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
