Bi-Phase LPEFI - born in the USA
It comes as no surprise that developing autogas markets initially use imported LPG systems supplied by the industry's renowned manufacturers and only then local companies develop and produce their own solutions. It wasn't like that in countries where autogas as motor fuel "began”, like Italy or the Netherlands – they had to invent it all from scratch – but now that technology's commonly available, it just wouldn't make much sense to reinvent the wheel if you can learn from others and move on forward on your own.
The LPEFI is a liquid state multipoint port injection system, already EPA- and CARB-certified for use on a number of popular modern engines, including:
- GM 8,1 l (MY 2003-2009);
- GM/Isuzu 6,0 l (MY 2008-2014);
- Ford 5,4 l (MY 2010-2014);
- Ford 6,8 l (MY 2012-2014).
As is usual with liquid state injection systems, the LPEFI doesn't require a vapouriser, but features an LPG pump on the fuel tank to maintain appropriate pressure (to avoid vapour locks). Here it's called the LPDM (liquid propane delivery module). The tanks are claimed to be specifically engineered and designed for easy bolt-on installation. According to Bi-Phase, the company holds more than 100 patents protecting each and every part of the system.
