Power management company Eaton last week showcased 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 benefits that include fuel economy, improved engine performance and improved braking and safety.
Eaton’s decompression engine brake for heavy-duty applications (shown) 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. 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 for 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, consistent combustion, low service costs, improved dynamics and compatibility with variable valve actuation.
