Abstract

In an i.c. engine, the connecting rod connecting a piston to the crankshaft is made of a forged Al alloy contg. 10-20% Si and is connected directly (i.e. not via a bearing) by >=1 of its two holes to a crankpin of the crankshaft and/or to a pin in the piston. The connecting rod is light and hard and has sufficiently good sliding and wear properties that costly bearing collars can be omitted.
