Table 5-1(continued)
Common Faults Possible Causes Fault Inspection and Treatment
3. The exhaust
pipe blasts
2. The natural gas supplied is overthick or
overthin (the pressure reducer works
improperly)
Check the oxygen sensor and gas
metering valve.
3. Overlarge phase difference in ignition
advance angle.
Check the ignition advance angle by
ignition rob and the clearance between
phase sensors.
4. The engine is
under-powered
1. The manual valve on natural gas bottle is
not fully opened.
Check the gas bottle.
2. The gas pressure is too low.
Check whether the pressure reducer, gas

1, 2, 3 and 4 above.
6. The gas
consumption is
large
Carry out an overall inspection in accordance with the troubleshooting methods for fault
1, 2, 3, 4 and 5 above.
