5.4. Gauges and executive mechanisms of a control system of the engine

THE GENERAL DATA

Arrangement of elements of a control system of engine MOTRONIC in a motor compartment with the engine 1,8-I

1 – the gauge of temperature of a cooling liquid;
2 – the valve of adjustment of position of a camshaft;
3 – the throttle case;
4 – an electric socket of black colour of the gauge of oxygen;
5 – an electric socket of grey colour of the gauge of turns of a cranked shaft;
6 – an electric socket of green colour of the gauge of a detonation 1;
7 – an electric socket of dark blue colour of the gauge of a detonation 2;
8 – the block of engine management MOTRONIC;
9 – the gauge of number of turns of a cranked shaft; 10 – the gauge of a detonation 2;
11 – the valve of switching of channels of system of giving of air;
12 – the gauge of temperature of air arriving in the engine;
13 – the gauge of a detonation 1;
14 – the Hall gauge;
15 – fuel atomizers;
16 – a regulator of pressure of fuel;
17 – the ignition coil;
18 – the warmed gauge of oxygen;
19 – connection with weight of the car. Connection is located on a support of the power unit;
20 – a measuring instrument of weight of air;
21 – the magnetic valve of the coal filter. The valve is located on the air filter.

The air filter and measuring instrument of a stream of air on the engine 1,8-I/150 h.p.

1 – air branch pipes;
2 – a filtering element of the air filter;
3 – a sealing ring;
4 – a measuring instrument of a stream of air;
> 5 – an air route;
6 – a bolt, 6 Nanometers;
7 – a cover of the air filter;
8 – a bolt, 6 Nanometers;
9 – the gauge of step productivity; 10 – a lining;
11 – a sealing ring;
12 – the pipeline;
13 – a bolt, 10 Nanometers;
14 – a thermofilter;
15 – the rubber plug;
16 – распорная the plug;
17 – a support;
18 – the case of the air filter

The switch throttle заслонки informs the block management on position throttle заслонки idling. The management block slightly opens or covers through a servomotor throttle заслонку and thus supports stable turns of idling.
Gauges of temperature of a cooling liquid and temperature of air arriving in the engine at the expense of change of the resistance at temperature change inform the engine management block corresponding temperatures.

The system of catching of steams of fuel consists of the filter with the activated coal and the magnetic valve. The filter of the activated coal interferes with that harmful steams of fuel got from a fuel tank into atmosphere, and evaporating fuel collects in capacity with the activated coal. At work of the engine of pair fuel under the control of the magnetic valve again move in the engine for reburning.

The oxygen gauge measures the oxygen maintenance in a stream of the fulfilled gases. The management block on its signal supports the maintenance of harmful emissions in the fulfilled gases at the lowest level. At cars with the catalyst the structure of the fulfilled gases is supported at the level providing the best reburning in the catalyst.

The detonation gauge serves for detection of the beginning of a detonation in cylinders of the engine and on the basis of this information the engine management block reduces a corner of an advancing of ignition. In the presence of malfunctions of ignition the management block blocks fuel giving in the corresponding cylinder.

The engine 1,8-I ADR, engine V6

On these engines the system of giving of air in the engine of variable length which depending on operational modes of the engine changes length of a way of air arriving in cylinders is applied. It is for this purpose used rotary заслонка, put in action пневматически. On low turns of the engine air arrives on longer way and, using a resonance, there is fuller filling of the engine therefore the twisting moment raises.

Engine V6

On these engines depending on engine turns occurs доворачивание the distributor ного a shaft operating inlet valves therefore phases timing change. Installation of optimum phases timing for corresponding turns of the engine raises capacity of the engine on all turns.
