To make fully sure about the effect of honing, the authors tested with a diesel engine which had both fine-bored and honed cylinders. Careful investigations were made on 1) cylinder : amount of wear (as measured by the air-micrometer), roughness 2) piston : amount of wear of piston and ring grooves, distribution of temperature 3) piston ring : amount of wear, tension, distribution of pressure, movement in cylinder, roughness and 4) compression pressure. After one year and a half measurement, the following conclusions have been reached : 1) Wear of a honed cylinder is smaller than that of a fine-bored cylinder at initial stage, but with regard to the total wear, there is no difference between them. 2) In other respects, there is no difference between them either. 3) So honed ordinary cast iron cylinders shorten the fitting time, but fine-bored cylinders serve the purpose in other respects.
