Various malfunctions associated with the operation of the engine, transmission and mounted units can manifest as idlingand under the load in motion, as well as in transition modes. The breakdowns can often be determined by the presence of obvious leaks. technical fluids, obvious knocks, unstable work, failures, etc. Next, we will look at the possible reasons why, during the movement, the machine with an injector begins to twitch, that is, noticeable jerks appear.

Fuel system problems
If the machine twitches when driving, then the diagnostics should be diagnosed with. The main symptoms of the engine power system faults are car jerks in motion. These signs of breakage are manifested in several situations.
- There is a need to sharply accelerate. At this point, the driver strongly presses the gas pedal, but the desired pickup does not occur. Instead, the car twitches, after which it begins to accelerate with further jerks or without them. An option is also possible when the jerks begin after the gas reset.
- The problem is noted in the case when the car suddenly pulls during the movement at cruising speed. In other words, failures and jerks in dVS work It can be noticeable both at the time of changing the speed of rotation (during overclocking and resetting gas) and with constant engine speeds (the gas pedal is in one position).
First of all, it is necessary to eliminate the likelihood of refueling fuel, importing the fuel-fueling system and the flows of fuel highways. The next element that requires control is the fuel filter.
In the event of a reduction in its capacity, the engine will not enough, especially with a sharp rise of revolutions and the growth of the load on force aggregate. It is also necessary to make sure that air filter It does not have significant pollution.
Excluding the above reasons must be proximized to check the injector. For accurate results, the fuel pressure is measured in the fuel rail (ramp), and the operation of the nozzles is checked.
Low pressure in the fuel rail leads to the fact that at the moment of sharp pressure on the gas there is a wide discovery throttle valve, the damper position sensor sends the signal to. The electronic unit Control under reduced pressure is not able to quickly provide the supply in due volume, as a result of which the car begins to pull on the go.
The engine can also work unstable and twitch on the go in the event that there are problems in. In addition to the jerks, there is a power loss, increased flow etc.
An independent check involves the diagnosis of power wires, spark plugs, ignition coils, DPRV. To detect a possible reason, it is necessary to turn off the ignition, after which the reliability of the attachment of high-voltage wires on the coil and candlelight is checked. Next, the motor is launched and its work is estimated for hearing. Special attention should be paid to peculiar "cracklers", which may arise as a result of the fact that the spark breaks into some kind of site.
Then the ignition candles are filled to examine their status. The destruction of the insulator and other defects on the candle hull, as well as the erosion of the electrodes are not allowed. You should also pay attention to the Nagar, which may be present at the candlelight.
Such a nagar is removed mechanically with the help of a rigid brush. If the machine does not stop twitch after cleaning or replacing the candles, then it will not be superfluous to check the camshaft position sensor by a multimeter.
Other reasons
Among the others possible causeswhich can cause jerking machines when driving, you need to highlight possible problems with clutch on mechanics and malfunctions automatic boxes Transmissions.
Concerning mechanical transmissions, jerks can occur after the transition to a certain transmission at the moment when the driver begins to let the clutch pedal. In this case, it is worth starting with checking the status of a basket, a clutch disk, released Bearing etc.
If the machine with the "automatic" moves with jerks or twitching during acceleration, then it is necessary to diagnose the gearbox, check the level transmission Oil and operability of control electronics.
Finally, we add that noticeable jerks when braking with some drivers are mistaken for failures in the work of the engine. Actually frequent cause This behavior of the car can be worn brake discs.

With a sharp press on the gas pedal, the engine twitches, jerks and failures appeared, the car does not gain speed: the main causes of malfunction and diagnosis.
Each of our interlocutors has already managed to roll on their "passing" without a small 100,000 kilometers. Agree, quite impressive mileage. And how old are these cars? To tell about each separately - where-when they bought, in what configuration, as exploited - we will not. We only note that the age age of cars is from 3 to 5 years, but devote all the attention to the discernment of what happened to them.
The sores, of course, have enough for each car (and not only in Chinese). Only the degree of their criticality and the frequency of manifestation differ. It is clear that Hover H5 is from the point of view of breakdowns and problems that are detected during operation. However, so terrible, as far as the products of the CNR auto industry are representing, you will not call it.
Judge for yourself: after 50,000-70,000 km, the most common problems faced by the "hover rover" turned out to be "glitches" of all sorts of controllers. For example, replacement requires a sensor dispensing box - Although if you do not use Rocky, then you can not bother. Upper the car at the time of launching the motor almost in all cases indicated that it would be nice to change the camshaft sensor. And even quite frequent complaints cause malfunctions in the engine at raw weather, which are treated with flashing control unit.
Of the absurd defects - the short-circled gear levers, the curvature of glasses in the front doors when trying to raise them up, closure in the heating electrical system of seat heating. Everything would be nothing but ride on a hot chair - the pleasure is not pleasant.
After a run of 70,000-100,000 km, especially if the "Chinese" periodically drilled off-road, often the air-conditioning system nozzles are often scattered. As it is easy to guess, the mud and moisture falling on them. Plus a short air conditioner tube in the fastener's place comes with a body metal, which makes corrosion and as a result - a break. Still fastened to burn windows. Here, in fact, all.
