Monitoring systems and decrease in toxicity of the fulfilled gases

General information

Work of system of injection of fuel is based on sequence of impulses and measurement of a consumption of air. The system provides giving in cylinders of the engine of a toplivnovozdushny mix of optimum structure. The system of absorption of air and system of injection of fuel work together with system of electronic control by the engine. All sensors and switches incorporate to ESM which processes arriving data and calculates installation of phases of a gazoraspredeleniye and duration of opening electricly operated fuel nozzles.

The main requirement for optimum supply of fuel is defined by the data arriving on ESM from the sensor of a mass consumption of air. Other sensors and switches are used for the following measurements:

– temperatures of cooling liquid;
– frequencies of rotation of a cranked shaft of the engine;
– contents of oxygen in the fulfilled gases;
– definitions of provision of the top dead point of the piston of the first cylinder in a compression step.

Arrangement of elements of the monitoring system and decrease in toxicity of the fulfilled gases in a motor compartment of cars with engines of 1,6 l and 1,8. 2,0 l

1 — the sensor of absolute pressure in an inlet collector (MAR)
2 — the sensor of temperature of soaked-up air (IAT)
3 — the sensor of temperature of cooling liquid (eats)
4 — the sensor of provision of a butterfly valve (TPS)
5 — the sensor of provision of a camshaft (CMP)
6 — the sensor of an angle of rotation of a cranked shaft (CKP)

7 — the bogrevayemy sensor of oxygen
8 — nozzles
9 — the modulator of frequency of idling (ISA)
11 — the detonation sensor
12 — the blocking switch
15 — the relay of the compressor of the conditioner
16 — the electromagnetic valve of system of catching паров fuels (PCSV)
17 — the operating relay
18 — the ignition coil

Various sensors and switches inform on any changes of operating conditions and send the corresponding signals to ESM. It allows ESM to regulate duration of opening of nozzles and to support an optimum mode for decrease in toxicity of harmful substances in the fulfilled gases and power setting in various service conditions of the car.

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:

– catching system паров fuels;
– system of ventilation of a case;
– system of a retsirkulyatsiya of the fulfilled gases;
– catalytic converter.
