PROJECT 1 - ENGINE WIRING HARNESS DESIGN

AIM - Route the wiring harness on given engine and prepare flatten view drawing in CATIA V5.

OBJECTIVE -

1. Route the wiring harness for V-16 engine.
2. Prepare flatten view drawing in CATIA V5.
3. Apply all packaging rules and industrial best practice.
4. Apply protection coverings as required.
5. Provide all necessary details like clearance, clipping/clamping selection, harness fixing requirements, harness continuity, assumptions if required.

Packaging rules and assumptions made in this project -

• Avoid harness routing and clipping in blind zone.
• Provide additional slack to the harness according to the surrounding 5-10% of slack is enogh.
• Provide enogh clearnace to the wiring harness with the respect to the surrounding.
• Provide guide channel if required.
• Use available holes for clamp and clip mounting.
• Enough clamps to be provided to ensure positive clearance with surrounding and safety of wiring harness.
• Distance between two clamps on straight branch should be maximum of 200mm.
• Use rubber grommet which provide proper sealing, protect harness from sharp edges, provide protection against vibration, and even act as a clamp.
• branch length should be minimum of 50mm.
• Minimum distance between clip and nearest branching point should be 25mm.
• Minimum distance between two breakouts should be 50mm.
• Limit the number of branches from single branching point to 4.
• Provide bracket for interconnection connector parking.

1. Download engine model on which wiring harness to be routed.
2. Creating context assembly.
3. Define electrical devices in electrical part design module.
4. Define interconnection connector (C-776438).
5. Define clips and clamps to be used for wiring harness.
6. Define furr clip for 20mm bundle diameter, this clip is define as support part.
7. Design and define plastic guide channel to guide the harness to the fuel injector ensor connectors.
8. Define plastic guide channel as electrical equipment.
9. Connect connector and coonector mounting electrically, in electrical assembly design.
10. Bundle segment, route defination.
11. Bundle protection.
12. Electrical harness flattening.
13. Final rendered view of wiring harness design for v16 engine.
