An exhaust pipe can be a good tool for diagnosing the power infrastructure of a car with all adjacent nodes. Perhaps, any motorist sooner or later encountered characteristic pops through the muffler. This is a clear indication of a malfunction that must be sought and fixed. Why is he shooting at the silencer? There are many reasons, they are different and each of them requires special attention.
Delayed ignition
Ignition settings with incorrect configuration may well lead to such problems. The system should be checked from the ignition timing - if it is late, then shots through the silencer cannot be avoided. The spark is delayed, causing some fuel to be sent to the manifold. As a result, you can get not only noise effects, but also combustion of valves.
But why shoots the silencerif the ignition settings are set correctly? In this case, the problem should be sought in electrical engineering. Either the spark itself has a weak charge and the ignition of the combustible mass simply does not work, or there are malfunctions in the contacts with the connection of the toggle switch. Problems are eliminated by a complete revision of the ignition system with a possible replacement of the contact group. At the same time, it does not hurt to check the spark plug - whether it corresponds to the glow number of the engine and whether it is in working order in principle.
Violations in the system of gas distribution phases
The same violations of the settings in the timing system entail premature opening of the exhaust valves with similar consequences. Part of the fuel under strong pressure enters the manifold, where unburned gases provoke a shot. You should immediately check the electronic timing control system (if any). But even in this case, the settings can be set correctly. Then why is the engine firing at the muffler?
Most likely the problem is due to a technical problem. As a rule, there are malfunctions in the timing belt, which can either slip or stretch more than usual. On its back surface there are special teeth that cling to the gears, ensuring the optimal intensity of the movement of the phases. Otherwise, the system also violates the mode of operation of the engine, which leads to pops. This is an extremely unpleasant situation, and it is necessary to act as quickly as possible, since a breakdown in the shortest possible time leads to the destruction of valves with a piston group.
Violationsthermal gap regulation
Overloading the engine during abrupt transitions between different speed levels also causes strong exhaust emissions. If this occurs at low and high speeds, then we can talk about a failure of the thermal gap between the cylinder block and the valve. Repair is carried out by reinstalling the camshaft pusher. It should be in a position where the gap will be minimal.
Problems in injection engine
Most often, owners of carburetor engines complain about muffler pops, but injection machines are also not spared from such nuances of operation. Moreover, the reasons are the same as in the case of the carburetor. This may be a malfunction of the spark plug, and incorrect timing adjustment, and the same thermal clearance. But why is it shooting at the muffler of an injection car if all the above problems are not detected?
The electronics in the control unit may fail. The regulation of the combustible mixture directly depends on it, and the slightest violation can lead not only to shots in the silencer, but also to mechanical breakdowns. Even if during the maintenance it was possible to eliminate the malfunction in the control unit, it would be useful to carry out a comprehensive diagnosis of the power filling in order to detect possible hidden problems.
Why is the VAZ firing at the muffler?
Domestic AvtoVAZ cars often suffer from such shortcomings. If there is a serious idle run, shots in the silencer may indicate problems incarburetor. The way out will be the regulation of the shaft play, the replacement of the toggle switch or the vacuum corrector already in the ignition system. But why does it shoot at the muffler when releasing gas in VAZ models?
The reason may well be a malfunction of the exhaust system itself. For example, low-quality atomizers oversaturate the cylinder or there is a lack of air in the fuel mixture. In both cases, replacement of functional elements - atomizer and filters is required. If possible, it is worth trying the regulation of the supply of a combustible mixture, but if such phenomena are observed in normal mode, then the problem is obviously technical.
Why does the motorcycle fire at the muffler?
Motorcycle pops due to misregulation of the fuel mixture. At the first stage, you should check the carburetor, after which, in accordance with the instructions, lean the fuel mixture. A rich mixture often causes fuel to burn out in pipes.
But, for example, why "Ural" shoots at the muffler, if the standard gasoline is also used? If everything is in order with the carburetor and the fuel is regulated in the optimal mode, then there can be two reasons for popping: there are malfunctions in the ignition system or the group of cylinders is damaged.
Conclusion
The sensitive mechanism of fuel combustion can cause a lot of trouble if it is not detected in a timely manner. The problem is aggravated by the fact that the mostdifferent and, at first glance, even insignificant reasons - for example, the slightest violation in the contacts of the candle, incorrect settings in the carburetor electronic system, or fuel with unsuitable characteristics. But if, after a comprehensive check of the units and assemblies associated with the supply of a combustible mixture, it turned out that everything was functioning normally, then why is it shooting at the silencer? According to experts, contamination with deposits in cylinders, pipes and combustion chambers may well affect.
The critical accumulation of sediment leads to the occurrence of glow ignition, in which the mixture is able to ignite arbitrarily - enough smoldering soot particles to activate. At the same time, excessive deposits on the valves and in the area of \u200b\u200bclosure of the valve with the seat can prevent it from closing tightly. As a result, fuel enters the outlet through the gap between the seat and the valve, which causes popping.
In other words, only comprehensive care of the power group with the engine and adjacent systems will help prevent such problems with the muffler. Moreover, the firing of the silencer is only a signal that there is a problem. Its consequences can be much more critical than sound discomfort. The main danger can be expressed in the destruction of the piston system.
