FULL NAME | PUMPDOZER 450 |
DESCRIPTION
It is intended for automatic control of fuel supply into engine AI450 by two basic channels of an electronic control system and fuel dozing into the engine proportionally to a location of the engine control lever in reserve hydromechanical control mode.
Pumpdozer provides:
- increase of fuel pressure in pumping stage of pumpdozer;
- Increase of fuel pressure In main stage of pumpdozer;
- fuel supply to startup engine nozzles;
- fuel supply to operational engine nozzles;
- engine turnoff: mechanical or by electric command;
- fuel filtration;
- signalization of pressure drop in fuel filter;
- limitation of minimum and maximum fuel consumption;
- fuel dozing by electronic regulator command during operation of the main control system;
- transition to reserve control system by electric command;
- throttle characteristic GT =f (α руд) during operation of reserve control system;
- characteristics of acceleration and release GТ =f (t) during operation of reserve control system.
