Shots muffler can easily lead to rupture or damage to the cavity (cavities) that will result in tangible costs associated with the purchase and installation of new parts on the car muffler.Moreover, incorrect adjustment of the engine "will help" bring down more expensive parts than the silencer and resonator.On gasoline engines, there are several reasons for the appearance of "fire", which may begin as a result of failure of one of the systems of cars.

power supply system (carburetor)



very loud bang in the muffler shows that the fuel burns in the exhaust system.This can occur due to incorrect carburetor adjustment (screw "quality mix"), which resulted in a fuel mixture becomes too much gasoline.This leads to the fact that the fuel is not completely combusted in the cylinders (at the time of
the compression stroke) and "flies" directly into the muffler, where the ignited at high temperatures.Before the adjustment of the carburettor, make sure the air filter is in good condition.

gas distribution mechanism (RM)



If the shots are heard in the muffler at all engine operating modes (small, medium, large momentum), it makes sense to check the thermal backlashes in valves.The valve seat very tightly closes the entrance (exit) in the cylinders;while reducing the gap to make it impossible - there is a crack.As a result, the fuel mixture is partially seeps into the exhaust manifold, which lights up with a roar.Get rid of popping can be elementary control valves - for each vehicle model provided a gap.When making adjustments do not forget that there is an expansion upon heating the metal, and the gap in a warm engine is smaller than a cold.

Ignition



too late may also trigger the ignition of cotton in the muffler.The reason - the timing adjustments are illiterate.If it is set up correctly, the spark between the electrodes of the spark must occur at a time when the piston overcomes the top dead center (or TDC).Inflammation of the mixture pushes the piston;when the spark ignition lag will occur when he had gone down, the movement is accompanied by the opening of the exhaust valve.The resultant mixture is ignited and "jumps" through the open valve into the exhaust manifold, where it is cotton.
