Mazda
leaning
TM
–
in
some
types
of
Mazda,
the
petrol
controller
can
(in
some
conditions)
alter
from
sequential
into
semi
‐
sequential
controlling.
It
can
be
easily
noticed
by
observing
the
LPG/CNG
injection
time
indicator
on
the
2D
map.
When
the
petrol
controller
alters
from
the
sequential
into
semi
‐
sequential
controlling
(at
the
same
load),
the
petrol
injection
time
is
reduced
by
approximately
50[%].
The
vertical
axis
indicator
(for
constant
load)
changes
its
injection
time
value
position
e.g.
from
8
[ms]
to
4
[ms].
In
the
case
of
such
a
controlling
type
in
the
LPG
mode,
“jerking”
can
occur,
resulting
from
the
fact
that
the
mixture
is
too
rich
for
the
semi
‐
sequential
mode.
In
order
to
eliminate
the
above
‐
mentioned
problems,
“Mazda
leading
TM
”
function
should
be
used.
The
weakening
coefficient
should
be
properly
set.
According
to
the
research,
its
value
should
be
approximately
17.
However,
the
value
can
be
different,
depending
on
the
engine.
The
LPG
Controller
Settings
window
lists
the
following
groups
of
parameters:
Switchover
to
gas
–
parameters
related
to
switching
from
petrol
to
LPG.
Switchover
temp.
–
LPG
pressure
regulator
temperature
required
for
the
controller
to
switch
to
LPG,
Switchover
threshold
–
engine
rpm
required
for
the
controller
to
switch
to
LPG.
For
rpm
set
to
<700,
the
controller
switches
to
LPG
at
idle
run.
Switchover
time
–
time
after
starting
the
engine
when
the
controller
can
switch
to
LPG.
Cylinder
Switchover
–
time
elapsing
between
the
switching
of
subsequent
cylinders.
E.g.
with
the
setting
at
200[ms]
for
a
4
‐
cylinder
engine,
the
switching
from
petrol
to
LPG
or
LPG
to
petrol
will
take
4*200[ms].
This
works
regardless
of
whether
the
petrol
injection
system
is
the
so
‐
called
full
sequence
or
not.
Setting
the
switching
time
to
0
will
result
in
the
switching
from
petrol
to
LPG
or
vice
versa
and
turning
on
and
off
of
the
solenoid
valves
without
any
delay.
