Is it possible to prevent diesel engine malfunctions and ensure the quality functioning of all vehicle systems? The use of high quality fuel mixtures, compliance with operational requirements, and regular diagnostics are the key to the trouble-free operation of a diesel engine.
How to make scheduled and emergency repairs of diesel engines
Repair of diesel engines of passenger cars, their fuel equipment, high pressure fuel pumps (TNFP) are expensive, complex operations. This type of repair work is most often trusted by professionals.
Increasingly, car owners are purchasing diesel vehicles due to their economy, reliability, long service life, reduced emissions, and improved performance.
In modern cars, as a result of diagnostics, there are often cases of diesel engine malfunction not through the fault of the injection pump itself, but as a result of failures in the settings of electronic control systems. Here it is enough to ensure the correct setting of the electronics, and the engine will begin to work safely.
Classification of defects in diesel engines
When buying a diesel car, you need to remember the need for scheduled repairs. Engine malfunctions are divided into the following groups:
- Defects received during the manufacture of the car.
- Features of the diesel engine device
- Violations committed during the operation of the car.
- Low qualification of workers in the provision of services.
- Failure of some engine elements due to the general aging of the machine.
Algorithm for diagnosing fuel systems of diesel engines
When checking the operation of diesel engines, work is carried out in the following sequence:
- Control of diesel fuel supply by the pump, its quantity, pressure.
- Fuel pump performance analysis - shaft rotation speed during diesel start-up and completion.
- Checking the frequency of fuel injection in the injection pump section.
- Monitoring the condition of the injectors.
As the measures to check fuel equipment systems are completed, an objective description of the condition is given, a list of restoration operations is revealed - repair, replacement of nozzles, high pressure fuel pump, fuel tanks. The conclusions of the diagnostics also include the determination of the total cost of repair work, taking into account the cost of original components and parts that require complete replacement.
Description of restoration work
Repair of diesel cars is carried out by qualified experienced craftsmen. The list of mandatory activities includes the following operations:
- Restoring the functions of high pressure fuel pumps.
- Turbine restoration.
- Adjustment of injector settings.
- Replacing the cleaning filter.
- Flushing operations using special solutions.
Due to the design features and complexity of diesel engines, the use of specialized stands, diagnostic and repair equipment is required. Only with high-quality maintenance will a long and trouble-free service of a diesel car be ensured.
Description of the causes and symptoms of diesel engine malfunctions
The need for frequent repairs of diesel engines and their elements is required if the owner of the car does not comply with the prescribed operating standards:
- operation of a car at ultra-high speeds;
- operation of a diesel engine using low-quality fuel with a high content of harmful mechanical impurities and water droplets;
- the use of conventional brands of diesel fuel in the cold period instead of winter fuel, the peculiarity of diesel fuel is that it loses its fluidity at temperatures below minus 5˚С;
- pouring ordinary water into the car's cooling system;
- ignoring the requirements for replacing engine oil after the next run, equal to 7500 kilometers;
- operation of the car without mandatory scheduled flushing of the engine nozzles using special fluids to clean the injector.
Diesel engines don't like high revs. Prolonged travel at high speeds can cause breakdowns leading to a major overhaul of the diesel engine, because it overheats at high speeds, and its elements receive destructive deformations. The cause of the engine overheating may be factors such as high ambient temperature, worn rings, valve wear, lack of a preliminary three-minute warm-up.
Determining the need for repair of a diesel engine and its components is carried out according to the following criteria:
- the occurrence of difficulties when starting the engine in the cold period;
- a sharp decrease in power characteristics;
- the presence of tapping during the movement of the car;
- stop the engine when the speed increases.
If one or more signs are detected in the operation of the machine, it is necessary to contact the repair service in order to carry out diagnostics with subsequent repair of the diesel engine to eliminate the noticed defects.
When is repair and adjustment of the injection pump necessary?
The high pressure fuel pump requires repair and adjustment operations with the following symptoms:
- a sharp increase in fuel consumption;
- violation of the supply of the fuel mixture to the nozzle;
- the timing belt comes off the gear;
- the appearance of fluid leaks from the high pressure fuel pump;
- the occurrence of noise in the pump of unknown origin;
- increase in the amount of smoke emissions.
The fuel mixture is injected through the nozzle into the combustion chamber. Black smoke indicates that there is insufficient pressure in the injector. White smoke means high blood pressure.
To prevent the toothed belt from coming off the gear, it must be replaced after the next mileage of the machine equal to 60,000 km. If an oily liquid gets on it, the source of the leak must be urgently eliminated.
Having unscrewed the fuel system nut, it is necessary to remove the sediment elements from the filter.
Overhaul provides for the adjustment of all necessary operating parameters of the internal combustion engine. Car owners should overhaul a diesel engine at the first sign of a breakdown in it.
