Must I diminish the recess of the electrodes in cars converted for CNG?
The
converted vehicles the CNG require greater tension of the ignition
system for the formation of the spark in the spark plug, this occur
in function of the characteristics of fuel CNG, therefore is very
important the use of products of high quality. Using the NGK's ignition
cable and spark plugs it is not necessary to diminish the recess
enters the spark plug electrodes because they have a high capacity
of insulation.
Case the installed kit will not be suitable to the vehicle or without
all the components (complete) can occur Back Fire and in these cases
as palliative measure it can be diminished in the distance between
the electrodes.
Obs.: For spark plugs with opening above of 1.0 mm, to diminish
the recess for 1.0. For example: TR6B-13 spark plug, opening of
1.3 mm to diminish for 1.0 mm
