APM Fuel type Speed Governor is a fuel based electronic road speed limiter. This smooth operating device increases engine life, fuel effciency, and reduce maintenance cost of your vehicles.
The speed sensor is connected to the gearbox and it will detect the speed and
send inputs to the Electronic Control Unit (ECU). The ECU constantly compares
this speed signal to the set speed range.
The Fuel Control Unit (FCU) is connected between the fuel filter and fuel pump.
The FCU is controlled by the ECU which monitors fuel usage.
This ensures that engine is not starved at all times. Even when the solenoid is closed, a certain amount of fuel rows to the engine through the bypass valve. By doing this, the fuel consumption and the speed of the vehicle can be controlled
Electronic Control Unit (E.C.U) ECU is a microprocessor based controlling device, which constantly monitors the vehicle speed and sends signals to the Control Unit accordingly.
Speed Sensor / Speed Adaptor
Speed sensor is a square wave pulse generating equipment atted to the gearbox
output.
Fuel Control Unit (F.C.U)
FCU is a solenoid valve mechanism which will operate according to the pulses or
inputs from the ECU.
Based on the inputs, the ECU closes the solenoid valve thereby reducing the fuel to the engine and hence the speed.
