Abstract

PURPOSE: To display sufficient chatter-mark resistance, scratch resistance and wear proof even when using gasoline containing lead, by plating an inner circumferencial surface with chrome in the compound porous types of a pinpoint type and a channel type.
CONSTITUTION: This engine is produced by combining a rotor housing, which is manufactured to ensure that pinpoint type pores with 5W40% porosity and channel type pores with 5W40% porosity exist within a 10W60% total porosity range and a ratio of said both types is within a range between 1:3 and 3:1, with an inner circumferential surface plated with chrome with Hv 930W1200 hardness and by combining an apex seal consisting of the material of a cast iron base, which carbide is 50W75 volume % and which hardness is Hv 700W900, with a sliding surface.
