It appears Orbital will be furnishing OEM and Retro-fit(after-market) kits.

Orbital aims to freshen LPG's image
Gas gains: Manufacturers such as Ford will swing to sequential liquid LPG
injection, according to supplier Orbital.
Next-gen liquid-injection 'will improve performance, cost of going with LPG'

By IAN PORTER 19 June 2009


AUSTRALIA'S Orbital Corporation has set out to transform the image of LPG in the
minds of car drivers in a bid to broaden the fuel's market penetration from the
current five per cent.

Orbital recently became a leading player in the field when it acquired the LPG
operations of Boral group, because directors could see the potential for gas to
replace petrol and diesel as oil becomes scarcer in coming years.

Included in the Boral business is a contract for the supply of the hardware that
for Ford's big-selling E-Gas Falcon, which comprises about 20 per cent of Falcon
volumes and is popular with fleet operators.

Orbital Gas Products managing director Tony Fitzgerald told a Society of
Automotive Engineers (SAE) seminar on gaseous fuels in Melbourne this week that
the next generation of liquid LPG systems would offer a significant advance.

He said Orbital would adopt sequential liquid injection and sequential vapour
systems in place of the traditional fumigator system, which releases gas in the
inlet port. The aim is to make using gas as easy as using petrol, with no
noticeable change in driving characteristics.

"Sequential systems (which release fuel only when the inlet port is open) will
appear in many forms, from the car-makers as original equipment in dedicated or
bi-fuel form, for after-OE installation in bi-fuel systems and as retro-fit for
Euro III and Euro IV compliance.

"There is a wide range of quality in the LPG market at the moment, and it is
important Orbital introduces very high quality products."

Mr Fitzgerald said he believed the emphasis would swing away from retro-fit
market to a situation where most LPG vehicles would be built by the car-makers.

The manufacturers would be able to optimise fuel settings and emissions
calibrations, although Mr Fitzgerald said Orbital would strive to achieve
standardisation of its own after-market kits.

"We will conduct an extensive calibration program so that there will be no need
for installers to make final adjustments. That will also assist in achieving our
aim of matching the driveability of a car on unleaded petrol."

Mr Fitzgerald said Orbital had chosen established partners - Vialle and
Continental - to supply proven components for its Australian systems.

"We will not be trying to invest something new," he said.

"We will be looking to leverage the knowledge of our partners. If then product
is to be reliable, we need to take a conservative approach."

for the us this would be a stellar deal, currently the us has more natural gas than it can use, much of it trapped in off shore hydrates, if vehicles can be run efficiently and reliably we can cut our foreign oil altogether
 
Uh, hang on sports fans. LPG is a byproduct of raw crude refining and natural gas. In the US, LPG is a minor ratio product, well down below 1% of the total hydrocarbon production. LPG available for consumer use makes up about 15% of production, the remaining going to feedstock for the chemical industry, and of that amount, only about 17% destined for transportation use including forklifts.

LPG will never replace diesel or gasoline (dont overlook that I am a major advocate of using LPG as a motorfuel!) but as a third motorfuel, there is a strong case for using LPG and natural gas. Due to the heavy density of gasoline and diesel vehicles currently in use, there could not be enough LPG in production to feed more than about 5% of the US market. Add another 3 to 5% for NG, depending upon whom you talk to.

In the US, Ford is currently offering liquid injection in their F-series pickup truck as provided by Roush.

In Aus we have a lot of gas wells but not a lot of oil, so we import almost all our oil but we export a lot of gas. I don't know the actual numbers. LPG is about 40% of the cost of petrol, probably because of the availability and because of it's lower energy content.

Pat - That's LNG, the liquid version of CNG, not the same as LPG.
 
Your right, LNG is mainly methane and ethane and LPG is mainly propane and butane.

should be able to run both, if it is setup properly so that the ecu can inject more or less fluid and alter the engine timing to match performance
 
Nope, different fuels, different pressures, different temperature saturation levels.

LPG in vapor form MIGHT be able to use CNG vapor, but LPG liquid can NEVER use LNG liquid.
