The major knots
The electronic block of management
The management block in an electronic box through многоштырьковый a socket receives the information:
On the basis of the information on number of turns and pressure in an inlet collector the management block counts duration of opening of the injectors put in action by an electromagnetic way, and, accordingly, quantity of injected fuel. For this purpose in the order of the block of management the characteristics of the engine representing meeting of the data about all conceivable situations of the engine, about quantity of fuel necessary for everyone situation and the corresponding moment of ignition are given. The management block can vary still characteristics after receipt of so-called correcting signals (for example, temperature of soaked up air and a cooling liquid).
The block of management throttle заслонкой
In the so-called block of management throttle заслонкой three separate knots known on other systems of injection as functional blocks are united.
It is in the distributor of fuel and regulates its pressure upon injectors. For this purpose the information on level of the lowered pressure in an inlet collector is transferred to it. Idling at closed throttle заслонке and very low pressure it holds lower pressure. With pressure drop at the raised loading on the engine the pressure regulator raises pressure of fuel. The fuel pump creates much higher operational pressure, but by means of a regulator of pressure return of gasoline to a fuel tank accordingly increases or decreases.
At each turn коленвала they inject gasoline into the channel всасывания in front of the inlet valve of the corresponding cylinder – duration is defined by the management block.
The gauge of temperature of soaked up air
At турбодвигателе capacity of 110 kw it is in воздухозаборном a hose and can precisely take temperature of air submitted турбокомпрессором. The information on temperature arrives in the block of management in the form of resistance size. It is used for an optimum dosage of fuel. Hot турбокомпрессор depending on a working condition strongly heats up soaked up air.
The gauge of temperature of a cooling liquid
The temperature of a cooling liquid is used at management of several functions of injection: at enrichment of a toplivno-air mix during start of the cold engine, послестартового enrichments (on all range of temperatures), at enrichment during accelerations and draught switching-off. The information on temperature of a cooling liquid is transferred in the management block also in the form of resistance size. He counts correct time of injection which in the heated-up engine makes from 2 to 8 мс. This size can increase almost on 70 % when the temperature goes down to the Arctic level–25 °С.
Measuring instrument of a stream of fresh air
In a stream of soaked up air there is an electrospending plate which is warmed up in the electroway. Depending on quantity of soaked up air its stream which cools a plate more strongly or more poorly varies. Temperature change causes change of electric resistance of a conductor. This measured size is used by the management block.
