Systems of immersion of toxicity of the edition - the general information
General information
Petrol models In systems of power supply of all petrol models only neetilirowannyj gasoline has to be used. The tax system the motor functions so that to receive the maximum compensation of the motor at the minimum costs of fuel and toxicity of the working gases. The ulawliwanija parow system of fuel prevents its meeting from the tank in the atmosphere. The rezirkuljazii system of the working gases is defined. Charts of the sequence of systems of immersion of toxicity of the working gases (as parts of tax system the motor) The chart of the sequence of system of an injection wdigatelej 119 and 104 (the motor 119 is shown)

System of ventilation kartera (PCV) For elimination of a vytecheniye of not burning down hydrocarbon in the atmosphere the motor is condensed completely. Gases and vapors of oil which is formed in kartere by means of the surge protector get to the pipeline of access and burn down in the cylinder together with fuel.
Gases move away from kartera for the account from distinction of pressure in kartere and the pipeline of access (pressure in kartere is higher). Immersion of toxicity of the working gases For immersion of number of harmful marriage in the atmosphere on all petrol models in system of the edition the 3-functional catalytic reformer is established. The tax system an injection of fuel has the return coupling in which the oxygen sensor is made. This sensor which is defined in system of the edition constantly informs the control unit on composition of the working gases. Depending on the obtained data, the control unit corrects quality of mix which in cameras of burning and is served, combustion of fuel optimizes thus.
The heating element which is accepted by the control unit of the special relay is installed in the probe ljambda. The working surface of the probe ljambda is sensitive against change of content of oxygen in gases. Depending on concentration of oxygen, the sensor sends signals of various effort. If the mix pereobogaschtschena - the content of oxygen signals in the working gases very low, a sensor with low effort. The effort increases depending on impoverishment of mix and increase in content of oxygen in gases. Most effectively the reformer at optimum composition of gas mixture works (14.7 parts of air in 1 part of fuel). At optimum concentration of oxygen in the working gases the jump happens in effort on a sensor. This jump is point of calculation for the control unit at correction of quality of mix.
It is defined to 2 sensors. - before, and the second - after installation of the catalytic reformer. From this reach more exact observation of composition of the working gases. The rezirkuljazii system of the working gases (EGR) The rezirkuljazii system of the working gases allows to reduce the number of NOx in the working gases. A small part of the working gases is served for this purpose in the access pipeline as the special gate. The gate of the rezirkuljazii system copes from the control unit. Ulawliwanija parow system of combustible (EVAP) Address schemes of tax system the motor (tax system the motor of models of 3.2 l, tax system the motor of models 4.2 and 5.0).
For immersion of marriage in the atmosphere of not burning down hydrocarbon on all petrol models the ulawliwanija parow system of fuel is installed. The tank tank neck densely becomes covered, under the tank the coal adsorber is defined. There fuel vapors which is formed in the tank during a stop of the car gather and there remain, to a control unit signal blowing off of the filter will begin. Then vapors of fuel begin to be served as the gate () Durchblasens in the access pipeline, there they burn down mix up with working mix further in the usual way in burning cameras.
The control unit considers the gate of the motor closed by supply of normal work on not aggravated changes and to Anheizzeit. Thus the meeting of not burning down fuel is prevented in the reformer (at the increased idling changes the mix pereobogaschtschena). After warming up of the motor the gate begins to reveal and be closed, to the highway of access giving fuel vapors. Diesel models The tax system the motor functions so that to receive the maximum compensation of the motor at minimum costs of fuel and toxicity of the working gases. For additional immersion of toxicity of gases on the car a little additional systems are defined. The system of ventilation kartera reduces a vytecheniye of gases in the atmosphere from the Schmierens system of the motor. The catalytic reformer reduces toxicity of the working gases. The rezirkuljazii system of the working gases is defined. System of continuous ventilation kartera (PCV) For elimination of a vytecheniye of not burning down hydrocarbon in the atmosphere the motor is condensed completely. Gases and vapors of oil which is formed in kartere by means of the surge protector get to the pipeline of access and burn down in the cylinder together with fuel.
Gases move away from kartera for the account from distinction of pressure in kartere and the pipeline of access (pressure in kartere is higher). On all diesel models the gate of ventilation is defined. It is on a cover of the head of the block and operates current of gases from kartera. Catalytic reformer For immersion of number of harmful marriage in the atmosphere on all diesel models in system of the edition the catalytic reformer is established. It neutralizes the most part of gaseous hydrocarbon, With and other harmful adulterations which form the working gases. The rezirkuljazii system of the working gases On all diesel models the rezirkuljazii system of the working gases is also defined. This system allows to reduce the number of NOx in the working gases. A small part of the working gases is served for this purpose in the access pipeline as the special gate. The gate of the rezirkuljazii system is controlled by the control unit. |
