New technology is claiming to deliver fuel efficiencies of between 10–20pc, by switching to a combination of diesel and liquid propane gas (LPG) – when there is an increase in diesel prices.
The system – being introduced to Australian industry by FuelSave Australia Pty Ltd – enables users to cut engine wear also, and reduce environmental emissions from mobile and stationary diesel engines, ranging from tractors (see picture), trucks, ‘dozers and harvesters through to standby plants such as generators, compressors and fixed diesel installations.
“The great thing about this system is that it is not some pie-in-the-sky theory but a down-to-earth technology, already used in European heavy vehicle fleet operations, and in service in Australia,” according to CEO, FuelSave Australia (FSA), David Redfern.
He says the technology works by introducing a small amount of LPG into the engine via its air intake system.
The gas acts to improve the combustion process, ensuring almost all the diesel injected, is burnt.
“Most diesel engines have a burn rate of 75-80pc with the rest of the diesel being burned in the exhaust system, or blown out as black smoke.
"With the FSA system, the burn rate goes up to 95-98pc,” Mr Redfern said.
The FSA system is the big vehicle brother of the system, widely applied by Diesel/Gas Australia to 4WDs and other smaller working vehicles.
“Mechanical LPG systems have been in use for decades,” Mr Redfern said.
“Our technology has been in development since the late 1990s and has been constantly refined with modern electronic controls, very similar in simple principle to injection control units used in cars.”
Mr Redfern says the injection of a small quantity of LPG vapour into the diesel combustion process, creates a simultaneous burn.
Modern electronics allow the controls to accurately meter and inject precise, small amounts of gas.
New vehicle warranties are not affected by after-market LPG conversions, according to FSA which says the system can also be rented over three, four or five years, according to vehicle type.
The LPG fuel management system is housed in a “black box” that determines the required amount of gas, optimum pressure and injection timing required by the engine.
The system’s “bolt on” technology is transferable from one vehicle to another.
All kits are fitted to Australian Standards AS1425.
