Detailed Engine Illustrations & Exploded Views

I need highly detailed, technically accurate illustrations of heavy-duty truck and equipment engines. The first assignment is a complete engine rendered as:

• A clean, full assembly drawing
• A precise exploded view that clearly separates every sub-component

Both drawings must be faithful to real-world dimensions and part relationships; experience with diesel engines or similar power-train systems will help you spot inconsistencies before they reach me. You may cross-check against OEM manuals, service schematics, or your own reference libraries—whatever ensures accuracy.

Deliverables
1. Full-assembly illustration – JPEG/PNG + PDF
2. Exploded-view illustration – JPEG/PNG + PDF
3. All working files retained so I can request edits or alternate formats later

Upon payment I receive exclusive copyright to the artwork. Please confirm your familiarity with engine components and describe how you will verify technical correctness when you reply.
