How to clean the injectors

When you need to clean the need for specific choices - how much fuel injection control: the same type of EFI car, the gasoline pump pressure is constant, regardless of the size of the throttle opening, as long as the fuel pressure regulator after the adjustment of the fuel pressure regulator, the pressure of the injector nozzle is always constant. Injector nozzle and fuel pump and fuel pressure regulator strictly supporting the use of only the design of the pressure, the injector nozzle in order to achieve the best atomization effect, the pressure is lower than the design pressure, the spray oil is not foggy, columnar, not suitable for mixing with the air; pressure is too large, the spray oil is conical shape, but also is not easy to mix, and the power of the spray is too large, a lot of fuel directly on the wall of the pipe, which directly affects the mixture ratio of Parameters.

Whether accelerating or idling, the pressure should be constant. Different models of pressure also varies (some friends mentioned a few gears of the cleaner selection, in fact, for different models of pressure selection, not acceleration and idling pressure is different, the wrong choice of injection pressure, the injector nozzle atomization is poor). The amount of fuel injection depends on the length of the injection time. Injectors are divided into two types, voltage-driven and current-driven, according to the different control methods of the electromagnetic coil. Voltage type is also divided into low-resistance and high-resistance, high-resistance can be connected to 12V electricity, low-resistance can only be connected to a low voltage, wrongly connected to 12V for a long time will burn the coil. When injecting oil, the computer provides a constant voltage, for example, 12V, immediately become 0V when the oil cut off, this change is instantaneous, like a computer language inside the 0 and 1 a concept, there is no 0.5 in the middle. In other words, this is a pulsating DC signal, not what the alternating current and other such terms. What is the concept of alternating current? Positive and negative interlacing is called alternating current. It seems that in a car, except for the part before the generator rectifier, there is basically no contact with alternating current. When the injector is clogged, the injection is not smooth, or the injector gap has carbon and adhesive material, can not reach the designed injection volume or atomization effect, only need to clean.
