Abstract
For introduction of the pistons with piston rings, bevels have to be arranged on the cylinder bore. These bevels are usually arranged on the cylinder top surface and are used to position a compressor. As a result, dead spaces which occupy a relatively large volume are formed in the region of the combustion chamber, in which dead spaces only inadequate combustion takes place, which may have an adverse effect on the raw emissions. According to the invention, there is provision for a run-up cone, which is used for introduction the piston and compression of the piston rings, to be fitted at the crankshaft-side end of the cylinder bore.
