Daewoo Novus M2SEF - Ether Start System(DDC Engine); Principle of Operation; Cylinder Replacement and Check

3-107 INSPECTION AND MAINTENANCE
Caution
1. Ether is highly flammable and explosive.
2. Do not smoke when servicing ether sys-
tem.
3. Work in well ventilated area.
4. Do not work near open flames, pilot
flames(gas or heaters), or sparks.
5. Do not carry an open flame near the ether
system if you smell ether or otherwise
suspect a leak.

23) Ether start system(DDC engine)
Ether start system is an engine starting system
designed to spray ether into the air intake system
before and after cranking at low temperatures by
means of the Electronic Control Module(ECM). In
addition, this system is actuated automatically by
the ECM and therefore, you need no special op-
eration, otherwise.
(1) Principle of operation
1) The ECM transmits electrical signal to the ether
injection relay located in the glove box near the
assistant driver's seat.
2) Then, the solenoid valve is energized to allow
ether pressurized within the ether cylinder to
spray through valve, metering orifice, tubing, and
nozzle fitted onto intake manifold.
3) If ether in the cylinder is consumed up, the LCI
on the ether injection relay lights up. At this time,
you must replace the fluid of the cylinder.
(2) Cylinder replacement and check
1) Clean all dirt from the neck of the cylinder and
top of valve before removing the cylinder. In-
stall the protective cap to protect the top of the
valve from dirt during removal.
2) Weight the cylinder to determine the amount of
fluid remaining. Subtract the empty net weight,
and convert the difference into liquid volume of
fluid remaining using 39 ml/oz weight(1.4 ml/g).

3) Ensure the cylinder is pressurized. Minimum is
120 lb/in

(827.37 kPa) at 68F(20C).
