5. Fuel Injection System
5-52
Data stream (2/3)
The screen showed the ECU captured by the engine of the state immediately.
The following data for the benchmark idling state:
● BARO------------ kPa (Above 98kPa) →Atmospheric pressure
● Intake Air---------- ºC (Outside Temp.) →Intake air temperature
● 2nd AIR VALVE------ V (Idle:ON) →Secondary air solenoid valve actuator state
● INJECT TIME---- mS(Idle:1~3mS) →Injection time
● IGN. ANGLE------------ (Idle:12~14) →Ignition timing
● STEP MOTOR ------ →Idle air control valve step motor actuator state
● CRANKSHAFT ---------- (Idle:CW) →Crankshaft functioning direction
● TEST TERMINAL-- (Idle:OPEN) →Test terminal state
● IDLE SET----------- RPM (=1650 RPM) →Idle speed goal set value
● ISC STEP--------------- (Idle:75~95) →Idle Air Control Valve stepper motor learning step
In the "DATA STREAM" of the screen use "▲" "▼" button to move the left side of the project "→"
symbol selected items, press the "ENTER" buttom lock of the project, and press the "F4" button
showed that the wave of projects.
Able to use "◄ left" and "right ►" button, can transform View wave numerical size.
Numerical analysis of images (2 / 3), the waveform can be displayed as shown in the following items:
y BARO
y Intaje Air
y INJECT TIME
y IGN. ANGLE
y IDLE SET
y ISC STEP
