What is the normal oil pressure for a 4-cylinder diesel engine?
1 Answers
Regardless of the number of cylinders, the normal operating oil pressure should be between 0.3-0.45MPa. Normal oil pressure range for diesel engines: For diesel engines, an oil pressure of 3 to 5 units is considered normal, with about 1 unit at idle. It should be noted that the oil pressure of diesel and gasoline engines depends on specific models, so the above data is only an estimate. Reasons for abnormal oil pressure in diesel engines: Due to component wear, improper assembly, or other faults, diesel engines may experience low or no oil pressure. Diesel engines are generally equipped with a pressure regulating valve to adjust the oil pressure.
