BALINIT® DLC sets standards in the common rail system: the hard carbon coating ensures high resistance to attrition for tribologically stressed components of modern common rail injectors. These must withstand not only high compressive stresses but also simultaneous high abrasive attack by the very fine particle residues in the fuel. BALINIT® DLC enables these components to achieve the required lifespans.
