Diesel engine occasional abnormal sound, mainly by listening to the sound to judge. The main engine is now the main reason for the sound of the drum to sort out for the majority of users.
The phenomenon of abnormal spindle spindle:
Baotou North Benz parts engine suddenly accelerated, there is a significant continuous sound, the engine body vibration;
The noise increases with the increase of engine speed and load, and it has nothing to do with the temperature change;
The broken oil test, single cylinder oil without what changes, the adjacent two cylinder and cut off oil, sound significantly weakened;
The engine oil pressure decreased significantly.
The main engine spindle tile abnormal sound mainly in the following aspects:
With the gap of Baotou Benz accessories main bearing and spindle neck bearing due to excessive wear and loose;
Bad lubrication;
Crankshaft axial clearance, crankshaft deformation.
In many cases of engine bearing damage, the tile burning engine failure is purely caused by misoperation. The main are: the brand of oil or not oil filter oil rupture caused by a large number of loss; the long-term overload operation of the engine for ultra high temperature, high temperature oil viscosity reducing and burning tile. In short, as long as the correct use, operation and maintenance, engine burning tile failure is very rare.
If there is a main axis of the phenomenon, the following methods can be used to judge:
The engine speed to run, hand shake the throttle, throttle repeated test, heavy sound, muffled, and with the engine speed increases; in the jitter accelerator, the sound clear, engine vibration phenomenon, this is the crankshaft main bearing ring.
The engine in speed or idling sound obvious, the body has a larger vibration at high speed, oil pressure decreased significantly, which is open, shedding, spindle Wasong alloy melt.
The open plus oil cover, hear the sound of clear, single cylinder oil had no change, but the two adjacent cylinder oil break, noise decreased or disappeared.
4 use the needle to listen to listen to, on both sides of the cylinder body sound obvious.
5 on the Baotou North Benz parts of the clutch pedal, noise reduced or disappeared, this is because the crankshaft axial clearance is too large and noisy. Curved auxiliary main bearing abnormal sound, must be timely maintenance, can not continue to run, otherwise it will lead to greater failure, causing a greater loss.
