Why is the engine smoking? ? ? ? Don't worry, please let me go over your forklift with you.
Reason 1-1: Black smoke from the exhaust pipe (due to poor combustion)
——————Partially closed choke valve
Troubleshooting method: Adjustment
Reason 1-2: Black smoke from the exhaust pipe (due to poor combustion)
——————Air filter blocked
Troubleshooting method: Cleaning and dredging
Reason 2-1: White smoke from exhaust pipe (due to engine overcooling)
——————Not enough engine warm-up
Troubleshooting method: Increase the load if the engine warm-up is not enough, and then gradually increase the load after the engine is warmed up to a water temperature above 50 degrees
Reason 2-2: White smoke from the exhaust pipe (due to the engine being too cold)
——————Gasoline contains water
Troubleshooting method: Remove moisture
Reason 2-3: White smoke from the exhaust pipe (due to the engine being too cold)
——————Water in cylinder
Troubleshooting method: Troubleshooting
Reason 2-4: White smoke from the exhaust pipe (due to the engine being too cold)
——————Poor atomization of fuel injection of the fuel injector, oil dripping phenomenon, and low fuel injection pressure
Troubleshooting method: Check the oil nozzle assembly
Reason 2-5: White smoke from the exhaust pipe (due to the engine being too cold)
——————The fuel injection time is too late
Troubleshooting method: Readjust the oil supply time
Reason 2-6: White smoke from the exhaust pipe (due to the engine being too cold)
——————The pressure in the cylinder is not enough, the fuel is not burned well and is excluded
Troubleshooting method: Check cylinder pressure
Reason 3-1: Blue smoke from exhaust pipe (due to burning of organic oil)
——————Too much oil
Troubleshooting method: Release excess oil
Reason 3-2: Blue smoke from exhaust pipe (due to burning of organic oil)
——————The piston ring wears too much, or is stuck by carbon deposits, causing oil to overflow
Troubleshooting method: Replace or clean piston rings
Reason 3-3: Blue smoke from exhaust pipe (due to burning of organic oil)
——————The gap between the piston and the cylinder is too large
Troubleshooting method: Overhaul or replacement
Reason 3-4: Blue smoke from the exhaust pipe (due to burning of organic oil)
——————Long-term low load (less than 40% of the rated power) far transfer
Troubleshooting method: Appropriately increase the load
Reason 3-5: Blue smoke from the exhaust pipe (due to burning of organic oil)
——————Air filter clogged
Troubleshooting method: Disassemble and clean the air filter
Reason 3-6: Blue smoke from the exhaust pipe (due to burning of organic oil)
——————The gap between the valve push rod and the valve guide is too large
Troubleshooting method: Replace
