The fuel injector — the element of the fuel injection system of a modern car. This element is responsible for the execution of the command fuel supply into the cylinder. The brain sends a signal in microseconds that the injector receives a signal of a given duration, the injector opens, pressurized fuel system (fuel pump) is the fuel injection. In detail below, the atomizers are also here, at the bottom.

How it works atomizer

the Fuel injector Honda Civic, nothing but a tap. Yes, its a tap to which a voltage 9-15 volts, the coil of the electromagnet attracts the needle and the fuel, a torch, coming out of it. Atomizer it is the solenoid.

Parameters, properties and values

The fuel system of most vegetable Honda Civic consists of a fuel tank (45L), fuel pump, lines, connections, fuel filter, fuel rail, injectors themselves, and the \"return\" valve. The fuel tank is supplied fuel via the fuel pump wire in the fuel rail (through the filter). On the fuel rail mounted pressure regulator NR-1 (Fuel Pressure Regulator — FPR), in most cases it is enough, he was mounted on most engines, but with different system hardware. In General, fuel enters the fuel rail under pressure of about 3 Bar (3 atmospheres, 3000 mbar) if the pressure above the valve FPR NR-1 gets a surplus in the \"return\" from \"return\" fuel in the tank.
the Value injector like 190, 240 (180, 235) and so on. shown in cubic centimeters. Full marking looks like this 240 cc@3Bar, ie the atomizer for 1 minute at a pressure of 3 bar (this is the normal pressure of most pumps) throws 240 CCS of fluid.
If earlier stood the injector 190, and you want to install the 240 just replacing them, then you need to ask yourself a question. Why? 190 the injectors are not working 100% even under full engine load, that is, a margin of 15%. Yes, I agree that if you have increased or you put a blower (turbine) that the replacement of the injectors needed. And so you will get extra flow. The computer program is written that for example at 450 mbar (45кПа), injector 190 need to work for only 100 MS, replacing it with a 240 you are changing the opening time of the fuel map get an overly rich mixture. This is the same that you would ask to access big and small tap water at the same time, at the same time, where you think consumption will be more? Consider the replacement of the injectors carefully. If you do not have a dyno and / or daemon to set the type or Hondata Moates I wouldnt advise to change the nozzle.
One of the most important parameter is the resistance of the injectors, it is necessary that the resistance of the injectors the old and the new were the same. For this \"fashion\" is bought ResistorBox (30-100$). And in normal potent ceramic resistance(0.5-5$). If you do not balance the resistance with the brain, then there is an option that exits the brain on the atomizer will burn. Low impedance injectors are 2.5-3 ohms, Vanity 12th. The danger lies in the low-impedance, high-performance but of course they need more control. At 50% load 2.5 Ohm (low-resistance) atomizer on the 7th minute, when operating at 6000 engine rpm the brain starts to burn, temperature of keys (transistors) is 170-200 degrees Celsius in normal condition is 60 degrees. Commonly used transistor type STA413A, STA464C up to 150 degrees on either the options to quit, or the case is broken.

cleaning nozzle health check

To clean the injectors they need to be removed first. You can certainly do in the engine but it is not desirable to contaminate the engine chemistry. Your task is to create pressure with chemicals for cleaning, and open / close the injectors periodically. The easiest way undertake audio terminal it is supplied to the battery Crown-9v, or the same 12v car battery and using the button or the circuit clicked. Through a connecting tube (homemade), connect the cylinder type Carbcleener under pressure and injector. Need to bind very strongly otherwise the nozzle will fly out. Pressed cylinder build up pressure pushed the button, repeat until normal spraying.
More intelligent and lazy way is to connect the injector or signal generator (not alternator!) or instead of PC speakers (active and passive, from the network) on which you run the program signals. Download signal generator PAS FREQUENCY GENERATOR. Adjust the frequency in the range 1-200Hz.
The hard way is the ultrasound, a great way to clean and remove the dirt to fine particles. Is to the atomizer is also have supplied a strong opening and closing. The disadvantage of this method that with the dirt to increase and the internal crack, or destroy the nozzle from the inside.
For checking the health of the nozzles is sufficient to supply voltage to the atomizer from the battery, the Krona, you should hear a click. A more correct way would be to check for \"file transfer\" by multimetro.

Volume nozzles which engines

A partially complete table of company Accel here. Another point, in addition as resistance atomizer is objem as I said above. Just tell you only a manufacturer KEIHIN. In General, there are only 2 volume 180 (190) and 235(240). In percentage ratio is 5 and 2 percent difference, respectively. The difference between 240 and 190 is 25 percent.
