Magnum Monosteel®: Providing Fuel Economy and Reduced Emissions for Heavy-Duty Vehicles |
The next-generation Monosteel piston, known as Magnum Monosteel®, addresses the increasing thermal, mechanical, abrasion and corrosion challenges placed on heavy-duty diesel engines resulting from stringent emissions regulations. The Magnum reduces piston mass by up to seven percent and also includes design features that reduce friction for improved fuel economy and lower emissions.
Magnum’s key differentiator is its unique double-band piston skirt design, a first for modern diesel pistons. The double-band skirt helps to reduce frictional drag and reduces the overall area piston skirt area by 40 percent, making this innovative design feature the primary contributor to the Magnum’s friction and mass reduction. Additionally, extensive engine testing has shown piston friction reduction of 17 percent, compared to conventional steel piston designs.
