Diesel engine oil pressure is normal. How to adjust the oil pressure of diesel engine?

Diesel engine oil pressure is normal. Generally, the normal oil pressure of gasoline engines is 1.5-3.5, while the oil pressure of diesel engines is 3-5 in the normal range, and the idle speed is around 1. It should be noted that the oil pressure of diesel engine and gasoline engine should be divided into specific models, so the above data is only an estimate. How to adjust the oil pressure of diesel engine? Due to the wear and tear of diesel engine parts, improper assembly or other faults, the oil pressure will be too low or no pressure. Generally, diesel engines have pressure regulating valves to regulate oil pressure. On the oil filter seat, there is usually a bolt in the forward direction, which is the pressure regulating valve of diesel engine. Loosen the lock nut and turn it clockwise with a flat-head screwdriver. High oil pressure, and vice versa. But first, check what caused the low pressure. If the oil pump is faulty, the bearing clearance is too large or other faults, simple adjustment may be useless. If it is a pressure barrier caused by low oil, directly refuel. The reason why the diesel light is on. 1. The clearance of each part of the engine is too large; 2. The oil level in the oil pan is too low; 3. Oil leakage and crankshaft oil seal damage; 4. The engine water temperature is too high; 5. The engine idle speed is too low; 6. The oil used does not meet the requirements and its viscosity is too low.
