Reap the full potential!
Petrol prices are constantly on the rise!
Ten years ago, one litre of premium petrol cost 1.05 €. At Easter in 2012, the price rose to a temporary all-time
high of 1.70 €. That‘s a price increase of 60 percent in one decade – and everyone knows that there‘s no end
in sight to the spiralling prices. The development is causing an increasing number of drivers to convert their
vehicles to liquefied petroleum gas (LPG). Today, 500,000 vehicles are on the road with an additional liquid
gas tank in Germany alone. By 2014, this figure is expected to increase to around 900,000 vehicles.
> LPG VEHICLES
500,000: This was the number of liquefied petroleum gas vehicles in Germany in 2012 – and the trend was rising.
Back in 2004, there were only 50,000.
Dramatic: Fuel prices are climbing to dizzying heights. It‘s no wonder that an increasing number of
drivers are discovering liquefied petroleum gas as an alternative – especially as there has also been
a noticeable improvement in the network of service stations.

Why LPG LaserLine?
Anyone investing a lot of money in converting their vehicle wants the gas system to run as efficiently
and for as long as possible. There is a clear willingness to invest in more expensive spark plugs. With
LPG LaserLine, NGK is offering you precisely the right product at precisely the right time.
>
In gas operation, the required ignition voltage increases by up to 5,000 volt – increasing the risk of
ignition coil failure. LPG LaserLine spark plugs, on the other hand, work with low ignition voltage and
unburden the ignition coils.
LPG LASERLINE SPARK PLUGS FROM NGK
>
The temperature load of the spark plug increases considerably with the combustion of LPG. The spark
plug must be able to dissipate more heat. LPG LaserLine spark plugs are also ideally prepared for this.
> Eight double precious metal spark plugs for
natural gas and liquefied gas-operated engines

Conventional electrode and housing materials corrode very quickly with the combustion of LPG. LPG
LaserLine spark plugs have precious metal electrodes which are almost entirely wear-resistant and also

Lambda sensors –
the basis for clean operation
Since the 1980s, regulated catalytic converters have been used
in cars with petrol engines in order to convert pollutants into
environmentally-friendly gasses as effectively as possible. To do
this, the engine requires at least one Lambda sensor in front of
the catalytic converter –
a regulating sensor. Modern vehicles also have a diagnostic
sensor behind the catalytic converter. The regulating sensor
supports the engine control with the stoichiometric mixture.
Because with this mixture (14.7 kg air to 1 kg fuel), the engine
works efficiently and the 3-way catalytic converter can convert
the created nitrogen oxide (NOX), hydrocarbon (HC) and
carbon monoxide (CO) almost entirely. The diagnostic sensor
