THE
SMARTBRAKE IS THE
DEVELOPMENT OF A "FIXED ORIFICE" RETRO EXHAUST
BRAKE. THE "RETRO" HAS BEEN SERVING FLEETS
THROUGHOUT THE WORLD FOR MANY, MANY YEARS.
BUT TIME WAITS FOR NOBODY!
HERSHAM
HAS RECOGNIZED THIS AND SO THE RETRO HAD TO BE
UPDATED AND IMPROVED TO MEET MODERN DAY DEMANDS.
TO OVERCOME THE LOSS OF EFFICIENCY OF THE BRAKE AS
ENGINE SPEED DROPS, THE SMARTBRAKE INCORPORATES A
VARIABLE PRESSURE PLATE WHICH ONLY OPENS WHEN THE
MAXIMUM ALLOWABLE EXHAUST MANIFOLD PRESSURE IS
REACHED.
PRE-SET AT MANUFACTURE, THE BRAKE IS SET TO MEET THE
ENGINE MANUFACTURER'S SPECIFICATION. SO ALWAYS
ENOUGH, BUT NEVER TOO MUCH, BACK PRESSURE IS
AVAILABLE FOR POWERFUL RETARDATION. |
