Mack Trucks, Inc. has introduced a new integrated engine brake, designed to deliver higher
performance than conventional engine brake technology in a lighter, more reliable package.
The new MACK PowerLeash™ engine brake is a compression release-type system that
features a hydraulic actuator incorporated into the exhaust rocker arms, and is less sensitive
to low or inadequate oil pressure than other engine brakes used on MACK engines. During
engine brake operation, the hydraulic actuators fill with oil so that the inboard exhaust valves
open as the piston approaches top-dead-center of the compression stroke. This essentially
converts the engine into a large air compressor that produces retarding horsepower to aid in
slowing the vehicle.
