    摘要： A method of shaping the gudgeon pin bores formed in gudgeon pin bosses of pistons comprises introducing into the bores portions of a shaped pin. A load is applied to the pin and the direction of the load and the shape of the pin are chosen so that areas of bore-defining walls of the bosses subjectto high stresses in use, and therefore liable to crack, are radially outwardly deformed to reduce the incidence of cracks.

    摘要： In a piston and cylinder assembly in which the piston is made of an aluminium alloy, the wall of the cylinder contacted by the piston is formed of a hyper-eutectic silicon aluminium alloy having the composition by weight percentages of silicon (Si) 12 - 20%; copper (Cu) 0.5 - 5%; iron (Fe) 1.0 - 6%: magnesium (Mg) 0.2 - 2%; nickel (Ni) 0.5 - 4%; and optionally manganese (Mn) 0 - 5%; cobalt (Co) 0 - 3%; chromium (Cr) 0 - 3%; tin (Sn) 0 - 8%; titanium (Ti) 0 - 0.3%; lead (Pb) 0 - 5%: and molybdenum (Mo) 0 - 5%, the remainder being aluminium.