Diesel engine overhaul
Overhaul of diesel engines is carried out in several stages. Employees of service stations and car owners who decide to repair a diesel engine with their own hands adhere to the following sequence of operations:
- removal of the unit;
- engine disassembly;
- washing and cleaning parts and assemblies;
- analysis of the state of the elements to determine the degree of wear, the formation of cracking;
- determination of parts and assemblies to be replaced with new original samples;
- a thorough check of the crankshaft for the formation of cracks and the size of the gaps;
- crankshaft restoration;
- restoration of the cylinder block;
- cylinder head repair;
- diesel engine assembly;
- carrying out cold running-in at a specialized stand;
- adjusting the amount of toxic gas emissions and checking the engine idle speed.
When performing assembly operations, special torque wrenches are used to ensure high-quality tightening of all installed components and parts.
Cold running involves forced rotation of the crankshaft. Internal combustion engines require mandatory filling of coolant and engine oil of the appropriate viscosity.
It is strictly forbidden to give an increased load on the diesel engine in the form of towing vehicles and trailers, to use high speeds until a mileage of 150 to 300 kilometers is reached after the repair.
Self repair diesel engine
In order to repair a diesel engine with your own hands, you need to acquire the necessary tools and fixtures:
- torque wrench;
- set of wrenches;
- technical manual for the operation and repair of a car of this brand.
Oil and all liquid components of the engine are preliminarily drained. The fuel system is disconnected from other vehicle components. Disassembly is carried out with maximum concentration, given the hidden location of some fasteners. The removal of the head, pan, connecting rod is made above the inspection hole. Only after these events, access to the defects of the engine appears.
With regular independent overhaul of a diesel engine, the operation of the machine will not cause big problems, since the operations carried out contribute to improving the quality of the car’s functioning:
- Increased engine uptime.
- Guaranteed to reduce the risk of breakdown of the internal combustion engine.
- Reliability of fuel system adjustments.
Car owners who carry out engine overhauls on their own know and comply with the basic requirements that ensure safety during their operation:
- the use of engine oil having the appropriate viscosity of this model;
- regular checks of the condition of air, fuel, oil filters and mandatory replacement with new samples when they fail;
- compliance with the speed limit in accordance with the permissible loads on diesel engines;
- competent regulation of all systems of the internal combustion engine.
To repair your diesel car yourself, you need to have experience and be aware of the design features of diesel engines.
Car owners are obliged to treat diesel vehicles with frugality, compliance with operating rules, without ignoring planned analytical and repair measures.
We repair not only cars, but also trucks and special equipment. For repair and diagnostics, only high-precision equipment, specialized stands, and original consumables and spare parts are used. The whole process of work is carried out by certified specialists with extensive experience in the repair and diagnostics of complex diesel (fuel) equipment.
During the operation of a car, most motorists are faced with such a concept as engine repair, in particular, diesel engine repair. Work on the repair and restoration of the original performance of a diesel engine is a rather complicated process that only professional craftsmen can do. Unskilled intervention in the complex fuel equipment of diesel engines, improper adjustment and low-quality spare parts used in the repair lead to serious consequences, in which it is quite problematic to repair the engine.
Authorized service center for fuel equipment Bosch- the company LLC "Autodiesel" in a wide range of services offers professional repair of diesel engines with preliminary diagnostics of faults.
When is an engine overhaul required?
Malfunctions in the operation of a diesel engine can occur for a number of reasons, where the main ones are:
- Low-quality fuel (it is one of the first in the list of root causes of diesel repair);
- Critical wear and wear of parts by more than 70 - 80%;
- Mechanical damage to the main structural parts of the diesel engine.
And these are only the causes, while the consequence is the occurrence of a number of malfunctions, expressed as follows:
- Difficult start of the engine and extraneous noises / knocks in the operation of the diesel unit;
- Instability of revolutions and uneven idling;
- Reduced power and throttle response of the engine;
- Increased fuel and oil consumption under the same operating conditions;
- Increased smoke and discoloration of the exhaust (gray / black).
And even if you, as a novice car enthusiast, cannot visually determine an engine malfunction, the inclusion of warning lights on the dashboard signaling problems in the operation of the engine is a serious reason to turn to the help of certified specialists of the AvtoDiesel technical center. Our masters will carry out step-by-step diagnostics and highly qualified repair of your car engine with a quality guarantee, which, as a result, will increase the performance and efficiency of the engine, and extend its working life.
Classification of diesel repair - in-line, unscheduled, overhaul
Repair of diesel engines, which is carried out by our masters, can be classified into three main categories.
- In-line (technical) repair of a diesel engine with the replacement of consumables and worn parts, the resource of which is lower than that of the power unit.
- Unscheduled engine repair - its need arises in the event of a sudden failure of structural parts and assemblies, which may be due to mechanical damage to the diesel engine, the installation of low-quality spare parts during repair / maintenance, and for a number of other reasons.
- Capital (scheduled) repair of the engine, which is carried out either by the mileage of the car, or due to the development of the main working resource of the diesel engine by more than 80%.
