It has
been mentioned
that the
djesel
engine
sensitively
responds
to
changes
of the
start
of
injection.
The
beg'inning
of
del'ivery
strongly
influences the
efficiency
of the
diesel
engine. For example,
if
you
have
a
passenger-vehicle
diesel-engine
of
60
kW
and the
beginning
of
delivery
is
changed
by
only 3 degrees
crank
angle, the
power
drops 6 kW,
the torque
9
Nm
and
the
smoke
blackening
rises
