Two-stroke engine with double pistons - has smaller piston for combustion chamber operation, air intake low compression larger piston for combustion chamber with high compression

摘要

Each cylinder has two pistons, of different sizes and located behind each other. The smaller piston operates the combustion chamber, the larger piston operates the compression chamber. The pistons are fastened to each other. The larger piston has the bearing for the gudgeon pin. Two cylinders with pistons offset by 180 degs. work together. The larger piston takes-in fresh air, compresses it, and passes it via a conduit into the combustion chamber of the twin cylinder. The high compression takes place in the combustion chamber. There is fuel injection, and combustion is acc. to the Otto- or Diesel principle. ADVANTAGE - Low construction; increased air intake; high compression; longer service life.
