Imagine the perfect fuel for fleet operators,
professional drivers and other high mileage users.
A vehicle fuel that can lower your maintenance costs
by actually reducing engine wear. A fuel that’s
already cheaper than traditional fuels and which has
become even ‘cheaper’ since the Government
exempted it from recent and pending fuel tax increases.
A 99 RON octane fuel that’s high in performance,
but low in emissions, and that is a perfect match for
the wizardry of today’s powerful and sophisticated
engine technology.
What would you imagine – the latest biofuel?
Hydrogen technology? A prototype fuel the Government
wants to support into the market?
Well, how about automotive LPG? It’s been proven
to reduce engine wear and lower vehicle running costs,
it’s cleaner-burning, there is plenty of it and
the latest technology sequential direct injection (SDI)
LPG systems are the equal of anything you’ll find
under the bonnet of a petrol or diesel vehicle.
Add to that Government’s decision to exempt
it from the last two tax hikes, (and the pending increase
of 5.6 cents/litre for petrol and diesel due in April
2005) and LPG becomes a very attractive option for motorists
looking for a high performance, low cost transport fuel
that obviously enjoys Government support.
In short the perfect fuel – which is why so
many taxi drivers use it.
Unfortunately, some drivers still labour under various
misconceptions about LPG. Two key ones are the level
of sophistication and performance LPG offers, and, more
recently – because of all the publicity about
the Maui gasfield run-down – whether there is
enough LPG left.
The issue of LPG supply is simple to deal with –
there are simply no supply problems at all, says Rockgas,
New Zealand’s leading LPG supplier.
“Maui is only one option for us,” said
marketing manager, Michael Hughes.
“We currently source LPG from several gas-fields
within New Zealand and overseas and, in fact, we have
been supplying a mix of domestic and imported product
for some time now.
“We’re currently investing heavily in
new LPG infrastructure in the South Island and we certainly
wouldn’t be doing that if we were concerned about
security of supply.
“As far as we are concerned, it’s business
as usual and continued fuel availability is assured.”
The other misconception surrounding LPG – that
of its performance – is equally simple to dispel.
Today’s LPG systems are as sophisticated, as performance-oriented
and as reliable as anything that dwells beneath the
bonnet of a diesel or petrol vehicle.
“Twenty years ago, when installers were fitting
the early LPG systems into 1.3 litre Ford Lasers for
example, drivers may have had cause for concern,”
Michael says. “But comparing LPG technology then
and now is like comparing a Model T with the latest
Falcon.
“Get behind the wheel of an LPG SDI vehicle
and you would be extremely hard-pressed to tell whether
you were driving on petrol or LPG.
“The only noticeable difference would be the
fuel savings you would enjoy at the end of the month.”
Sequential direct injection – SDI - systems
are the latest technological advance in the automotive
LPG world. According to Mike Gibbons of Pacific Alternative
Fuels, SDI equipment is hi-tech stuff.
“It has been available for some time overseas
for four cylinder 120kW engines, but now they are releasing
conversion systems that are designed specifically for
the six cylinder 200kW engines that we tend to run on
LPG in New Zealand. Most LPG manufacturers are introducing
them now.”
Mike says the LPG SDI systems work on the petrol injection
fuelling cycle. This means the original petrol engine
timing is maintained, emissions are reduced even further
and performance is a mirror-image of what the vehicle
would achieve on petrol.
The new equipment is for dual fuel conversions but some
dedicated systems are being developed.
Michael Hughes says these latest systems just go to
show the potential of LPG.
“It may be misunderstood in some quarters, but
it’s a thoroughly modern fuel – clean and
powerful, and backed with advanced technology.
“The fact that Government exempted it from increases
to fuel tax levies also indicates the fuel has some
support on high for environmental reasons.”
That New Zealand does have a transport pollution problem
is beyond doubt, says Michael. “Emissions are
so bad that a Ministry of Transport report shows around
399 people over the age of 30 die prematurely each year
from vehicle-related pollution.
“LPG can make a real difference in respect of
the occupational safety and health dangers associated
with breathing in engine fumes.
“Whereas diesel engines emit cancer-causing
particulate matter (PM10s and 2.5s) and petrol contains
benzenes and other hazardous additives, LPG is much,
much cleaner.
“That means real health benefits for people
who spend a lot of their time in and around vehicles.
In particular, those taxi drivers who are constantly
exposed to tail-pipe emissions whilst loading and unloading
luggage for passengers”.
So, imagine if you will that perfect fuel. One that
cuts your costs, delivers performance, looks after your
engine, preserves the environment, protects your health,
is readily available, is cheaper and is exempted from
tax increases.
