What's wrong with the oil pressure after the overhaul of Guangkang engine?

The reason why the engine does not have oil after the overhaul: the engine oil storage is too small, resulting in no oil or little oil in the lubrication system, resulting in low oil pressure. Solution: Refueling; the oil is dirty or sticky, causing the oil pump to effectively inhale and pump out the oil, resulting in low or no pressure on the oil.

The engine oil storage is too small, resulting in no oil or little oil in the lubrication system, resulting in low oil pressure. Solution: Refueling. The oil is dirty or sticky, causing the oil pump to effectively inhale and pump out the oil, resulting in low or no pressure on the oil. Solution: Change the oil.

There are two reasons for low oil pressure. The first type is that the shaft diameter of the original camshaft (eccentric shaft) has not been ground, the bearing has not been renewed, the eccentric shaft and the eccentric tile are out of round, and the thrust shape is relatively large, so the gap is also relatively large.

This is mainly a repair quality problem.After repair, it still needs to be tested, inspected and adjusted before it can be completed and handed over. The main reasons for the above problems are: large shaft tile gap and unqualified; oil pump failure; overflow valve pressure relief; induction plug or circuit failure,...

The low oil pressure of the newly overhaul engine may have the following reasons: the internal oil duct is blocked: After the new overhaul, the oil duct inside the engine may have impurities or residues and other substances, resulting in blockage of the oil road, which in turn leads to low oil pressure.

According to the question, it means that there is organic oil pressure before the overhaul, and there is no oil pressure after the overhaul? The overhaul of the engine is carried out according to the specifications. The accessories that should be replaced have been replaced, and all the faults have been solved. There should be no oil pressure. The remaining problem is the post-repair adjustment.

How to disassemble the fuel nozzle of Guangkang electric injection engine

Remove the engine shield, remove the intake pipe, and unplug the power supply plug of the 4 fuel injectors, as well as the throttle valve and the idling motor at the same time. The fuel injector assembly bracket has two screws to fix and unscrew the left and right screws of the fuel injector assembly. Remove the assembly and take out the fuel injector.

If the fuel injector is difficult to remove, you can try the following method: use appropriate tools: make sure to use the correct tools, such as wrenches, wrenches or special fuel injector nozzle removal tools. These tools can provide better leverage and grip to help disassemble the fuel injector.

First, remove the 2 screws that fix the oil rail. Remove the intake pipe. Unplug the power supply terminals of the 4 fuel injectors,Press the card on the interface to unplug it. Note that you can't use brute force, and the throttle valve and idling motor should also be unplugged at the same time.

First, clamp the nozzle hole of the fuel injector down on the table pliers, remove the pressure control screw cap, pressure regulation screw and spring, and clean it. Then fix the fuel injector head on the table clamp, loosen the coupling fastening nut, remove the fuel injector coupling, and carefully check it after careful cleaning.

How does Guangkang engine time

Look in front of the engine. The standard value of the intake valve gap is usually 0.20 - 0.25mm. From the front of the engine, the timing pit of the crankshaft pulley is aligned with the timing mark.

Oil pressure regulator failure: There is usually an oil pressure regulator in the engine to control the oil pressure. If the regulator fails, it may cause abnormal oil pressure. The oil pressure regulator needs to be checked and repaired. Oil leakage: After overhaul, oil leakage may occur, resulting in a drop in oil pressure.

The Guangkang electric injection engine can start without being installed in the car. If the car is not installed and ignited, there should be a corresponding model of full-car cable, and motorcycle electrical appliances should be connected.When the engine is removed and ignited, it is undoubtedly just the connection of the ignition circuit. Other lines such as headlights, horns, etc. do not need to be connected.

A few mainframe engines are imported from the United States. The product research and development department of Liugong has been rated as a national enterprise technology center, and a postdoctoral workstation has been established. It has more than 500 engineering and technical personnel engaged in product design and manufacturing technology research, so that the product research and development level and technical performance have always maintained a leading position in the industry.

The valve gap of the diesel engine is 0.25-0.30mm, and the gap of the exhaust valve is 0.30-0.35.

This problem is generally caused by the following points: the transmission pressure is too low, or the pressure relief causes insufficient pressure, the clutch slips; the torque converter is seriously worn, or the transmission oil viscosity is too high.
