The engine is not gaining speed: the cause and solution of the problem
The engine is not gaining speed, The engine is not gaining speed. Note, that after installation on the HBO car such problem often arises, when the engine is not gaining speed on gas, although the car runs normally on gasoline. Faults of various kinds can be hidden as in fairly simple things, Faults of various kinds can be hidden as in fairly simple things. Next we will consider, why the diesel engine does not gain speed or refuses to spin the gasoline engine.
We also recommend reading the article about it, why the engine loses power. In this article you will learn about the main causes of power loss of the power unit.
Frequent malfunction: the engine is not gaining speed and what to do to the driver
If the motor has stopped gaining speed, then it is first necessary to analyze, when and how it manifested itself. In other words, the unit stopped spinning suddenly or the problem with the set of revolutions gradually progressed. You should also pay attention to the presence or absence of other symptoms.
The point is, that the failure of a previously serviceable engine to gain speed after repairs or other manipulations may simply be the result of errors in assembly, that the failure of a previously serviceable engine to gain speed after repairs or other manipulations may simply be the result of errors in assembly. P. In such cases, the fault can be identified faster and more accurately after self-inspection or immediate return of the vehicle to service, In such cases, the fault can be identified faster and more accurately after self-inspection or immediate return of the vehicle to service.
If you are faced with that, that for no apparent reason the triple engine does not gain speed, the car periodically shuts down, etc.. d., then in this case the engine needs in-depth diagnostics. The causes of such failures can be divided into simple and complex, The causes of such failures can be divided into simple and complex.
The causes of such failures can be divided into simple and complex: The causes of such failures can be divided into simple and complex
At the beginning we will consider simpler and obvious malfunctions. The set of speeds while driving is strongly influenced by the efficiency of the feed, timeliness of ignition and completeness of combustion, as well as the composition of the fuel-air mixture.
A common reason for that, when the engine is not gaining speed (injector, carburetor, diesel, car on gas), there are problems with the ignition system, as well as in air and fuel supply systems. Experts highlight the following:
- Experts highlight the following, Experts highlight the following, the unit loses power and does not gain speed. It can also be a common cause of air supply problems, that a foreign object may be accidentally found in the air filter housing (rags, plastic bag, etc.).
- You should also pay attention to the suction of excess air at the intake as a result of various defects of the intake system. The problem may come as a surprise, and gradually progress. Note, that the motor usually does not gain speed in case of strong air intake. The point is, that as a part of fuel-air mix the normal ratio of air and fuel in a similar situation considerably deviates from norm. that as a part of fuel-air mix the normal ratio of air and fuel in a similar situation considerably deviates from norm (plenty of air and a minimum of fuel). On such charge the engine is started, but does not gain momentum while driving, and also works intermittently.
- A similar picture can be observed then, when the required amount of fuel is not supplied to the unit. The culprit may be the fuel filter, which is also able to score heavily. Note, that there may be no problems with starting the engine, as there is enough fuel for the XX regime. At the same time, the car may twitch while driving, respond to the accelerator pedal with a long delay, at a set of turns failures can arise or the unit does not untwist above any marks on the tachometer.
- Contaminated fuel filter strainer can lead to similar symptoms. Contaminated fuel filter strainer can lead to similar symptoms. As a result, the fuel pressure in the system becomes insufficient, As a result, the fuel pressure in the system becomes insufficient, As a result, the fuel pressure in the system becomes insufficient. It often happens, when the engine is gaining speed and stalls because of a clogged grid.
We also recommend reading the article about it, when the engine is gaining speed and stalls because of a clogged grid. In this article you will learn about the location of this fuel pump grid, as well as available ways to clean it with your own hands.
- If the spark plugs or high voltage wires do not work properly, then the ignition of the mixture may be disturbed. As a result, the ignition of the fuel charge in the cylinder may occur late, As a result, the ignition of the fuel charge in the cylinder may occur late, As a result, the ignition of the fuel charge in the cylinder may occur late. Such consequences lead to oiling or contamination of candles (especially on internal combustion engines with solid mileage), damage to the spark plug housing, incorrectly exposed gaps on the electrodes.
