For Heavy Duty Diesel Engines for Power Generation/Off Highway Vehicle applications, MPL develop and produce Pistons with diameters ranging from 130 mm to 190 mm featuring Single Alfin and Dual Alfin Gravity Die Cast Pistons.

MPL manufacture these Pistons on a special manufacturing facility with special purpose CNC Machines to produce complex OD  Profiles, and Pin bores with Oval Bore, trumpet bore  or relief's as per the requirement.

The complicated Core Profiles featuring on these Pistons are generated applying 3D Modeling facilities using Pro-E Wildfire-2 foundation package for surface modeling, advanced modeling extension and Tool Design  Package for manufacturing to achieve targeted sections and effective control on the weight of the Piston for optimum balance of  reciprocating masses.

Some of the special features which are provided in the design of these bigger size Pistons  (Diameters of 110 mm to 170 mm range)

·    Hard Anodizing of the Crown for Thermal Crack Protection
·    Dual Ring Carrier for enhanced life
·    Oval Gudgeon Pin Bore
·    Pistons with as cast side drain for effective Oil drain

Two pieces constructions of Pistons (ARTICULATED PISTONS) with forged Chrome Moly Steel Crown coupled with Aluminium Alloy Skirt held together by a Piston Pin  where the guidance and sealing function are separated from one another.  Because of this design, the skirt is better shielded from hot Piston crown and ring Zone and can, therefore, be installed with smaller clearances than the one-piece Piston, which has a positive effect on Quiet run
