Who can tell me how many systems the traditional electronically controlled automobile engine is divided into? What are the main systems?

My heart beats when I look at the reward points. . .

There are too many details. . . . I happened to be in this business.

Let me start by saying:

1. Air intake system: air filter, air intake hose, throttle valve, air intake manifold, carbon canister and carbon canister solenoid valve.

2. Fuel injection system: fuel nozzle, oil pressure regulating valve, fuel nozzle pipeline (part of oil pressure rail), oil inlet pipe, oil return pipe, oil pump assembly (oil pump and oil pressure regulator), fuel filter and oil tank.

3. Ignition system: ignition controller, cylinder pipeline, spark plug (some are distributors).

4. Exhaust system: exhaust pipe, muffler, oxygen sensor (including front and rear oxygen), ozone catalysis, etc.

5. Cooling system: coolant tank, liquid level sensor, water tank, radiator, cooling fan, temperature control switch, thermostat, landscape pipe, sewer pipe and vehicle water pipe.

6. Control unit system: computer board, fan controller, including various sensors and relays.

7. Starting system: starter and starting relay.

8. Charging system: generator

9. Display system: instrument cluster

10, anti-theft system: diagnosis seat, anti-theft device, reading coil, key chip (the higher the car grade, the different it is, which is very complicated)

1 1. Power supply system: battery, relay box, fuse box and battery clip.

I won't say mechanical. . . .

Give the best answer. . . . I finished the task.
