Helpful Hints: Periodically check the exhaust system. If there is an increased noise level from the exhaust system, check its tightness. To do this, start the engine and inspect the entire system. By running your hand over the places of a possible leak, without touching the nodes, you will immediately feel the leakage of gases. If necessary, replace rusted and burnt parts.
Warnings! Allow the exhaust system to cool before repairing the exhaust system, as the exhaust system becomes very hot when the engine is running. Exhaust gases are poisonous, their poisoning occurs imperceptibly, so be sure to open the gate before starting the engine in the garage!
On vehicles with multiport fuel injection with feedback, a catalytic converter is installed between the exhaust pipe of the muffler and the resonator. The use of a neutralizer significantly reduces emissions of hydrocarbons, carbon oxides and nitrogen into the atmosphere. When the exhaust gases pass through the converter, most of the hydrocarbons are converted into water vapor, carbon monoxide into carbon dioxide (carbon dioxide), nitrogen oxides - into nitrogen. For the efficient operation of the converter, a very precise ratio of air and fuel supplied to the engine cylinders is necessary, therefore, converters are installed only on cars equipped with a fuel injection system.
The catalytic converter consists of two ceramic blocks with catalysts in microchannels. The blocks are installed in a non-separable metal case.
Arrangement of elements of system of release of the fulfilled gases on the car with system of the distributed injection of fuel without feedback: 1 – a pillow of a suspension bracket of system of release of the fulfilled gases; 2 - silencer; 3 - resonator; 4 - downpipe
