The gauge of temperature of a cooling liquid will screw in the pipeline on which the cooling liquid from both heads of cylinders circulates. Thus it is a question of the thermometer of resistance (NTC-resistance) in which resistance changes according to engine temperature. The information on temperature of a cooling liquid serves as the correcting factor for an advancing of ignition and duration of injection at the cold and hot engine. Other functions, such as management of a detonation and рециркуляция the fulfilled gases, join at the corresponding temperature of the engine.
The gauge of an advancing of ignition is inductive, it is established on the left side картера the engine. The signal of the gauge of an advancing of ignition is necessary at engine start-up, that together with signal of the gauge of the Hall to define ВМТ in the third cylinder of the engine at the moment of ignition. In the absence of a signal the engine is not started.
The Hall gauge is at a back end face of the left head of cylinders. The principle of work of the gauge is stated at the description of distributive system of ignition. The gauge signal is necessary at engine start-up, that together with signal of the gauge of an advancing of ignition to define ВМТ in the third cylinder of the engine at the moment of ignition. In the absence of a signal the engine is not started.
The gauge of frequency of rotation of a cranked shaft will tighten at a gear wreath of a flywheel. Its signal allows the management block to calculate an advancing of ignition and the moment of the beginning of injection. In the absence of a signal the engine is not started.
The switch of idling and potentiometer throttle заслонки are located in the general case at knot throttle заслонки. They define for the block of management position throttle заслонки. Thanks to it, in particular, copes движковый the switch as until contact of the switch of idling is not included and simultaneously frequency of rotation of a cranked shaft exceeds certain value, the management block blocks fuel giving to the engine.
Both gauges of detonation combustion are located from the interior of blocks of cylinders in the top part of average cylinders a little below heads of cylinders. Selective regulation of a detonation provides maintenance of an advancing of ignition on border of a detonation and automatically adapts to quality of used fuel. Detonation regulation allows to have to the engine high degree of compression. Thanks to it energy of fuel is better used that simultaneously conducts to decrease in its expense. The regulation system includes gauges of detonation combustion and corresponding analyzing electronics. Owing to high degree of compression of the engine there can come detonation combustion which at certain duration causes engine damage. That it to avoid, gauges of detonation combustion which register infringements of combustion are required and care of changing an ignition advancing on more later. At failure of the gauge of detonation combustion the management block automatically rearranges an advancing on more later so that the engine has not received damages. First of all, it is connected with reduction of capacity which also comes when instead of unleaded gasoline Super (PETROL 95 or PETROL 98) in a fuel tank it it is filled in ordinary Unleaded gasoline (PETROL 91).
Both oxygen gauges are screwed in corresponding final branch pipes. They measure in cars with the adjustable catalyst the oxygen maintenance in the fulfilled gases and send a corresponding signal of pressure to the management block. According to it the management block changes qualitative structure of a soaked up toplivno-air mix so that in the catalyst the fulfilled gases optimum burn down.
