Powertrain Parts Cylinder Liners With the recent demands for fuel efficiency, higher performance, and lighter weight engines, there is a growing trend for improving cooling performance, reducing clearance between cylinders, and using aluminum engine blocks. Consequently, TPR is striving to improve adherence to the aluminum block by applying centrifugal casting method to make liners thinner, and thereby achieve lower costs. Cylinder Liners

Cast-in cylinder liner

Cast-in cylinder liner

【Features】
We can achieve low-cost through making As-cast spiny type. (Centrifugal casting method)It is superior in adhesion with aluminum by special As-cast spiny type.
【Applications】
Various cars with aluminum engines

Thin wall dry liner

Thin wall dry liner

【Features】
The relatively small cylinder bore distance makes it possible to design the engine smaller and lighter.
【Applications】
Diesel engines for automobiles and motor sports

Nitriding cylinder liner

Nitriding cylinder liner

【Features】
This cylinder liner has a stiffened nitride layer on the inner surface, where sliding friction occurs, with improved wear-resistance and anti-galling properties.
【Applications】
Diesel engines for automobiles and others

Phosphate coating cylinder liner

Phosphate coating cylinder liner

【Features】
There are specifications for both dry and wet types which have excellent anti-galling properties.
【Applications】
Diesel engines for automobiles

Wet liner

Wet liner

【Features】
Outer chrome plating is applied to prevent cavitation.
【Applications】
Diesel engines for automobiles
