During the operation of the diesel or gasoline power unit, the motorist may face the situation when the motor is not gaining momentum when pressed. It is worth noting that after the installation of HBO on the car, such a problem is rarely appearing when the engine does not gain momentum on gas, although it goes normally on gasoline. Malfunctions of various kinds can be wounded in simple things, and may indicate the need for serious engine repair. About this further in the article.

Why the engine does not gain momentum

If the engine has stopped gaining momentum, first of all, you need to analyze how and when it manifested. That is, the engine refused to unwind unexpectedly or the problem with the development of revolutions progressed gradually. It is also necessary to pay attention to the absence of either the presence of other symptoms.

The bottom line is that if a serviceable engine refuses to gain momentum after performing any repair or other operations, it may be the result of errors during the assembly, not connected sensor and so on. In such cases, the breakdown is determined more accurate and faster with the help of an independent inspection or immediate return of the car to the service where the vehicle was repaired before.

If the engine without visible reasons does not gain momentum, troit, the car systematically stalls and so on, then the motor requires in-depth diagnostics. The reasons for such a malfunction can be conditionally divided into complex and simple, appearing immediately or received prerequisites.

Why the engine slowly gains momentum

The rumble at the rumble is strongly affected by the composition, feed efficiency, the fullness of combustion and the timeliness of ignition of the air-fuel mixture. A frequent reason for the DVS is not gaining momentum (diesel, carburetor, injector, car per gas), are malfunctions in fuel and air supply systems, as well as in the ignition system.

Why engine is gaining momentum and stall

It does not rarely, it happens that the engine is gaining momentum and stalls as a result of a scored mesh-filter fuel pump. The fact is that on this filter, deposits from the gas tank accumulate on this filter. Due to the pressure in the system, there is not enough fuel, the pump performance decreases, and the engine itself cannot function normally in various modes. To resolve the problem, you need to clean or replace the grid. However, this is only one possible reason for many others that we will look at.

Simple causes due to which the engine does not gain momentum, how to eliminate them

Experts allocate such:

• Highly polluted air filter reduces air ability to penetrate through the filtering element, because of which the operation of the motor becomes uneven, the engine loses power and ceases to gain momentum. Another frequent reason, due to which there may be problems with air supply, is an extraneous object, accidentally turned out in the air filter housing (plastic bag, rags and so on).
  
• It is also necessary to pay attention to sucking unnecessary air when inlet due to different intake system defects. Such a problem may appear unexpectedly or gradually progress. It is worth noting that the engine, as a rule, ceases to gain momentum as a result of a strong air supply. In such a situation in the composition of the air-fuel mixture, the optimal ratio of fuel and air is significantly deviated from the norm. The working mixture is very "poor" (minimum fuel and a lot of air). At such charge, the motor will start, but does not gain momentum when driving, and also functions with interruptions.
  
• The same picture is observed when the required amount of fuel is not supplied in the engine. The culprit of this can be a strongly scored fuel filter. It is worth saying that with the launch of the DVS problems may not be observed, because the fuel is enough to work on the XX. At the same time, during the driving, the TC can twitch, with a large delay to respond to pressing the gas pedal with a large delay, during the set of revolutions, the failures appear or the engine does not extend more than a certain mark on the tachometer.
  
• If high-voltage wires or spark plugs do not function properly, then the ignition of the mixture can be disturbed. As a result, the fuel charge in the cylinder may begin to be inadequate, the turns do not grow, the power of the motor drops. Such consequences entails pollution or grinding of candles (especially on motors with essential mileage), incorrectly displayed clearances on the electrodes, damage to the candle housing.
  
• On the occurrence and quality of sparks can also affect the breakdown or cliffs of spark plugs (high-voltage). In such cases, the motor begins to told, a set of revolutions deteriorates, ignition and ignition skips are observed.

Most of the above reasons of the car owner can determine and eliminate on their own. You need to check the wires of the ignition system and the candles on the spark, in the fuel ramp measure the pressure (on the injection engines), to inspect the air filter for the presence of contaminants, replace the fuel filter and so on.

Complex, sudden causes of which the engine is not gaining momentum how to eliminate them

Now consider malfunctions that may require some skills, knowledge, equipment for diagnostics or be a reason for traveling to car service. In this fault list, as a rule, there are such when the motor does not gain momentum due to the failure of one of the ECM elements, the power system, ignition, and so on. That is, here it is not about "consumables" (nozzles, filters, wires, candles), but about the details. At the same time, take into account both that fault has progressed gradually or breakdown occurred unexpectedly.

• One of the reasons is the bounded phases of the timing. The violation of the synchronous operation of the gas distribution mechanism relative to the output clocks and the inlet entails the untimely opening of intake and exhaust valves. The malfunction appears due to errors when replacing the timing belt, if the belt rearranged on one or more teeth. Another reason can be incorrectly adjusted valve (the problem does not appear sharply), the problem of the timing chain drive, different damage in the system of changing the phase distribution and so on.
  
• An unexpected breakdowns must be attributed to the outlet of the ignition module, as well as problems of ignition coils. In this situation, ignition skips begin, the motor troit and can no longer gain momentum.
  
• Also check the power of injection injectors. When problems with the wiring occurs, the control signal on the nozzle comes with interruptions or is not applied at all. As a result, the nozzle does not open in a timely manner, in one or several cylinders there are omissions of ignition, the motor loses power and does not gain the required number of revolutions.
  
• May fail the fuel pump or the TNLD on the diesel. As a rule, this fault does not appear immediately (except for the damage to the electrical wiring per pump). Much more often the pump performance decreases gradually. But sooner or later, the fuel pump will begin very weakly swing fuel, the pressure will be enough only to work on the XX. The increase in revolutions and the load will lead to the fact that the motor is not spinning, it stalls under load and so on.
  
• Sometimes similar symptoms entail severe injector pollution. Riding on low-quality fuel, as well as ignoring the desired procedure for cleaning the nozzles every 40 thousand km. The run may indicate that the performance of one or several injectors fell significantly.

  

• The state of the EGR system can also be affected on the motor turnover, as well as the bandwidth of the particulate filter or catalyst. As a result of a scored catalyst, the removal of exhaust gases deteriorates, the engine literally "chips" and does not gain normal rev.
  
• In parallel, you need to check different ECM sensors (DMRV, DPDZ and others). Their incorrect functioning can affect the composition of the mixture (the amount of air and fuel supplied and fuel).

Late engine maintenance, which brings irresponsible attitude to the car

Finally, I would like to say that the timely replacement of wires and spark plugs, filtering elements and fuel pump filters, injector cleaning, throttle, correct throttle adjustment and other service procedures will give you the opportunity to get the maximum power of your engine. Ungrevoyed service of the engine, on the contrary, can lead to destabilizing the operation of the motor and other more serious problems up to overhaul.

As for the car with HBO, then from the correctness of the setting and installation, timely replacement of filters, as well as maintenance of other HBO elements will depend on both the power of the motor and its turnover and the total service life of the engine.
