 The
firm ENKER operates in holding system of the company ENERGOINVEST Sarajevo.
It was founded in 1973 and a regular production has been starting in 1974.
ENERGOINVEST has before produced spark plugs for petrol engines at the other
locality on the base of an older technology. That production was organized
from 1957 to 1974 what means that ENERGOINVEST has been producing spark
plugs for over 40 years and there is long years experience. During the first
10 years ENKER was making spark plugs under license of the English company
Smith Industries Limited. Since this license was expired ENKER has developed
its own design following successfully development trend at the other world
spark plug
producers. Installed factory capacity is 16 millions of pieces per year.
ENKER produces more than 100 spark plug with different thread sizes: M 10,
M12, M14, M18, with flat and conical seats and thread lengths according to
ISO standard for spark plugs. They are adopted by their design to engines of
automobiles, motorcycles, trucks and buses, agricultural machines, tractors,
marine inboard and outboard, chain saws. Also ENKER produces special spark
plugs for aircrafts and armored military vehicles. We are producing spark
plugs
under two trade names, ENKER, i.e. BOSNIA SUPER. Besides standard spark
plugs, which are recognizable with central electrode of nickel-chrome alloy,
ENKER developed by itself and has been producing successfully spark plugs of
the higher technological level, such as: - Spark plugs with cooper central
electrode - Spark plugs with radio interference suppression - Spark plugs
with several side electrodes (two, three and four) - Spark plugs with
platinum central electrode ENKER exports its products at all five continents
throughout the world.
ENKER SPARK PLUGS
1 - RESISTIVE SPARK PLUGS
2 - THERMOPLASTIC SPARK PLUGS
3 - SPARK PLUGS WITH 2 OR MORE SIDE ELECTRODES
4 - SPARK PLUGS WITH PLATINUM
1 -RESISTIVE SPARK PLUGS
The ever increasing use of modern radio - diffusive and TV
receivers and electronic parts in automobiles
(this particularly applies to automobiles having electronically controlled
fuel injection) have brought requirements for suppression of electromagnetic
radiation of all potential sources causing interferences are created in the
secondary circuit of the ignition system, i.e. its sparking spots ( spark
plugs, ignition distributor contact and platinum points ) Technical
regulations of developed countries impose very high radio interference
protection level. Suppression of this interference source (on spark plugs)
has been mainly done by cables and fittings with resistance installed. The
basic disadvantage of such suppression method is that suppression elements
are far from the interference source. This facilitates far more efficient
suppression of interferences (elimination of noise, sputtering, ets.).
Besides, the fitted resistor lowers the electrode erosion and therefore
extends the spark plug life. Resistive spark plugs ENKER have suffix "R"
following the numerical type designation
2 - S. PLUGS WITH COPPER-CORED ELECTRODES-THERMOPLASTIC
Spark
plugs of high technological level, having electrodes with copper - core and
nickel-chrome alloy envelope. This provides better heat conductivity, i.e.
faster achievement of the self-cleaning temperature and elimination of
carbon (soot) deposits. Also, at higher temperatures, heat dissipation is
much less frequent. Thermoplastic ENKER Spark Plug with copper - cored
central electrode works at lower temperatures than a standard one. This
means it is colder, what is in direct relation with lower erosion.
Thermoplastic spark plugs ENKER make the heat range wider, provide better
cold start, acceleration without load, optimum fuel consumption (more fuel
is burned due to stronger spark), more efficient under extremely heavy
conditions and significantly longer life time. Thermoplastic ENKER spark
plugs have suffix "C" following the numerical type designation.
3 - SPARK PLUGS WITH MORE ELECTRODES
Development of automobile industry has recently
improved to a high extent so that requirements
for servicing of automobile assemblies and parts have been brought down to
minimum. In order to increase spark plug life we have introduced spark plugs
with several electrodes. Surfaces of side and central electrodes are
considerably increased and therefore the erosion degree is decreased. This
makes spark plug gap more stable in an extended period and therefore the
voltage required for the mixture ignition is almost constant. This also
provides more reliable engine start (particularly in cold weather), lower
fuel consumption and considerably longer spark plug life time.
ENKER spark plugs with 2 electrodes have suffix "U" following the numerical
type designation.
ENKER spark plugs with 3 electrodes have suffix "D" following the numerical
type designation.
ENKER spark plugs with 4 electrodes have suffix "Q" following the numerical
type designation.
4 - SPARK PLUGS WITH PLATINUM TIPPED ELECTRODES
Central electrode of these spark plugs is made of a highly wear resistant
platinum alloy by a special process. Besides, this platinum alloy is very
good heat and electricity conductor. Central electrode wear rate, caused by
corrosion due to combustion and erosion due to sparking, has been
considerably reduced. In this way, ignition conditions between spark plug
replacement intervals remain approximately the same i.e. optimum electrode
gap and ignition voltage required remain almost constant. Characteristics of
the power secondary circuit are improved and the existing voltage reserve is
maintained. That is why the electrodes may be relatively thin end
consequently a spark can easily pass through the mixture. By extending the
insulator nose and fitting the platinum tipped electrode, the insulator nose
can easily be heated up, i.e. self-cleaning temperature is easily achieved
(to eliminate combustion deposits) at a lower r.p.m. and heat dissipation is
increased under high engine loads. Platinum spark plugs provide an easier
engine start even with lower accumulator power, which offers optimum fuel
consumption and more efficient engine run under all operating conditions.
