The formula of piston for petrol engine comprises (wt%) Si 11%-13%, Cu 0.8%-1.5%, Mg 0.8%-1.3%, Mn 0.01%-0.2%, Fe 0.01%-0.5%, Ni 1%-1.5%, Zn 0.01%-0.2%, Ti 0.01%-0.2%, Te 0.1%-0.4%, Li 0.01%-0.1%, Co0.01%-0.1% and the rest is Al. Said piston can reduce gap between piston and cylinder jacket, and its working surface layer contains special substance capable of firmly combining with engine oil, so taht its sealing and antifriction properties are good, and it can prolong the life of engine.
