WG/DF1005
11
WG/DF1005 New Components Design

• Distributorless Ignition System
• Combustion Chamber Design

12
WG/DF1005Distributor-less Ignition
One Ignition Coil per Cylinder
Ignition Trigger
Ignition Module
Do not mount on radiator or any source of
vibration
13
Ignition System Trigger
Ignition trigger is a magnetic sensor with Signal
Rotor. Signal Rotor is mounted on fuel
injection gear in place of transfer pump
eccentric
14
Distributor-less Ignition
Ignition Module uses wave form from pickup coil
to determine the position of the crankshaft and
the speed of the engine. Adjustment of the
ignition timing from standard advance is
determined by the speed of the engine. Over-speed
prevention is also controlled by module
15
DF1005LPG Regulator
LPG Regulator
Do not mount on radiator or any source of
vibration, make sure LP fuel line between
regulator and carb is correct length.

WG/DF1005Combustion Chamber
This new combustion chamber design is used on the
DF1005 as well. Lower spark plug improves
emissions
