Allied‑Signal 06848 441794 Fuel Control Assembly Unit

Module Feature

06848 441794 is Allied‑Signal main fuel control assembly, model CJ‑ACL aviation fuel control unit. It is an aircraft engine core hydraulic‑mechanical fuel metering component. The commodity status is "as‑is", belongs to second‑hand aerospace spare part, no performance guarantee.

Working principle

Realize mechanical‑hydraulic closed‑loop adjustment according to engine rotor speed, pressure and temperature signal. Accurately measure and supply fuel flow to the aero‑engine combustion chamber, maintain stable engine operating state under different flight conditions.

Onboard components

Fuel metering valve assembly, pressure compensating mechanism, hydraulic servo piston, spring diaphragm unit, fuel inlet‑outlet port, mechanical adjustment screw, aluminum alloy housing.

LED indicators

No onboard LED indicators. Working condition is judged by engine parameter data of aircraft host system.

Hardware self‑diagnosis

Detect fuel flow deviation, pressure loss, internal leakage, stuck valve element through aircraft engine monitoring system; disassembly inspection for internal component wear.

Programming software

No configuration software, pure mechanical‑hydraulic fuel control component.
