1. Periodically inspect the exhaust system for leaks, corrosion and damage, as well as for the reliability of its fastening. Small holes are most easily spotted by briefly plugging the exhaust pipe with a rag while the engine is running.
2. There are special pastes and bandages available for sealing holes and cracks in the exhaust system. They may solve the problem in the short term, but in the long term it is better to replace the damaged section.
3. Inspect the system's mounting rubber bands for damage and replace them if necessary.
4. Removal and installation of the exhaust system is carried out in the same way as for models with a petrol engine.
Emission Control System - General Information
1. Some engines are equipped with an emission control system that reduces the release of pollutants into the atmosphere.
2. Depending on the model, one of the following systems may be installed.

Crankcase emission control system
3. Crankcase ventilation system is installed on all models.
4. Oil vapors and gases that have broken through the piston rings are taken from the crankcase and from under the valve cover through the oil filler tube (which includes an oil separator) and enter the air intake duct, from where they are sucked into the engine along with the air, where they burn).
Exhaust emission control system
5. In order to minimize the content of pollutants in the exhaust gases, some models are equipped with a catalytic converter in the exhaust system.
6. The catalytic converter consists of a chamber containing a fine mesh impregnated with a catalyst. As exhaust gases pass through the converter, the catalyst accelerates the oxidation of carbon monoxide, unburned hydrocarbons and soot, resulting in a significant reduction in the amount of pollutants released into the atmosphere.
