62-518 DIAGNOSIS-ENGINE CONTROL SYSTEM

SYSTEM UNIT DESCRIPTION

No. Unit Quantity Function

Optimizing the control system according to the signal
1 Generator ECU 1 provided by the sensor makes it suitable for the engine
operating conditions.

It is used to measure the engine speed and determine
the engine phase, and the camshaft signal sensor
2 Phase sensor 1
together with the crankshaft position sensor provides
ECU with correct one-cylinder top dead center signal.
Crankshaft position Measure the engine speed and ECU calculates the
3 1
sensor engine speed based on the signal.

Coolant temperature Detect engine coolant temperature and determine the
4 1
sensor engine operating conditions.
5 Fuel injector 4 Inject fuel based on the signal from ECU .

Control the engine oil flow rate to the intake phase
6 Inltake VVT valve 1
adjuster and then control the intake angle of advance.
Control the engine oil flow rate to the exhaust phase
7 Exhaust VVT valve 1 adjuster, and control the exhaust gas retardation
angle.

Control the opening degree of the exhaust gas bypass
8 Exhaust control valve 1
valve and the boost pressure.
Canister solenoid Make the fuel vapor of canister enter the inlet channel
9 1
valve according to the ECU digital pulse square wave.

10 Knock sensor 1 Detect whether engine knocks .
11 Front oxygen sensor 1 Detect oxygen concentration in the exhaust gas.

12 Rear oxygen sensor 1 Detect oxygen concentration in the exhaust gas.
Detect the throttle position and controlling the opening
13 Electronic throttle 1 degree of throttle according to the electronic pedal
signal.

14 Idle speed regulator 1 Adjust the opening degree of the throttle valve.
Inlet pressure Detect the air temperature and flow into the cylinder
15 1
temperature sensor and control oil injection.

Engine oil pressure Measuring engine oil pressure and remind the driver to
16 1
sensor prevent damage to the engine.
Filter out impurities in the fuel to protect the oil injector
17 Fuel filter 1
and other components.

18 Fuel tank 1 Store fuel.
