[Reference]
q If a normally operating cylinder is dis-
abled, the following phenomena occur.
1) The engine speed lowers.
2) The value (quantity) of final injection com-
mand increases.
q If the engine is running near the full speed,
however, the engine speed may not lower
for the reason of engine control.
q In this case, lower the engine speed by
using the fuel control dial and judge by
increase of the injection rate command.
