Federal-Mogul Powertrain says it is now offering ultra high-strength iron cylinder liners made of a special form of compacted graphite iron (CGI), designated GOE330, that reduces the typical bore distortion under maximum piston side thrust by up to 27%, compared to existing iron materials. It is used in liner applications between 100 mm and 190 mm bore.
The off-highway sector – construction, agricultural and industrial applications – has been first to utilise the ultra high-strength liners, but the company says it also expects interest in the technology from marine, power generation and on-highway heavy-duty engine manufacturers.
