Two-stroke internal combustion engine

摘要

A two-stroke internal combustion engine is disclosed in which transfer of inlet air occurs from the aspiration chamber into the combustion chamber via channels running within the piston. The outer surfaces of the piston and the inner surfaces of the cylinder may with advantage be provided with heat resistant ceramic layers. Radial forces on the piston may be suppressed by means of a slidable piston guide cradle mounted on the cylinder block. Provision is made to inject water into an extension of the compression chamber. This greatly increases power output and also equalizes temperature and stresses in the cylinder walls. Heating means may be provided mounted in the cylinder end face of the combustion chamber.
