Starting characteristics,
service life, performance, fuel
consumption, and exhaust
performance – these critical
engine parameters are all
influenced by the spark
plug. The functional part of
the spark plug is concealed
within the engine’s combus-
tion chamber; only a part of
the insulator and connector
are visible from outside.
During operation, spark
plugs have to deliver out-
standing performance: in all
situations they must produce
a spark reliably, ensure cor-
rect cold starts, and prevent
misfiring – even under
extreme conditions – playing
their part in ensuring opti-
mum combustion with low
emissions.
They have to cope with
temperatures in the com-
bustion chamber of up to
3,000 °C and pressures of up
to 100 bar, not to mention
ignition voltages of up to
40,000 volts, with transient
power peaks of up to 300 A.
Chemical influences also
make high demands on
quality. So this is extremely
tough work , that the spark
plug has to maintain for many
thousands of kilometers.
BERU spark plugs are highly
specialized, precision com-
ponents, which have been
developed to meet vehicle
manufacturers’ specifications
and are produced on up to
date production lines.
