Piston-piston pin-arrangement for passenger car diesel engine, comprises piston made of steel material, where compression height of piston amounts to certain percentage of piston diameter

摘要

The piston-piston pin-arrangement (10) comprises a piston (11) with a piston base (15) and piston hubs (19), where the piston hubs are connected with the lower side of the piston base through hub connections (21) and are provided with hub bores (23) for accommodating the piston pins (12). The piston is made of steel material. The compression height (KH) of the piston amounts to 37 to 45 percent of the piston diameter (KD). The piston pin diameter (BD) amounts to 33 to 38 percent of the piston diameter, and the piston pin length (BL) amounts to 57 to 63 percent of the piston diameter.
