Abstract

193,948. Vandervell, C. A. Nov. 29, 1921. Cylinders, varying clearance of and liners for.-An adjustable liner c is moved simultaneously with the engine throttle to vary the compression space according to the quantity of mixture admitted. The liner may have a helical movement in the cylinder and may enter a circular recess in the head. The liner may have projections entering correspond. ingly shaped recesses in the head.
