Defect
On large route buses equipped with CNG engines, the fuel flow adjustment screw on the gas mixer (air-fuel mixer) is improperly adjusted, causing insufficient fuel delivery relative to the incoming air volume. This results in inadequate output under high-load conditions. In the worst case, nitrogen oxide emissions may increase beyond allowable levels.
Corrective action
Adjust the gas mixer fuel flow adjustment screw on all vehicles to the specified setting.
