - 3.7 kg.
