Why YOU need it.

• Because if you drive sensibly, any vehicle uses
  less fuel and will last longer !!

3
Why YOU need it (continued...)

• Why should your drivers waist your money and
  wreck your vehicles ??

4
Why YOU need it (continued...)

• By controlling the maximum speed and maximum
  engine revs of your vehicles, YOU WILL SAVE
  MONEY, because your vehicles will be more
  economical on fuel and will last longer.

What our clients say.

• "We find the system very effective for the
  control of vehicle speed and engine revs. We are
  confident that the Safe Rider Speed Limiter is
  worth more than it's money." Vehicle Fleet
  Manager, Kruger National Park.
• "Reports indicate that the system works well,
  with both rpm and vehicle speed staying at, or
  within set parameters. It is apparent that the
  device works successfully." National Technical
  Manager, Super Group.

6
What our clients say (continued)

• "We have found that our fuel account has
  decreased by approximately 30. Our accident
  rate has also decreased drastically." Jaco
  Geldenhuis, Group Transport Manager, Profurn
  Group
• "This is the route we recommend. The governor of
  a mechanical injection pump is designed to
  control engine speed, delivered quantity and
  engine torque compensation. By controlling the
  throttle lever movement, these functions are not
  interfered with." Dave Stalker, Technical
  Services Manager, Robert Bosch (Pty) Ltd.

TECHNICAL SPECIFICATIONS AND CHARACTERISTICS
(continued)

• Operating characteristics
• Pre-warning buzzer alerts the driver when he is
  approaching the maximum set speed.
• Speed limiting operation is smooth and allows for
  stabilised speed.
• Does not interfere with the vehicles braking
  system.
• Does not affect the vehicles road speed or
  engine power output when the vehicle is running
  at or below the set maximum limits.
• Allows normal accelerator control for the purpose
  of gear changing.
• No form of malfunction will result in an increase
  in engine power above that demanded by the
  position of the accelerator pedal.
• The speed limiting action is not affected by the
  position of the accelerator pedal.
• All components necessary for the limiting
  function are at all times energised while the
  vehicle is operating.
• The limited levels remain constant under all
  climatic conditions.
•        

14
TECHNICAL SPECIFICATIONS AND CHARACTERISTICS
(continued)

• Response tolerances on a level road (gradient
  less than 2) with neutral wind conditions
• The vehicle speed will not exceed the set speed
  by more than 2.
• Under continuous full throttle load, the vehicle
  will be able to accelerate with maximum engine
  power up to the set limits and will stabilize on
  the limits immediately upon reaching it.
• This stabilised speed will not vary by more than
  2.
• On petrol driven engines the unit will not cause
  back firing due to accumulated unburned fuel
  mixture in the exhaust system.
•  
• 6. Different methods used to reduce engine power
  when the set limits are reached
• 6.1 Petrol driven engines Either of the
  following
• Fuel injected engines By controlled
  interruption of the power circuit to the
  electrical fuel pump.
• Carburetor engines By controlled interruption
  of the ignition spark.

15
TECHNICAL SPECIFICATIONS AND CHARACTERISTICS
(continued)

• 6.2 Diesel engines Either of the
  following
• By controlled interruption of the electrical
  circuit which energizes the fuel governor in the
  injector pump.
• By employing a pneumatic actuator, comprising an
  air cylinder, fitted into the accelerator
  linkage/cable, which is opened and closed by the
  central microprocessor via an air valve. The air
  cylinder will either extend or shorten the total
  length of the accelerator linkage (depending on
  the design of the engine), to move the
  accelerator lever on the engines injector pump
  in the decelerate direction. The motion of the
  air cylinder is controlled by an airflow control
  valve, fitted in the air supply line to the air
  cylinder. The effect is a smooth operation,
  which cannot cause any harm to the engine, the
  transmission or the drive train. This method is
  the approved by Robert Bosch Ltd, the worlds
  leading manufacturer of diesel injector pumps.
• By controlled restriction of the fuel flow to the
  injector pump, by means of a fuel solenoid valve.
