| 摘要 |
A method of controlling the operation of a fuel metering unit of the type incorporating a metering valve (12) and a temperature sensor (30) is disclosed, the method comprising the steps of:
sensing a change in temperature;
using the sensed change in temperature to derive a fast temperature correction factor (36c);
using the sensed change in temperature to derive a slow temperature correction factor (38c);
using the fast and slow temperature correction factors (36c, 38c) in combination with a fuel demand (34a) to determine a metering valve position; and
moving the metering valve (12) to the determined metering valve position. |
