Global warming has started to show its adverse effects on the environment. To improve the fuel efficiency and adhere to latest Euro norms automobile manufactures are shifting towards aluminum engines. These engines have as cast cylinder liners with special surface on the outer diameter commonly referred to as spiny lock or stiple finish. To improve rigidity and high thermal conductivity properties of engine blocks, Kusalava has developed different specifications of cylinder liners that have high adherence to aluminum blocks at the time of die casting by controlling the coarseness of the outer casting surface with the special coating materials and in-process controls.
