Pre-Calibration Checklist
1. Ensure the engine is at room temperature.
2. Check the engine oil level and top off as needed.
3. Verify the fuel filter is clean and replace if necessary.
4. Consult the Bosch diesel engine manual for specific instructions and guidelines.
Diesel Pump Setting
1. _Fuel Injection Timing_: 22-26° BTDC (Before Top Dead Center)
2. _Fuel Pressure_: 155-175 bar (2250-2535 psi)
3. _Nozzle Opening Pressure_: 155-175 bar (2250-2535 psi)
4. _Nozzle Spray Angle_: 120-140°
5. _Pump Delivery Volume_: 80-100 mm³/ stroke
Calibration Settings
1. _Idle Speed_: 650-850 rpm
2. _Maximum Speed_: 3300-3700 rpm
3. _Fuel Injection Quantity_: 45-65 mm³/ stroke
4. _Fuel Pressure Regulation_: 155-175 bar (2250-2535 psi)
5. _Timing Advance_: 12-15° BTDC (Before Top Dead Center)
Bosch Mechanical Pump Calibration Process
1. _Adjust the fuel injection timing_: Use the timing adjustment screw to set the fuel injection timing to the recommended specification.
2. _Adjust the fuel pressure_: Use the fuel pressure adjustment screw to set the fuel pressure to the recommended specification.
3. _Adjust the nozzle opening pressure_: Use the nozzle opening pressure adjustment screw to set the nozzle opening pressure to the recommended specification.
4. _Adjust the nozzle spray angle_: Use the nozzle spray angle adjustment screw to set the nozzle spray angle to the recommended specification.
5. _Check the pump delivery volume_: Use a pump delivery volume test kit to check the pump delivery volume and adjust as necessary.
Tools and Materials Needed
- Bosch mechanical pump calibration tool
- Fuel pressure gauge
- Nozzle opening pressure gauge
- Pump delivery volume test kit
- Timing adjustment screw
- Fuel pressure adjustment screw
- Nozzle opening pressure adjustment screw
- Nozzle spray angle adjustment screw
Additional Tips
1. Consult the Bosch diesel engine manual for specific calibration instructions and guidelines.
2. Ensure proper safety precautions when working with diesel engines and fuel systems.
3. Regularly maintain and inspect the pump and fuel system to prevent future issues.
4. Use genuine Bosch parts and calibration tools to ensure optimal engine performance.
Please note that these settings and procedures are general guidelines and may vary depending on the specific 6ET diesel engine and Bosch mechanical pump configuration. Always consult the engine manual and follow proper safety procedures.
