Gas injection

Asked by Dave Webster

I HAVE a 1994 80-Series Landcruiser 4.2-litre non-turbo diesel and I have been told that you can get gas injection fitted that lifts power by about 20 per cent with a 20 per cent fuel saving. As I was thinking of getting the engine turbocharged and heard about this I am now wondering if there is much difference between the two. My vehicle has done about 140,000km.

I DON'T have any direct experience of the system, but South Australian company LPG Autogas Systems has released a dual-fuel system for diesel four-wheel-drives. It substitutes about 20 per cent of LPG, which enters in the intake manifold. It claims that it improves combustion and as a result lifts economy and boosts engine output by about 20 per cent on a naturally aspirated engine.
