2.7. Control system, fuel system and system of decrease in toxicity
On cars the electronic control system of the engine, that is system of the distributed injection of fuel is applied. Distributed injection is called because for each cylinder fuel is injected by a separate nozzle. The system of injection of fuel allows to reduce toxicity of the fulfilled gases at improvement of rideable qualities of the car.
There are systems of the distributed injection with feedback and without it. In the present section only the short description of the general principles of the device, work and repair is given
systems of injection of fuel.
Engines of Hyundai have a control system with feedback. At it in system of release catalytic converter and the sensor of concentration of oxygen which provides feedback is established. The sensor traces concentration of oxygen in the fulfilled gases, and the controler on its signals supports such ratio air/fuel which provides the most effective work of converter.
In injection system without feedback converter and the oxygen sensor are not established, and for concentration adjustment WITH in the fulfilled gases serves WITH - a potentiometer. In this system the catching system паров gasoline is not applied also.