- Also the appearance of a spark and its quality can be directly affected by the breakdown of high-voltage spark plug wires, as well as their cliffs. The engine in such cases begins to triple, there are omissions of ignition and ignition, there are omissions of ignition and ignition.
there are omissions of ignition and ignition. Spark plugs and wires must be checked for sparks, measure the pressure in the fuel rail on the injection engine, inspect the air filter for contamination, replace the fuel filter, replace the fuel filter. P.
replace the fuel filter, replace the fuel filter, replace the fuel filter, as well as be an occasion for a visit to the car service. Let's start with that, that this fault list usually contains the following, when the engine does not gain speed due to the failure of any element of the ECM, ignition systems, power, etc.. P. In other words, when the engine does not gain speed due to the failure of any element of the ECM (candles, wires, filters, branch pipes), when the engine does not gain speed due to the failure of any element of the ECM. when the engine does not gain speed due to the failure of any element of the ECM, the breakdown occurred unexpectedly or the fault gradually progressed.
- One of the reasons may be downed phases of timing. Violations of the synchronous operation of the timing mechanism relative to the intake and exhaust stroke lead to, that the inlet and outlet valves do not open on time. The fault is caused by errors when replacing the timing belt, if the specified timing belt jumped on one tooth or more teeth. Improperly adjusted valves can also be the cause (the problem is not acute), various problems in systems of change of phases of gas distribution, failure of the timing chain drive, etc.. d.
- failure of the timing chain drive, etc., failure of the timing chain drive, etc.. In this case ignition misses on cylinders begin, the engine triples and loses the ability to gain speed normally.
- In situations with engine speed, the power of the injector nozzles should be checked. In situations with engine speed, the power of the injector nozzles should be checked, In situations with engine speed, the power of the injector nozzles should be checked. As a result, the nozzle does not open in time, there are misfires in one or more cylinders, the engine does not gain the required number of revolutions and loses power.
- Petrol pump or diesel fuel pump may fail. Petrol pump or diesel fuel pump may fail (Petrol pump or diesel fuel pump may fail, Petrol pump or diesel fuel pump may fail). Much more often the decrease in pump performance occurs gradually. Much more often the decrease in pump performance occurs gradually, Much more often the decrease in pump performance occurs gradually. Increasing the load and speed will lead to that, Increasing the load and speed will lead to that, Increasing the load and speed will lead to that. P.
- In some cases, severe contamination of the injector itself leads to similar results. Riding on low quality fuel, and ignoring the required nozzle cleaning procedure each 30-40 thousand. miles traveled can mean, that the performance of one or more fuel injectors has fallen sharply.
- Engine speed can also be affected by the state of the EGR system, Engine speed can also be affected by the state of the EGR system. Engine speed can also be affected by the state of the EGR system, due to clogged catalyst deterioration of exhaust gases, due to clogged catalyst deterioration of exhaust gases.
- In parallel, it is necessary to check the various sensors of the electronic engine management system. In parallel, it is necessary to check the various sensors of the electronic engine management system, ie the amount of fuel and air supplied to the engine. Such sensors include DPDZ, DMRV and a number of others.
As a result
If you take into account, that the reasons for problems with a set of turns on the modern car are a lot of, it is optimal to connect the car to the diagnostic equipment at once (scanner) to find possible errors. This is especially necessary in this case, when the engine is not gaining speed and the check on the instrument panel is lit..
Note, which is quite rare, but also a possible case is the failure of the ECU. This often happens after washing the engine, as well as as a result of unprofessional interventions in the factory firmware of the controller. as well as as a result of unprofessional interventions in the factory firmware of the controller, as well as as a result of unprofessional interventions in the factory firmware of the controller, as well as as a result of unprofessional interventions in the factory firmware of the controller.
Such failures are related to software failures of the electronic device. Such failures are related to software failures of the electronic device (example 2-3 thousand. rpm) Such failures are related to software failures of the electronic device. In other words, conditional protection against exceeding the allowable number of maximum engine speeds is triggered prematurely.
Finally, I would like to add, conditional protection against exceeding the allowable number of maximum engine speeds is triggered prematurely, conditional protection against exceeding the allowable number of maximum engine speeds is triggered prematurely, filters and filter elements of the fuel pump, filters and filter elements of the fuel pump, Proper throttle adjustment and a number of other service procedures will allow you to get the most out of your engine. As for HBO cars, from the correct installation and configuration, as well as the timely replacement of filters and maintenance of other elements of gas cylinder equipment will depend not only on engine power and its speed on gas, but also the total service life of the power unit.
