Magnum Monosteel® Piston

The next-generation of the award-winning Monosteel® piston, Magnum Monosteel®, reduces piston mass by up to seven percent and includes key design features that reduce friction for improved fuel economy and lower emissions.

Key features include:

• Double-band piston skirt design, a first for modern diesel pistons
• Dual friction-welded construction, enabling large cooling galleries for high temperature resistance and strength
• Friction reduction of 17 percent, when compared to conventional steel piston designs

Monosteel® Pistons

The Monosteel Piston’s friction-welded, single-piece construction requires no fabrication and no assembly.

Features of the Monosteel Piston include:

• A large, closed structural gallery with superior bowl rim and ring groove cooling, reducing groove distortion and improving oil control and gas sealing
• A profiled, bushingless pin bore
• A full-length skirt for stable piston dynamics, reducing risk of liner cavitation and improving ring sealing
• Process allows material flexibility with crown material options to reduce corrosion or oxidation, and/or skirt material options to improve manufacturability.

The Monosteel Piston’s inertia-welded steel forging provides strength and enhanced cooling performance for heavy-duty and industrial markets. It has a 250-bar and beyond firing pressure design capability, which meets Euro V and U.S. 10 emissions regulations, and an induction-welded design that brings lightweight steel pistons to the mid-range diesel category.

Aluminum Diesel Pistons

Federal-Mogul aluminum diesel pistons are gallery-cooled, designed with the latest technology and best-in-class architecture for both light and heavy-duty vehicles.

• Federal-Mogul’s optimized gallery locations for maximum cooling can result in up to a 10 percent lower bowl rim temperature.
• Advanced side-casting techniques significantly improve structural stability (even with thin wall designs).
• Restructuring of the combustion-bowl rim and bowl base can provide up to a 100 percent increase in fatigue life.

Aluminum Gasoline Pistons

Federal-Mogul’s aluminum gasoline pistons provide innovative solutions today for tomorrow’s challenges in light-vehicle gasoline and high-end gasoline engines. Features of these pistons include:

• A patented Elastoval™ skirt for the highest strength-to-weight ratio
• A range of proprietary high-temperature alloys including FMB2
• EconoMiser™ piston technology with up to 20 percent lower friction
