PISTON TYPES
Piston skirt and crown
Consist of a steel piston head and an aluminium piston skirt which
have a moveable connection to each other via the piston pin. Due to
great strength and low wear and tear, it is possible to achieve low
exhaust emission values for diesel engines that are subjected to
particularly high loads.
Piston comes with bushes
In order to make it possible to increase the loads to which the pin
boss can be subjected, this piston has pin boss bushes that are
made of a special material
Alfin Pistons
Alfin is inserted within the ring grooves when casting. Alfin is
made of special austenitic cast iron. It is tightly bonded
metallically to piston body and counteracts the wear in the top or
second ring groove.
Cooling channel piston
Cooling channel piston effectively reduce piston body working and
groove land temperature under high temperature working condition.
PISTON SURFACE TREATMENT
Piston with Tin coating
Tin is coated by exectroanalysis or heat dipping at thickness
between 0.001 and 0.003mm. Tin is characterized as soft and
oil-friendly which improves running-in efficiency of piston and
liner.
Pistons with Phosphating
The phosphating is aimed to improve initial running-in performance.
The phosphating layer is easy to wear off and helpful to improve
running-in.
Piston roof anodizing
The piston roof is anodized by electrobath, forming thin layer of
Al O . This treatment will improve heat resistance, heat
conductivity and anticorrosion, it helps prevent piston roof
burn-up.
Graphipe printing and spratyed at piston skirt
Graphite is characterized as good lubriing, which helps lubricant
adhering to coating surface.
