Abstract

1435959 Two-stroke engines BRUNSWICK CORP 24 Oct 1973 [17 Nov 1972] 37476/75 Divided out of 1435958 Heading F1B The subject-matter of this Specification is identical with that described in Specification 1435958 but the claims are concerned with the provision of a shallow recess in an inlet passage immediately upstream of a cylinder port to define a sharp edge at the port to provide a flow through the port with a downward bias into the cylinder.
