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; 22 – muffler. |
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.
