INNOVATIVE CYLINDER LINER TECHNOLOGY FROM FEDERAL-MOGUL REDUCES ENGINE OIL CONSUMPTION BY UP TO 40 PERCENT
(Thomson Reuters ONE) -
Hybrid Liner design helps meet new challenges of downsized diesel and gasoline
engines
Friedberg, Germany, May 17, 2012 . Federal-Mogul Corporation (NASDAQ: FDML) is
increasingly using a dual-material cylinder liner technology to reduce bore
distortion and improve function in the latest generation of lighter, highly-
loaded gasoline engines. The company's patented Hybrid Liner technology provides
reliable, cost-effective, long-term performance while reducing engine oil
consumption, especially in high-output aluminium engines with small interbore
bridges and weight optimized designs.
"Federal-Mogul is helping engine manufacturers to increase the power output and
durability of smaller engines, supporting them in a key area of their global
CO(2) reduction strategies," said Gian Maria Olivetti, Federal-Mogul's vice
president for Technology and Innovation, Powertrain Energy. "Cylinder bore
distortion is one of the main factors limiting increases in power and torque
outputs, particularly in lightweight aluminium cylinder blocks. Our patented
Hybrid Liner increases the strength and stiffness of the combined block and
liner assembly, allowing significant weight reduction without compromising
engine performance and durability."
Federal-Mogul's Hybrid Liner integrates the liner into the aluminium block
casting more effectively than alternative technologies, both structurally and
thermally. It comprises a conventional cast iron sleeve with an aluminium
coating applied to the exterior through a proprietary process. The cast iron
sleeve provides good tribological properties and is compatible with cost-
effective ring packs.
The outer surface of the liner is manufactured to provide a surface topography
that is conducive to mechanical interlocking with the aluminium block material.
The liner coating is an AlSi12 alloy with a melting point below that of the
aluminium engine block, which provides outstanding intermetallic bonding between
the surfaces of the two materials. To meet the cost and robustness requirements
of series production, the coating is applied in a process that uses advanced
wire arc thermal spray technology to ensure that coverage, thickness and bonding
strength are uniform around the complete height and circumference of each liner.
The coating surface roughness is also controlled, to provide undercuts and
micro-porosities so that an extremely strong, intermetallic transition zone is
formed between the coating and the block casting material.
"Compared to alternative technologies, the Hybrid Liner reduces bore distortion
in a running engine by two-thirds," said Olivetti. "Maximum second order bore
distortion can be as low as 11 percent of that experienced by corresponding
cast-in liners, while the cylindrical distortion under operating loads is up to
three times better. As a result, oil consumption is reduced by up to 40
percent."
Federal-Mogul's Hybrid Liner also results in up to 30 percent higher heat
transfer rates, reducing the cylinder wall temperature by up to 40°C (104°F)
compared to alternative designs. Dynamic strength increases as well; in a cyclic
pulsing pressure test, the Hybrid Liner showed no failure at pressures of up to
200 bar, whereas a standard liner block design cracked at 100 bar.
"Federal-Mogul's Hybrid Liner also allows engine manufacturers to improve
packaging by reducing the distance between adjacent cylinders; pressure die-cast
engine blocks with Hybrid Liners can have a material wall thickness of just 3mm
between the bores," Olivetti added. "If a water channel is drilled between two
cylinders, the Hybrid Liner technology limits the formation of cracks, allowing
coolant to penetrate only as far as the liner coating. Conventional liners can
allow water to seep down the joint between liner and casting, reaching the
crankcase and contaminating the lubricating oil."
Federal-Mogul's Hybrid Liner is produced at its Powertrain Energy manufacturing
facility in Friedberg, Germany. The technology was a finalist in the 2012
Automotive News PACE Awards.
