Rheinmetall Automotive AG, a first-tier auto-industry supplier has got another contract through its group subsidiary KS Kolbenschmidt to manufacture steel pistons for car diesel engines. The order is worth a total of €45 million (Rs 328 crore).
For a 6-year period starting from 2019, these steel pistons will be manufactured at Kolbenschmidt's Czech location at Ústí nad Labem. The customer is a premium-segment OEM (Original Equipment Manufacturer), will be fitting the steel pistons in a new generation of diesel engines and so far they haven't used any steel pistons.
Currently, in the premium segment market, the trend is to use steel pistons for engine developments. Comparatively, steel pistons are shorter than their aluminium counterparts and with it's longer connecting rod, will help to reduce friction inside the engine.
Thus decreasing the fuel consumption by 4 percent and correspondingly lower CO2 emissions. KS Kolbenschmidt has been supplying steel pistons for another premium manufacturer since 2014.
The fact is, steel is much stronger than aluminium, which allows an approximately 30 percent reduction in overall height. Recently, Rheinmetall got a massive order from an international customer for military trucks for a whopping amount of Rs 972 Cr.
