What is the reason for the diesel heater smoking and failing to start?

[StIsabella]

The reasons for the diesel heater smoking and failing to start are as follows: Poor ventilation: It may be due to poor ventilation affecting the startup. You can improve the ventilation system and appropriately increase the vent size. Poor fuel quality: It may be due to carbon buildup in the truck's diesel heater combustion chamber. Open the diesel heater and clean the carbon deposits. It could also be caused by poor fuel quality affecting ignition. You can have it specifically tested at an after-sales repair shop. Working principle of diesel heaters: The general principle of a diesel heater is that it is a small internal combustion engine that directly burns diesel to obtain heat, and then uses the machine's heat dissipation to warm the driving compartment.
