Where it comes from
LPG (Liquefied Petroleum Gas) is obtained during the
refining process of crude oil, and unlike some other
fuels, there is currently a surplus of approx. 4 million
tonnes of LPG per year from the North Sea alone, and this
is estimated to increase.
Once this gas
is pressurised, it becomes liquid, and is pumped into
your vehicle in its liquid form. LPG has a higher octane
level than four star or unleaded, and does not contain
any lead, or other additives. Once released into your
engine, it will naturally become a pure gas, resulting in
a cleaner more efficient combustion.
Engine emissions of carbon monoxide are almost reduced to
zero, and the lack of harmful acids and carbon deposits
prolongs the life of your engine, and also reduces
servicing costs. You can also expect a longer life from
your engine oil, as this is not being diluted.
is almost exactly the same as with petrol, and there is
no difference in the driving style of your vehicle. Even
cold starting is exactly the same as petrol.
LPG is become
popular in the UK, having been used for many years
throughout Europe. You will notice an increasing number
of LPG pumps at your local filling stations.
We fit only the very
latest SGI & VSI type of Systems
Sequential Gas Injection (SGI)
This type of LPG
conversion gives almost identical characteristics to
the vehicles original petrol-injection systems. This new
system, Sequential Gas Injection (SGI), has been
developed at the request of and in close collaboration
with several automobile manufacturers.
their needs it has been important to retain the original
characteristics of the car. So, after the SGI system has
been installed, reliability and quality remain virtually
unchanged. The key to the SGI system is a new gas
injector, which behaves comparably to a modern petrol
of the SGI System
Performance and driving characteristics almost identical
Quality and reliability conform to automobile-industry
Fast application development for the retrofit market
SGI concept meets new emission requirements and complies
Wide variety of applications for the latest, heavily-loaded
and sophisticated executive vehicles.
the SGI System Works
Gas flows from the LPG tank to a vaporise / pressure
regulator in the engine compartment. The liquid gas is
vaporized in this regulator and the LPG pressure is
adjusted to a suitable value. The LPG then flows through
the common rail to the various SGI injectors (the number
of which depends on the number of cylinders) which are
attached to the inlet manifold. The SGI computer
calculates the ignition moment and the duration of
injection for each cylinder independently, resulting in
maximum drivability and minimum exhaust emission.
Sequential System (VSI)
VSI is an abbreviation for "Vapour Sequential Injection", the latest
development from Prins Autogassystemen B.V.
this development a new phase has commenced for the LPG and CNG industry
The system is fully integrated "master - slave" with the petrol
management system which makes the system EOBD compatible so signal
emulation is not required.
By injecting the LPG the same way as on petrol there is no difference
anymore driving on petrol or driving on LPG. You will only notice the
difference at the pump and benefit the environment.
In close cooperation with Keihin corp. in Japan Prins Autogassystemen
B.V. developed their LPG/CNG injector. Keihin Corp. one of the worlds
leading injector manufacturer, ensuring OEM quality and reliability. The
injector is perfect linear from 2,5 ms with a performance guaranteed and
a long durability 290 million cycles (OEM quality). These specifications
discern our injector from other injectors in market.
The ECM injector driver capability up to 8 cylinders. In combination
with our special software strategy we can achieve the best drive-ability
with excellent emissions.
Other changes in comparison with the first generation gas injection
1. Small and compact design suits all cabin interiors, via smart touch
2. An extra dry gas filter
3. Compact design reducer for ease of installation
