Eaton Showcasing Advanced Valvetrain Technologies at IAA, including Hydraulic Lash Adjuster and Engine Brake

Date: September 21, 2016

HANNOVER, GERMANY… Power management company Eaton is showcasing its complete portfolio of Advanced and Standard Valvetrain solutions – including Variable Valve Lift for both diesel and gasoline engines, Cylinder Deactivation, Hydraulic Lash Adjusting and Decompression Engine Brake – at the 66th IAA Commercial Vehicle Show. The technologies provide customers with a range of benefits – from fuel economy and improved engine performance, to improved braking and safety.

Eaton’s Decompression Engine Brake for heavy-duty applications is a valvetrain system solution that can enhance braking by enabling the valvetrain to switch between driving mode and engine braking mode, with the potential for incorporating advanced Variable Valve Actuation solutions (e.g. Miller/Atkinson). Eaton’s technology can perform at lower engine speeds better than competitive offerings and can be integrated into a standard assembly.

“With Eaton’s expertise in valvetrain technologies, we are able to apply our knowledge and truly maximize the braking power of a commercial vehicle to deliver better braking and more efficient use of the power being generated,” said Gerard Devito, chief technology officer, Eaton’s Vehicle Group. “Our Engine Brake technology is part of Eaton’s much broader variable valve actuation strategy, which allows us to look at the complete system more thoroughly than others who do not possess the expertise we have in this area.

Eaton also is displaying a series of Hydraulic Lash Adjusters (HLA), which are specifically designed to automatically adjust the lash in the valvetrain, ensuring precise valve seating and optimized engine air flow and fuel management. Eaton’s HLA’s are designed for heavy- and medium-duty engines, can be used with diesel and natural gas applications, and can be engineered for use in combination with Eaton’s variable valve actuation technologies.

Benefits of Eaton’s HLA’s include:

• Noise Reduction -- dramatically reducing the noise caused by rattling valvetrain components and high valve closing velocities.
• Consistent Combustion -- by enabling consistent lash throughout the life of the engine, consistent combustion is achieved.
• Low Service Cost – service costs are lowered because the need to set the lash is eliminated.
• No need to disassemble the cylinder head to set the lash on off-highway vehicles when service may be required at the work site.
• Compact Packaging -- by eliminating the need to access the rocker cover to set the lash, engine packaging is enhanced.
• Improved Dynamics (stability) -- Hydraulic lash adjusters  improve dynamic behavior by lowering valve seating velocities.
• Compatibility with Variable Valve Actuation -- Eaton’s HLA design can be engineered to be used in combination with Eaton variable valve actuation technologies.

Eaton is a power management company with 2015 sales of $20.9 billion. Eaton provides energy-efficient solutions that help our customers effectively manage electrical, hydraulic and mechanical power more efficiently, safely and sustainably.
