AD07.54-D-3000-02A | Function check of the actual values for the engine - diagnosis of the gas injection and ignition system (pressurized engine control) |
Function check of actual values using the HHT (check engine)
Actual value no. | Actual value | Specification |
| Coolant temperature | > 80°C |
| Engine speed | 750 50 rpm |
| Injection time | 2.1 - 2.6 ms |
| Lambda control (in case of a complaint, the lambda control at idling speed and at 2,500 rpm must be measured) | 0 10% |
| Throttle valve angle | 0.3 - 2.5° |
| Intake manifold pressure | 600 50 mbar |
| O2-sensor voltage (fluctuates either side of 300 mV after 2 minutes) | - 200 to +1000 mV |
| Self adjustment of idling (basic position for idling: 0.0 ms. If idling < 0.0 ms (negative value), the fuel mixture is tending to "rich". If idling > 0.0 ms (positive value), the fuel mixture is tending to "lean") | 0 0.2 ms |
| Self adjustment factor partial load (basic position for partial load: 1.0. tendency "rich" < 1.0. Tendency "lean" > 1.0) | 0.85 - 1.15 |
| Ignition angle (the ignition angle is used for idling speed stabilization which means that the ignition angle can deviate in extreme cases for short time by 10° from the specified value) | 5 5° crankshaft angle BTDC |
| Deceleration fuel shutoff (idling) Engine speed > 2100 rpm | Readout: OFF Readout: ON |
| Ignition coil operating period | 0.65 - 2.6 ms |
| Ignition coil operating voltage | > 28 V |
| Ignition coil fault counter | < 255 |
| Exhaust flap | Display: CLOSED |
| Gas pressure (relative pressure) | approx. 7.2 bar |
| Gas temperature | °C |
