ATLANTA, GA — Jacobs Vehicle Systems is hoping to release its next generation of the Jake Brake in 2019, the company revealed at the North American Commercial Vehicle (NACV) show.

According to Jacobs, the new High-Power Density (HPD) engine brake is the “next logical step in engine braking.”

Steve Ernest, vice president – engineering at Jacobs, said the HPD has been proven to offer twice the braking power as thecurrent Jake Brake, while working at a lower rpm range.

“It’s the next generation of engine braking, we believe,” Ernest said. “It will improve your foundation brake life, increase truck uptime and truck productivity, and increase your resale value.”

The new brake will also deliver the retarding power needed to compensate for decreasing aerodynamic drag and rolling resistance, compensate for the trend towards lower engine speeds, and and avoid downshifting during retarding.

Because the company sells predominantly to Original Equipment Manufacturers, Ernest predicted that the new engine brake will be installed on trucks made in 2019-20.

Jacobs has sold 7 million engine brakes in its history.
