METHODS OF ENVIRONMENTAL PROTECTION AND FUEL ECONOMY
In order to maintain the proper functioning of your vehicle, to reduce the release of
harmful substances into the environment and to achieve the most economical driving
possible, it is important that your vehicle is properly maintained..
Clean or replace the air filter
The air filter is used to filter out debris entering the cylinder. If there is too much dirt
or too much moisture, it blocks the air, which in turn causes the fuel-air mixture to be
too dense, incomplete combustion, the engine to lack power, excessive fuel
consumption and release of harmful substances into the environment. The fuel filter
must therefore be unblocked. A blocked filter should be replaced to avoid improper
operation.
Adjust or replace carburetor
A malfunctioning carburetor causes the fuel and air mixture to be too dense or too
thin, incomplete combustion, excessive fuel consumption and release of harmful
substances into the environment.
