What are common diesel engine problems?

Hello Readers, welcome to you this post, in this post, we will know What are comman diesel engine problems? and how to overcome those problems, in this post, we will know in detail, so let know without delay diesel about engine problems

 

What are comman diesel engine problems?

 

What are the problems with diesel engines?

What are comman diesel engine problems?Due to continuous running, many types of shortcomings are seen from time to time in the diesel engine, these problems are of many types, about which we are going to discuss, some of the shortcomings are as follows

 

Diesel supply not coming through the injection pump

This type of problem is also commonly seen for which there may be some of the following reasons
Lack of diesel in the supply tank can also be a reason for this, in which case diesel should be filled in the tank.

Jamming of the diesel filter can also be a reason, in this case, it is necessary to check the filter and remove the deficiency by cleaning it.

One of the reasons for not getting supply in the injection pump can also be that some kind of blockage has come in the diesel supply pipe.

And this type of problem is also seen due to airlocks, in such a situation it becomes necessary to bleed the air.

No full supply of diesel

This is a deficiency that is commonly seen and can be due to some of the following reasons
Due to leakage in the delivery valve in diesel supply, this type of problem is also seen, for this, it is necessary to change the sheet and valve, apart from this, if the valve joint has become loose, it can also be a reason for this type of problem. proper adjustment of

Irregular supply of diesel

This type of problem is also commonly seen in diesel engines in which diesel is not supplied regularly, there may be some of the following reasons for this type of problem
The locking of air is one of the reasons for the irregular supply of diesel. This type of problem is also seen due to the locking of the air system. To overcome this problem it is necessary to bleed the air so that this problem can be overcome. could

 

This type of problem is also seen due to the breakage of the plunger spring. The spring breaks due to excess tension, due to which this type of problem is seen, in this case, it is necessary to replace the spring.

 

A tappet roller is used in this, due to the wear of the roller, this type of problem is also seen, when this happens, the roller should be changed so that this problem can be overcome.

Apart from this, if it is also seen due to the breakdown of the delivery valve, it becomes necessary to replace the valve this type of problem is also seen due to a jam in the filter, in this case, the filter should be cleaned.

Fuel injector pump faults

Low injection pressure

This type of problem is usually seen in the fuel injector pump in the diesel supply system, in which the injection pressure is low, there may be some of the following reasons for this type of problem
One of the reasons for this could be the injector not being adjusted properly. If this type of problem appears, the injector should be adjusted properly. Apart from this, even if the spring is broken, this type of problem is also seen, for this, the spring should be changed.
Apart from this, this type of problem is also seen due to the failure of the needle valve or any kind of blockage in it, for this, the valve should be cleaned and the needle valve should be replaced.

Injection pressure is high

This is also a type of engine problem, sometimes the injection pressure is high, one of the reasons for this may be that the compression screw is too tight, for this, tighten it properly, in addition to this, the nozzle valve is also jammed. maybe a reason

Diesel drips like a drop

One of the reasons for this type of problem may be the nozzle valve being cut or broken or the valve getting jammed, for this the nozzle should be tightened properly or a new nozzle valve should be installed or the nozzle valve should be cleaned.

Joints leak

This type of problem is also commonly seen, for this, the nozzle should be tightened properly and the cap nut should be tightened so that this type of problem can be overcome.

Jamming of the governor lever in a diesel engine is also the cause of this type of problem, it is due to lack of lubrication in it, due to lack of fuel transfer pump, these types of problems are also seen.

 

 

 

Why does black smoke come from diesel engines?

This type of problem is usually seen in diesel engines, the main reason for this is that the fuel does not burn properly, due to wear and tear of the nozzle or any type of leakage in the injector, this type of problem is seen in addition to the airflow supply. This type of problem is also seen due to a lack of balance in

 

 

Why does the engine give white smoke?

This type of problem is also commonly seen, the main reason for this is the fuel pump. If the fuel pump in the fuel system has a fault in the timing of the fuel supply, this type of problem is seen, for this, it is necessary to correct the timing of the fuel pump. Happens so that the fuel supply is on time and this type of problem can be overcome.

Generally, if in addition to the fuel in the combustion chamber, any other oil is leaking from somewhere and mixing with the fuel, then it can also be a reason for white smoke, for this, it is necessary that the right quality lubricant should be used in the engine, which quickly Ifdo not happens 

White smoke comes out of the engine even due to the breakdown of the engine head. The engine head is usually made of materials like cast iron and sometimes problems like cracks are seen. If these types of problems are seen, then the engine head needs to be repaired or replaced

Apart from this, if white smoke comes out due to vapor while starting the vehicle, but this is a common thing, this smoke remains only a little, if it is not reduced, then attention needs to be paid.
