Presentation Transcript

  1. C13 OTE PC-10 Test Plan • Validate deposits and discrimination with ULSDF, CCV • Hardware and tolerances defined • Test conditions defined • Low Reference Oil (Ref #1) selected • High Reference Oil being sought • Two companies offering samples but no C13 test history • Possible to run new Oils in matrix • Fall back – test Best Commercial Oil run at PerkinElmer

  2. C13 OTE PC-10 Test Plan • CCV into intake worsens deposits • Introduces variability into deposit test • Risk of Engine performance changes due to blocked filters, turbos • Risk of Lack of oil discrimination • Increases Oil consumption • No time to establish discrimination with confidence on Piston and Turbo deposits. • Use Pseudo CCV system - present set-up but with simulated intake depression at CCV outlet (that is - CCV piped out of engine

  3. C13 OTE PC-10 Test Plan • First set of parts to tightened tolerances should be available 26 July • Pistons with dimensions and ring groove chamfers and groove finish available • Liners • Piston Rings • Top Rings - No Issues meeting tolerances • Second Ring – Issue with meeting tolerances (too thin) • Oil Ring – No Issue with meeting tolerances

  4. C13 PC-10 Plan Initial four test Mini-Matrix: All plans are still scheduled and on target (Sept 04) Fall back would be to run four stands concurrently Other work will be on-going to gain more confidence in Initial Oil Consumption Variability Caterpillar C13 Test Stand being worked on No new Oil and Additive Co. C13 Test stands run yet
