Engine Performance Additive Specification Example for Fleet Maintenance: Adjustable Type

This is a worked specification for engine performance additive in a adjustable type programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The adjustable type version exists because the duty cycle on fleet maintenance is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Semi-Metallic Compound, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • cold forging
  • powder coating
  • laser cutting
  • ultrasonic cleaning
  • die casting
  • sintering

Where this example applies

Programmes that run adjustable type most often specify this build for fleet maintenance. Related applications include agricultural trailers, scooter fleets, city buses, delivery vans, boat trailers.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 1.5 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.

What is the minimum order quantity?

The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO 9001-compliant build instead of a fresh interpretation.

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
