Abstract
Four different liner finishes were tested in a 7.6 L, 179 kW four stroke diesel engine. The primary motivator of the tests was to examine the effects of plateau honing on both rough (Ra ≈ .77 μm) and smooth (Ra≈.26 μm) liners. Measured effects were oil consumption, blowby, ring wear, and liner wear. The engine tests (some to 1100 hours) show that a smooth, plateaued liner offers the best finish for this engine with regards to oil consumption, ring wear, liner wear between the ring turnarounds, and volume of liner material lost due to wear.
