MAHLE has developed a low compression height steel piston for heavy-duty
applications. The MonoLite® steel piston enables a significant reduction in
engine block deck height. The combination of engine block and piston mass
reduction contribute to improve fuel economy. Extensive testing has proven an
intrinsic thermal efficiency benefit for steel pistons. Due to thermal expansion
ratio of steel, a tighter installation can be realized while maintaining superior
scuff resistance, as well as a consistent running clearance to the liner over the
entire temperature range.
MAHLE’s MonoLite® design offers several advantages:
■ Lightweight design
■ Shortened compression height
■ Reduced engine block deck height feasible
■ Thermal efficiency increase
■ Improved fuel economy
■ Material selection alternatives
In summary, these advances reinforce the expert opinion that MonoLite® steel
pistons are the technology for the future.
A New Generation of Heavy-Duty Steel Pistons
We are optimizing the potential for reducing fuel consumption and emissions.
MAHLE’s CO2 reduction solutions include downsizing technologies such as
dual-stage turbochargers and wastegate actuators. Optimized charge
exchange for increased efficiency can be achieved with our variable valve train
systems, including CamInCam® camshafts. Offering better performance, more
torque and longer service life — MAHLE enables friction reduction with our
controlled pendulum-slider oil pumps, low friction camshafts, advanced steel
piston designs and lightweight valves. The combustion process can be
improved by utilizing our rotating charge air valves and EGR valves for highly
loaded gasoline and diesel engines. While requirements are becoming
increasingly complex, our know-how as a systems’ specialist is more in demand
than ever before. MAHLE offers new solutions whenever limits are being
tightened and will continue to extend our leadership in technology.
