When operating the N13B16 engine, various problems can arise: engine vibration, floating speed, increased fuel consumption. Timely diagnostics and replacement of worn-out parts will increase the unit’s service life.
Motor vibrations occur when the injectors are dirty, they are checked first. When the rpm is floating, it is necessary to see if the idle valve is clean enough, and also to check the throttle valve.
With increased fuel consumption, the air flow meter is assessed – its malfunction often causes an increased gas consumption. For the N13B16 engine, it is advisable to use high quality gasoline (98th) and oil recommended by the manufacturer. The unit does not like the frequent change of working fluids.
With regular maintenance and troubleshooting, the engine will run reliably and last for a long time.