Specialists of AvtoDiesel LLC determine the need for an engine overhaul based on the results of diagnostics, which is carried out using modern software and diagnostic scanners.
Major overhaul - what does it involve?
What, besides visual inspection and diagnostics, does an engine overhaul in the AvtoDiesel technical center involve? This is not just an engine overhaul with the replacement of worn parts, it is a full range of work, during which all individual components and the engine itself as a whole are brought to a state close to the original (factory) one.
The concept of overhaul is quite broad and involves:
- Dismantling, disassembly and troubleshooting;
- All motor components are checked for defects, plus a search is made for “weak”, critically worn parts, their replacement or boring;
- The piston group is changing, the cylinders are being bored, all liners, rings, valve stem seals, etc. are subject to replacement;
- The geometry of all rubbing parts is measured, the dimensions are compared with factory indicators, and deviations from the norm are determined;
- The fuel equipment is checked.
The main criterion for maintaining the stability, performance and performance of a diesel engine is the timely completion of all routine maintenance work on the vehicle. This list can include the use of only high-quality spare parts and fuels and lubricants when replacing parts, plus carrying out scheduled / unscheduled work only in a good service center.
Our car service "AutoDiesel" offers its services for the maintenance and overhaul of engines of passenger cars / diesel trucks and special equipment at competitive prices, using original components / consumables, and with a guarantee of the high quality of all work performed.

Andrew: The timing belt broke. Met valve
Diesel engines are very popular not only among car owners. These power plants are often used as a drive in generators, pumping units and other units. The demand for diesel engines is due to their durability, power, efficiency, reliability and unpretentiousness.
At the same time, these are complex mechanisms that require proper care and timely maintenance. Repairing a diesel engine that has not undergone the required maintenance on time can cost a decent amount. Of course, some types of breakdowns can be caused by natural aging. But in most cases, it is the correct and timely service that can significantly extend the life of the drive.
What you need to know when servicing
As a rule, for any engine, the manufacturer provides for a schedule and maintenance schedule. Most often they are prescribed in the instructions for the unit itself, where diesel is used as a drive. Of course, to increase the durability and quality of work, you should strictly adhere to such recommendations. The most important of them relate to such elements as:
Oil change - in cars, the schedule is calculated by mileage, and in devices - by hours. Most often, the time for the necessary replacement is indicated by the manufacturer, but when using the engine for the first time, it is recommended to change the oil to a new one after 20 hours of operation. If the unit is not equipped with an hour meter, a logbook must be kept. Neglecting this type of maintenance is one of the most common causes of engine failure.
Air filter - lubricating, cleaning or replacing the filter element ensures that the engine is protected from dust and dirt. If the filter can no longer be cleaned, it should definitely be replaced. Accordingly, it is recommended to check the status of this element regularly.
Fuel - there is no need to talk about the need to refuel only with high-quality fuel. Even regular filter replacement cannot protect the engine from damage when low quality fuel is used. It is also necessary to store fuel in an airtight container to prevent dirt from entering.
Storage - If the device is not going to be used with a diesel engine in the near future, the fuel tank must be emptied. It is also recommended to run the engine for at least 20 minutes once every few months. This will lubricate all its elements and prevent the formation of corrosion.
What is the difference between maintenance and repair
In a simple understanding of the meaning of these words, it is understood that normal or service maintenance consists of a set of measures to maintain engine performance. Such work may consist of cleaning or replacing some components. In turn, repair is a process in which a faulty engine is brought to a state close to that in which it left the factory. As a rule, repairs require the following work: disassembly, cleaning, detection of defects, replacement or repair of faulty components.
Very often, such elements as the crankshaft, cylinders, cooling systems, fuel supply and oil lubrication, crank mechanism are repaired. After-sales service provides only a bulkhead of the engine with the replacement of worn-out elements.
Benefits of cooperation with the company
It must be remembered that poor maintenance is another reason for the failure of a diesel engine. But if most owners can change the oil or filter on their own, then only experienced professionals can diagnose and replace worn components. And when an engine overhaul is required due to low compression and power loss, it makes sense to contact specialized companies directly.
Firstly, this will allow you not to be left alone with the problem, since the owner will know who to contact in case of difficulties in work.
Secondly, such companies do not keep amateurs in workshops, which excludes poor-quality work.
Thirdly, such maintenance or repair is cheaper, since the engine will last much longer, and you will not have to spend money on the purchase of parts or entire assemblies.
Fourthly, due to the presence of competition, all companies provide the most favorable prices for their work.
Therefore, it makes no sense to try to save on maintenance, since the higher cost of quality repairs means a longer diesel engine life.
About 20% of customers come to us after cheap diesel engine repairs carried out by private specialists, as a result of which they lose a lot of time and money. Therefore, we strongly recommend that you contact only professionals with the appropriate equipment!
