Jacobs Vehicle Systems Inc. announced its Fulcrum Bridge technology is available for the off-highway market.
Fulcrum Bridge technology removes the traditional need to set and adjust the lash, or mechanical clearance in the valve train between valve and camshaft, by using hydraulic lash adjusters, according to the Bloomfield, Conn.-based company.

Hydraulic lash adjustment allows for more consistent valve motions throughout all engine operating conditions and wear over the engine lifetime, enhancing engine performance and fuel economy.
“It was previously thought to be impossible to use hydraulic lash adjusters and engine brakes together, forcing engine makers to choose between HLA’s and a Jake Brake. Jacobs’ Fulcrum Bridge system means you can have both, bringing the many vehicle performance and efficiency advantages of both technologies to off-highway operators. With the Fulcrum Bridge, the lash setting is good for the life of the engine,” said Steve Ernest, vice president of engineering at Jacobs Vehicle Systems. — Transport Topics
