MAHLE, EVOTEC® 2 gasoline pistons


MAHLE’s EVOTEC® 2 is a lightweight aluminum piston with a very high structural strength especially designed for modern gasoline engines. 

The new MAHLE piston also enables the development of modular systems that can include ring carriers (RC) and salt-core cooling channels (SC) based on specific customer requirements.

MAHLE’s basic EVOTEC® design features a narrow skirt on the thrust side of the piston and an elastic broad skirt on the anti-thrust side. MAHLE engineers further optimized the design to increase structural strength and reduce weight by approximately five percent.

An EVOTEC® RC piston with a ring carrier and an EVOTEC® SC with a cooling gallery significantly expand the ability of the EVOTEC® 2 for raising power densities and increasing robustness, as well as providing further reductions in CO2
emissions. A piston combining RC and SC technology currently is under development.
