Increasing power of internal combustion engines with stroke volume enhancement, involves changing cylinder bore diameters or replacing cylinder sleeves for production crankcase, etc.

摘要

The method involves changing the diameters of the cylinder bores or replacing the cylinder sleeves for a production crankcase, fitting a new crankshaft with changed journals to increase the stroke and fitting a new connecting rod with changed length and diameter to achieve the best possible stroke-bore ratio, etc.
