Units of control and measuring system to the processing unit ECCS -General information
10. Units of control and measuring system to the processing unit ECCS -General information The system of direct fuel injection 1. The processor unit processes data from the sensors and controls operation of the ignition system and fuel injection while maintaining the stoichiometric ratio of fuel and air. The unit also provides diagnostics systems and includes indicator lights. The block is integrated stabilized power supply for the various sensors. 2. The sensor of crankshaft rotation (picture) generates the main signal for the ECCS. It consists of a rotor with slotted structure and generator assembled on the optical pair. On the rotor there are two groups of slots - located at 1 ?� (rotation for registration) and paired slits, spaced 120 ?� (for registration with respect to crank TDC). Flow velocity sensor 3. Hot-film sensor type, designed to measure the volumetric flow rate of air supplied to the cylinders (see photo).

Motor temperature sensor 4. The sensor detects the temperature of the coolant and is connected to the processing unit (picture). Exhaust sensor 5. Screwed into the exhaust manifold, for monitoring the oxygen content of the exhaust gas (see photo). Switch Throttle 6. It is intended to identify idling. At idle, the sensor pins are closed by pressing a pedal throttle contacts open (photo). Vehicle speed sensor (VSS- probe) 7. Designed to signal the vehicle speed supplied to the processing unit, is integrated in the speedometer. In the pointer speedometer sensor is a reed switch, a digital sensor is designed as a pair with the optical pulse shaper. Knock sensor 8. Knock sensor of the piezoelectric type, designed to determine the detonation in the cylinders (photo).

Ignition coil 11. It is intended for high-voltage pulses (photo). The bypass valve (AAS- valve) 12. Adjust the amount of air supplied directly into the cylinders at idle, bypassing the throttle. Managed by the processor unit. Stabilizer idle speed (block IAA) 13. It consists of a bypass valve and the adjusting screw. It designed to stabilize the idling (see photo). Pneumatic valve recycling 14. Controls the amount of exhaust gas flowing into the intake manifold through a valve cone, rigidly connected to the vacuum diaphragm (photo). Recirculation solenoid valve Bridging the vacuum channel 15. Aperture Pnev-moklapana recycling in response to interrupt signals to the processor unit (photo). When the solenoid disconnected from the manifold vacuum is supplied to the pneumatic valve. When the solenoid valve plug closes the vacuum port.

Fuel pump 16. Immersion is mounted in the tank (see photo). Airflow control 17. Provides switchover cold engine idle speed is increased due to the opening of the passageway (photo). It consists of a thermo valve. Air ejection valve (AIV-valve) 18. Provides a flow of air into the exhaust manifold due to the ejection of the need for post-combustion residues of incompletely combusted fuel (photo). When the pressure in the reservoir triggered a return reed valve, preventing gas from entering the air filter.

The pressure sensor in the hydraulic booster 20. The sensor is screwed into the high-pressure power steering pipe. The signal from the sensor is used to adjust the idle speed when the power steering (photo). Air temperature sensor 21. It is intended to adjust the ignition timing at an elevated temperature of the air in the reservoir to prevent detonation (photo). Injection system with preliminary preparation of combustible mixture 22. The system includes one or two nozzles mounted on the throttle body. Processing unit injectors. Many units of this system are similar to those of direct-injection units (photo).
