The gas injection is controlled by two valves in
series. The window valve sets up a timing window
within which the gas injection can be performed,
and also limits the maximum injection. The gas
injection valve controls the precise timing and gas
injection amount.
The gas injection valve and the window valve are
both controlled by the GI control system and the
GI safety system respectively, as is the case for
several other systems, see Fig. 16.00.02.
