Smoke emission and solution technology while the engine is running

After the tractor has been driving for a certain period of time, due to overloaded, over-speed transport, improper use of engine parts, exhaust pipe carbon deposition, etc., resulting in the engine running black smoke, blue smoke, white smoke phenomenon. As the fuel consumption rate increases, the power of the engine decreases, affecting the normal operation of the engine and reducing the owner's operating income.
I. Causes and Solutions to Black Smoke Produced by Badly Exhausted Engine Exhaust Pipes
1. Causes of black smoke: The tractor is overloaded with overspeeding operation, causing heavy engine load and serious carbon deposit in the combustion chamber; the fuel supply time is too late and the combustion is incomplete; the injector is not working properly; valves, cylinder liners, pistons and pistons Ring wear leakage; excessive fuel supply, diesel quality does not meet the requirements; intake and exhaust pipe blockage, resulting in insufficient intake, exhaust gas exhaust.
2. Solution: Reducing the load, carrying out transport operations according to the approved loading capacity for the license plate, and removing the coke from the combustion chamber; increasing the gasket of the fuel injection pump so that the oil supply advance angle meets the requirements; removing the carbon deposit of the injector, adjusting Injection pump pressure or replacement of a new outlet valve; grinding valves, repair or replace cylinder liners, pistons, piston rings; adjust fuel supply to oil pumps, replace fuels that meet regulations; clean air cleaners and remove muffler carbon deposits.
Second, the cause of engine exhaust blue smoke and solutions
1. The cause of blue smoke: The oil enters the combustion chamber to take part in the combustion. The piston ring and the cylinder sleeve are not completely run in. The engine oil enters through the gap; the piston ring is glued in the groove, and the piston ring's taper surface is reversed and the oil is lost. Role; piston ring wear excessive, oil running into the combustion chamber from the open gap; oil sump oil surface is too high; too much air filter oil; valve and duct wear, clearance is too large.
2. Solution: The new car or the overhauled locomotive must be adjusted to the engine according to the regulations so that the parts can be meshed properly; see the assembly mark, install the piston ring correctly; exchange qualified or enlarged size of the piston ring; check the oil pan The cause of the rise in oil level is to release excess oil in the oil pan; reduce the oil in the filter oil pan; replace the valve guide.
Third, the engine exhaust pipe caused by white smoke causes and solutions
1. The cause of white smoke: poor atomization of the fuel injector or dripping oil to make some diesel fuel incombustible; there is water in the diesel fuel; the cylinder head and cylinder liner have cracks that are invisible to the naked eye, and the cylinder head gasket is damaged to make water in the cylinder. The temperature is too low.
2, take the white smoke solution: clean or replace the injector, adjust the fuel injection pressure; remove the water in the tank and the oil, do not buy low-quality bad oil; replace the cylinder head gasket, cylinder liner, cylinder head; run after a period of time eliminate.
