6.3. System of injection of MPI/MPFI (6-cylinder engines)

6.3.1. Introduction

GENERAL INFORMATION

Systems of injection of MPI (Multi-Point-Injection) and MPFI (Multi-Point-Fuel-Injection) are called as systems of multipoint injection. They have the combined system of ignition and injection with the uniform control unit. In this subsection it is a question of a part of the system connected with injection.

Details of system of injection of MPI
1. Fuel filter
2. The electromagnetic valve of system with absorbent carbon
3. Measuring instrument of a mass consumption of air
4. Index of level of oil
5. Air filter
6. Hose of system of preliminary heating
7. Clock valve
а) for system of a retsirkulyatsiya of the fulfilled gases
б) for system of switching of an inlet collector
8. Returnable топливопровод
9. Air hose
10. LFR valve of system of regulation of filling
LFR = Leerlauffullungsregelung
11. Regulator of pressure of fuel
12. Ring топливопровод
13. Hydraulic pipeline of the pump of the amplifier of the steering mechanism
14. 3 dual coils of ignition
15. Remenny pulley of the pump of the amplifier of the steering mechanism
16. Casing of a poliklinovy belt
17. A wire of a high voltage to a cylinder 4 spark plug
18. Klapanny nozzle
19. A switched inlet collector
20. Membrane mechanism of switching of an inlet collector
21. Cover of a quencher of noise
22. Noise quencher
23. Delivery топливопровод
24. Hose of system of ventilation of a case
25. Cover of electric wires
26. Cover of a head of cylinders
27. Left cover of a gear belt
