Attention: When carrying out maintenance work or replacing components of the fuel supply system, observe the appropriate safety precautions.
1. Electronic system (see resist. illustration) diesel engine management provides the following features:
- a) Accurate fuel dosage in any operating mode, which ensures low fuel consumption at high power;
- b) Reducing the content of harmful substances in exhaust gases due to accurate fuel dosing and the use of a catalytic converter;
- c) Idle speed and maximum engine speed limitation are set and adjusted automatically
- d) Self-diagnosis of the engine management system provides the ability to quickly troubleshoot.
15.1 Sensors and modules of the diesel engine management system (on the example of engines Y20DTH/Y22DTR): 1. Atmospheric pressure sensor; 2. Solenoid valve for charge air pressure control; 3. Fuel pedal position sensor; 4. Vacuum receiver; 5. Vacuum control valve; 6. Preheat system control module; 7. Automatic vacuum tank valves - boxes; 8. Solenoid damper switch; 9. Electromagnetic throttle valve.; 10. Boost pressure sensor; 11. Vacuum chamber throttle; 12. Pulse sensor crankshaft; 13. Engine oil temperature sensor; 14. Distribution injection pump of plunger type; 15. Coolant temperature sensor; 16. Air mass measurement sensor
2. Elements of the engine control system maintain high performance for a long time and require virtually no maintenance. Only such elements of the power system as the air and fuel filters need regular replacements during the maintenance of the car.
