5. Control, decrease in toxicity

Arrangement of elements of the control system and decrease in toxicity of the fulfilled gases in a motor compartment of cars with the SOHC engine

And – the valve of ventilation of a case; In – the valve of system of catching of vapors of fuel.

Arrangement of elements of the control system and decrease in toxicity of the fulfilled gases in a motor compartment of cars with the DOHC engine

And – the valve of ventilation of a case; In – the valve of system of catching of vapors of fuel.

 

 

The scheme of the control system and decrease in toxicity of the fulfilled gases and catching of vapors of fuel

1 – oxygen sensor;
2 – catalytic converter;
3 – oxygen sensor;
4 – sensor of temperature of cooling liquid;
5 – spark plug;
6 – ignition coil;
7 – ignition lock;
8 – relay of management;
9 – ESM amplifier;
10 – valve of ventilation of a case;
11 – acceleration sensor;
12 – valve of a control system of idling rotation frequency; 		13 - ECM;
14 – measuring instrument of an expense and sensor of air temperature;
15 – air filter;
16 – sensor of provision of a butterfly valve;
17 – detonation sensor;
18 – the valve of cleaning of a canister with absorbent carbon;
19 – sensor of an angle of rotation of a bent shaft;
20 – fuel tank;
21 – a canister with absorbent carbon;

To reduce emissions of harmful substances in the atmosphere together with the fulfilled gases the following systems of decrease in toxicity of the fulfilled gases are used:

– system of catching of vapors of fuel;
– system of ventilation of a case;
– system of recirculation of the fulfilled gases;
– catalytic converter.
