Fuel grades for engines with spark ignition of a working mix

Standard high-quality grades of fuel are suitable. Quality of fuel considerably influences capacity, kind of work and engine service life. Great value additives (additive) added to fuel thus have. Therefore fill only qualitative grades of fuel with additives.

Fuel use with insufficient value of octane number can lead to the knock, the ignition caused by early installation.
Fuel with higher octane number can be applied in any cases.

At cars in which fuel tank it is necessary to fill unleaded gasoline, it is impossible to insert into a bulk mouth of a fuel tank the gun of a toplivorazdatochny column with etilirovanny gasoline.

At all engines with spark ignition of a working mix (except 16 LZ 2) it is carried out, depending on a grade (octane number) of the filled fuel, automatic control of ignition.
The economic mode of operation of the car is reached by fuel use with the octane number equal 95.

At cars with the engine 16 LZ 2 the electronic system between two values of octane number a way of reinstallation of a coding fork in podkapotny space allows to choose.


The chosen octane number is put before a fixing bracket. If it is necessary to fill gasoline with other octane number, it is necessary to spend a fuel stock in a tank whenever possible to a limit, to refuel, switch off ignition, to take coding fork from the holder, to open fixing bracket, to pull out coding fork, to turn it on 180 °, to insert into place, to fix, establish in the holder.

The fuel grades, having bigger value of octane number, than is coded, do not put any harm.
