Hey,
I found this interesting article.
Mixing a dose of LPG with diesel to improve power and economy

However, the magic comes in the addition of LPG to the diesel fuelling mix. The LPG is added in vapour form prior to the turbo (in turbo engines) or prior to the inlet manifold (in naturally aspirated engines). The LPG, comprising about 25 per cent of the diesel flow, burns along with the diesel in the cylinders. The combination of the diesel/LPG fuel gives the greater power output and lower emissions. The reduced running costs come from an improvement that is realised in diesel fuel economy – and the fact that LPG is a cheaper fuel than diesel.

It seems like promising thing if you have diesel engine. Unfortunately I dont have. Maybe some garage-inventors can make their home-brewed version?
