7.10. Units of control and measuring system with the processor ECCS block - general information10. Units of control and measuring system with the processor ECCS block - general information
System of direct injection of fuel
1. The processor block processes information from sensors and operates work of systems of ignition and fuel injection, supporting a stekhiometrichesky ratio of gasoline and air. The block also provides diagnostics of systems and includes control lamps. The stabilized source is built in the block for a food of various sensors.
2. The sensor of rotation of the crankshaft (photo) develops the main signal for the ECCS block. Consists of a rotor with slot-hole structure and the shaper assembled on optical pair. On a rotor there are 2 groups of cracks - located through 1 ° (for rotation registration) and the pair cracks located through 120 ° (for registration of turn of the crankshaft relatively VMT).
Sensor of speed of a stream
3. The sensor of termoanemometrichesky type, is intended for measurement of a volume consumption of the air submitted to cylinders (photo).
