Rapid technological developments are transforming the LPG Autogas scene in Australia, allowing new Autogas-powered models to challenge their petrol-powered equivalents for performance and fuel economy.
Over recent years several new Autogas systems have been developed which combine advanced electronic management with various fuel injection technologies. The developments have progressed quickly from single point
throttle body injection through to multipoint port injection – both in timed simultaneous injection and timed sequential injection forms. These systems are generally referred to as third and fourth generation.
The most advanced of these – the multipoint timed sequential systems, fourth generation - are functionally very similar to commonly used petrol injection systems. Advantages include quicker engine response, improved fuel efficiency, lower emissions and the elimination of damaging backfire.
Importantly for manufacturers seeking to offer such systems as original equipment the new technology allows compatibility with the electronic control unit (ECU) of the base petrol model, meaning no interference with diagnostic or other functions.
