METHODS OF ENVIRONMENTAL PROTECTION AND FUEL SAVING
In order to maintain the proper operation of the vehicle, reduce the emission of harmful
substances into the environment and achieve the most economical driving, it is
necessary to properly carry out the maintenance of the vehicle.
Clean or replace the air filter
An air filter is used to filter contaminants entering the cylinder. If there is too much dirt
or there is too much moisture, this causes air access to be blocked, which in turn causes
the fuel-air mixture to be too dense, the combustion incomplete, the engine lacks power,
excessive fuel consumption and the release of harmful substances into the environment.
The fuel filter must therefore be unlocked. The blocked filter should be replaced to avoid
improper operation.
Clean, adjust and replace the spark plug
Remove dirt from the spark plug and adjust the ground clearance. If it functions
incorrectly, it should be replaced. Otherwise, its resistance is high and the spark is small,
so that the fuel does not burn completely. This causes excessive fuel consumption and
the release of harmful substances into the environment.
Adjust or replace valves and set valve clearances
