BLOOMFIELD, CT, USA − Jacobs Vehicle Systems®, a worldwide manufacturer of engine retarding and valve actuation systems for the commercial vehicle industry, is currently celebrating the company’s 60th anniversary.
"Until now, hydraulic valve lash adjusters could not be used in heavy-duty diesel engines in combination with an additional engine brake, as the engine brake causes significant valve lash during the braking process. The hydraulic compensation elements automatically readjust to take up this play, thereby preventing correct seating at the end of the cycle.
Fleet Equipment's Alex Crissey spoke with Robb Janak, director of new technologies at Jacobs, on the Fleet Future podcast to discuss upcoming emissions regulations and the technologies Jacobs has developed to meet them. Listen to the episode: The Impact of Emissions Standards on Trucking Equipment