During the time the Hover H5 is sold in Russia, its owners have concrete vehicles of the car: everything is as one consider it necessary to equip it with crankcase and protection. Some strains the need to open a gas tank hatch key, as well as the ever dirty opening button of the fifth door. Someone complains about the too harvester bumpers, with which it is easy to say goodbye to the unsuccessful maneuvering in the parking lot. As for the interior, in the opinion of the fans of the model, it would be worthwhile to bring the crickets settled here and eliminate the unpleasant creak, manifesting themselves on off-road.
How did you think about it?
I did not come up with technology. I am just the owner of the author's license. And I bring the technology to mind.
How long have you been doing this?
Tenth year Professionally improving car characteristics using mechanical refinement. I do not deceive anyone and I do not run away from anyone. To deceive people is not my specialization, and deceive, yourself more expensive. I give a guarantee for your work. The described changes in cars are recorded by customers.
What auto make a choke refinement is done?
The refinement of the throttle is made on gasoline (injection, carburetor) engines. On the diesel engines We use other technologies.
How much will the engine power increase after refinement of the throttle?
Maximum power engine gives high revolutions 4000-7000 rpm depending on the engine. It is this indicator that you have registered in the documents. On small and medium turnover, the engine does not produce maximum power. With the help of this technology, I increase the power on small speed and partially on medium turnover. And this indicator does not affect the maximum engine power. Therefore, the horses remain, and the thrust on small revolutions increases.
How can choke reflect on the engine resource?
Positively! The smaller the fuel is burned, the smaller the patches and the piston rings are formed. The absence of nagar does not pull other constructive problems with the engine. As well as the resource of the car catalyst is extended if it is still. Because not burned gasoline does not guess in the catalyst. After improving the choke, you start ride with smaller speed. Less revolutions reduces the wear of the driving parts of the engine. Thus, the engine is engaged in the engine.
Why manufacturers do not immediately make choke refinement?
And why does the manufacturers immediately do what the market is to improve the car?!
First, the technology is young. Secondly, the manufacturer puts in a car what the market offers. The lion's market share is occupied by Bosch. Therefore, this refinement should do Bosch. Thirdly, there is information that this technology bought Toyota and BMW. It is possible that this refinement will already be on new models of these manufacturers.
Malfunctions and disorders in the operation of the engine can be manifested in different ways, starting with suspicious sounds that are coming from under the hood, with leaks that remain on the asphalt after a long parking, ending with the jerks while driving.
Rods during the movement of the car may occur no matter how you press the gas pedal, this happens as a result of a short-term change of rotation speed crankshaft. The failures may occur not only during overclocking, but also when the gas is discharged, as well as with the constant movement and the same position of the gas pedal. In order to understand why car jested when driving It is best to contact the specialists for a hundred, since, most likely, the injection systems will also have to produce, and for this, as you understand, you need to have special equipment. In most cases, the jerks occur during the ride due to disruption of the pressure in the fuel ramp, or as a result of a malfunction of the throttle position sensor (DPDZ).
The car twitches while driving - reasons
Sometimes during the start of movement, when you touch, there is a "failure", while the newcomers often even can even stall the motor. This effect occurs exactly at the moment when the throttle is opened when the engine switches with idle speed into the load mode. IN modern engines The engine helps the driver, for the smoothness of the ECU, receiving a signal from the DPDZ about the position of the throttle will increase the fuel supply. However, if the pressure in the fuel ramp is weak, the fuel will still not be enough.
Cause of jerks while driving It can also be conclusted in the electromechanical part of the throttle or. The reason for such pollution is also often caused by a lack of pressure in the fuel ramp. When you dramatically press the gas pedal, in order to instantly accelerate, it opens very widely, with the ECU, accepting a signal with the DPDZ about the position of the flap, without having the right pressure, is simply not capable of providing the engine with the required amount of fuel.
In cars with automatic transmission, the car twitches when overclocking due to a faulty gearbox or, for example, because of too low level Oils in it. Sometimes "jokes" with a box can occur after the acb is turned off immediately before the trip, such a phenomenon is "not deadly" and as practice shows, it goes by itself, after several accelerations.
Often the reasons are completely banal, for example:, mesh clogged fuel pump And so on. But I think that you like most of us - the first thing they checked it, but if not, then do it.
The car twitches on the go - reasons
As a rule, such jerks occur due to the failure of the ignition system. However, if the trouble occurred on the road, you can try to easily remove the breakdown. For this we do the following:
- Turn off the ignition, lift the hood and make sure that all high-voltage wires are securely fixed on the coil and candles.
- Then get the engine and listen to the engine, listen, are there no extraneous crackles or clicks. The point is to test if there is no "breakdowns for mass", that is, if the spark is still somewhere except the candle. It is best that it is checked in the dark, then you will not only hear the crackle, but also you will see how it beats, for example, on the body or else somewhere.
