CNG Emulator must be connected to the oxygen sensor, and test whether it is normal emulation. Many refitting factories have irregular processes, no wiring or incorrect simulation settings, and even give wrong explanations such as "It is normal for the natural gas burning fault light to turn on."
The wiring method of the CNG Emulator is to disconnect the signal wire of the oxygen sensor, connect the sensor with the white wire of the emulator, and connect the yellow wire to the trip computer input.
After the wiring is completed, be sure to measure the DC voltage between the yellow wire and the ground under the two states of oil burning and gas burning. The DC voltage between the yellow wire and the ground is 10s and fluctuates about 8 times at 0-1v, to judge whether the simulator is through and the gas burning simulation signal It's not normal. If this is not the case, you can debug DIP switches and potentiometers as follows.
A natural gas vehicle is a gas-fueled vehicle that uses natural gas as fuel. The methane content of natural gas is generally above 90%, which is a clean automobile fuel.
The LPG CNG Switch also has its debugging method before using it, and it also needs to be debugged.
