Pistons
• The shape of pistons has been changed due to the different requirements of direct
injecting petrol engines.
• The piston top is recessed to improve the mixture formation.
• The piston skirt was redesigned to fit to the new oil jet valves.
• The pistons are coated partially to reduce friction between piston and cylinder wall.
