Analysis of abnormal noise during diesel engine operation

When the diesel engine is operating abnormally, abnormal noises usually occur. Usually, you can know whether the diesel engine is malfunctioning by "auscultating" the diesel engine. If you hear abnormal noise, you should immediately stop the engine and inspect the diesel engine. Ming reason.

1: Diesel engine injection time is too early or too late: rhythmic crisp metal knocking sounds or low and unclear knocking sounds should be adjusted at this time;
2: The wear of the connecting rod bearing bush makes the fitting clearance too large: When running, you can hear the impact sound of the parts in the crankcase, and you can hear the heavy and powerful impact sound when the speed of the diesel engine is suddenly reduced. In this case, the bearing bush should be disassembled and inspected. Necessary Should be replaced when
3: The piston pin fits too loosely with the connecting rod small-head bushing hole: there is a light and sharp sound when the diesel engine is running. This kind of sound is especially clear when running at constant speed. Replace the connecting rod small-head bushing so that it is within the specified clearance range. Inside;
4: The gap between the piston and the cylinder liner is too large: When the diesel engine is running, an impact sound is heard on the outer wall of the cylinder. When the speed is increased, the noise is increased. At this time, the piston should be replaced or the cylinder liner should be replaced according to wear and tear.
5: Diesel valve spring is broken, tappet is bent, and push rod sleeve is worn: A slight rhythmic tap sound is issued throughout the cylinder. At this time, you should check the diesel engine parts and replace damaged parts, and correct the valve clearance;
6: The radial clearance of the crankshaft rolling main bearing is too small: the diesel engine makes a particularly sharp sound during operation, and the sound is clearer when the throttle is increased; the crankshaft rolling main bearing's radial clearance is too large: a "huohuo" sound is issued during operation. Should check the rolling main bearing when there is noise, replace it if necessary;

7: The front and rear thrust bearings of the crankshaft wear, and the axial clearance is too large to cause the crankshaft to move forward and backward: When the diesel engine is running, you hear the collision sound of the crankshaft moving forward and backward. At this time, you should check the axial clearance and the degree of wear of the thrust bearing. It is necessary Replacement
8: The inorganic oil between the rocker adjusting screw and the spherical seat of the putter. When the diesel engine is running, abnormal noises are analyzed. A "squeak" sound from dry friction is heard at the cylinder head. At this time, the cylinder head cover should be removed. Fill with engine oil;
9: There is abnormal collision noise when the turbocharger is running. At this time, it should be disassembled to check whether the bearings are worn, and whether the blades of the impeller are bent. At the same time, measure the abnormal noise and analyze the gap when the main diesel engine is running, and make adjustments and replacements. Damaged parts, cleaning the oil filter of the supercharger, and the oil inlet and outlet pipelines, to ensure that the abnormal noise during the operation of the diesel engine is analyzed, and the lubricant is unblocked.
10: The valve hits the piston: The cylinder head emits a heavy, even, rhythmic tapping sound during operation. Holding the nut of the cylinder head cover with your finger has a feeling of collision. Remove the cylinder head cover and check for collision. Reasons, adjust valve clearance, check abnormal noise when the diesel engine is running. If necessary, analyze whether the piston model is adjusted correctly. If there is a collision, you can dug the valve recess or add a sheet with a thickness of 0.2.mm or .0.40mm. The same copper gasket on the bottom of the cylinder;
11: The gap between the intake and exhaust valves is too large: when the diesel engine is running, abnormal noises are heard. A loud rhythmic sound is heard at the cylinder head. At this time, the valve gap should be recalibrated.
12: The transmission gear is worn and the gap is too large: abnormal sounds are made at the front cover. When the diesel engine suddenly drops speed, an impact sound can be heard. At this time, the backlash should be adjusted, and the gears should be replaced according to the wear.
