The common faults of 1KZ-T 3.0 diesel engines are:

Diesel engines can let us have enough power, a lot of people who like off-road cars must be more like it, but diesel cars are not as bad as we imagine. What are the common failures of diesel engines? This is when we are driving, we must pay attention to, or we must have safety hazards when driving, if there is a failure, delay is our own time.
Diesel engine common faults: no idle engine, cause: governor idle spring is too soft or broken. Governor sensing element is worn too much. The plunger wear of fuel injection pump is serious. The temperature is too low. Procedure The cylinder pressure is too low.
Diagnosis and treatment: There is no idle speed during cold start, which is normal. This is because the temperature is too low, oil viscosity is too large, so that the engine resistance increases, diesel spray, evaporation conditions become poor, resulting in the engine can not maintain the lowest stable speed operation, when the throttle is raised, it will soon flout. In this case, the throttle can be adjusted to run slightly above the idle speed, and the idle speed can be resumed after the standby engine heats up. If the engine has been used for a long time, no idle working condition, and accompanied by insufficient power, fuel consumption is not normal, generally due to excessive piston wear, idle oil leakage increase, so that the oil supply can not meet the requirements of idle working condition, or cylinder pressure is too low, injection advance Angle is too large, too small, so that the engine combustion conditions are poor. As long as the failure of underpower is handled, idle condition will naturally resume.
If the above conditions are normal, the idle speed working elements of the governor should be considered. Check whether the spring of the governor is broken, or the wear of the governor element is too much or the spring is too soft, so that the centrifugal force of the flying hammer in idle operation is far greater than the tension of the spring and the oil is reduced, or the maintenance personnel adjust improperly. The fuel injection pump assembly must be removed and re-repaired on the test bench. When checking the governor, the first adjustment should be made through idle screw, if the adjustment is ineffective, then adjust the idle spring pretension. The idle spring adjustment nut can be slightly twisted inward or gaskets can be added to the spring seat to increase the preload and idle speed. If the spring is broken, it should be replaced and then adjusted to restore idle performance.
Engine oil pressure is too low, the cause of failure: crankcase oil level is too low or no oil; Engine coolant temperature is always maintained at a higher temperature value, resulting in low oil viscosity; Oil pressure sensor failure or sensor signal may short circuit to the ground; Oil filter blockage, resulting in insufficient oil supply; The viscosity level of the lubricating oil used does not meet the requirements of the use environment; Other faults.
Troubleshooting: Check the scale of the oil scale, ensure that after 5 minutes of shutdown, the oil level between the L and H level of the ruler near the H level is full oil level, if not enough, please add the same type of oil to the specified scale; Ensure that the coolant temperature is within a normal range according to the treatment method of excessive starting coolant temperature; Check the wiring on the pressure sensor to ensure that the connection is firm and reliable. Record the resistance and pressure display value of the pressure sensor under the boot state and compare it with the table below. If there is a large difference, please replace the pressure sensor. Replace the oil filter; Check the technical specifications of the oil and replace the oil according to the climatic conditions; If all the above faults are rectified and the engine oil pressure is still low, contact the generator manufacturer.
3, the engine smoke white cause of failure: the engine cylinder temperature is too low; The oil tank is placed too high, the highest oil level is 1.5 meters above the engine pump; Fuel quality is poor, water content exceeds the standard; Valve and injection timing is not correct; The injector needs to be adjusted. Treatment method: Check the engine water temperature, turn on the engine water heater or run in no-load (or low load) for 10-15 minutes, when the water temperature rises to 50-60℃, the exhaust smoke will gradually return to normal. Lower the height of the engine fuel tank or oil level to ensure that the difference between the highest oil level of the fuel tank and the height of the engine oil pump is within 1.5 meters to prevent high oil pressure resulting in the accumulation of fuel in the engine combustion chamber, resulting in incomplete combustion and white smoke.
Diesel engine deflagration, diesel engine deflagration, cylinder pressure suddenly increased, the piston violently hit the cylinder liner, causing a lot of metal knocking sound and vibration. Solution: check and adjust the oil supply advance Angle. If the oil supply advance Angle is too large, the piston will inject too much diesel oil near the top dead center, causing the diesel pressure to rise rapidly and hitting the cylinder liner violently when the piston goes down. Check the quality of diesel oil. If the quality of diesel oil does not meet the national standards, the flammable composition is too much, which will cause deflagration when diesel oil is injected into the cylinder, resulting in excessive increase of pressure in the cylinder and cause piston knocking. Check the diesel engine overheat operation time, diesel engine overheat operation for a long time, the combustion chamber temperature is too high, diesel injection evaporation too fast, combustion speed too fast, pressure rise too fast, resulting in deflagration. Remove carbon accumulation, diesel engine cylinder liner, piston carbon accumulation in excessive compression ratio is too high, cause deflagration.
Diesel vehicle processing general method - winding binding method, diesel fuel oil is divided into low pressure oil road and high pressure oil road, the two kinds of oil road in the low pressure tubing and high pressure tubing leakage, can take the "winding binding method" emergency repair. When the low-pressure tubing leaks, grease or oil-resistant sealant can be applied at the leakage place, and then the tape or plastic cloth is wound in the smear, and finally the tape or plastic cloth with metal wire will be wound tightly; When the high pressure tubing leakage or concave is serious, the leakage or concave can be cut off, with rubber hose or plastic pipe it is connected to the two ends, and then tied with a fine wire; When air leakage occurs at the hollow bolt of the high-pressure tubing joint or low-pressure tubing joint, cotton thread can be wound around the high-pressure tubing joint or hollow bolt, and grease or oil-resistant sealant can be applied and tightened.
