I have come across a steam injection system some 8 years ago, put into a 9-litre diesel engined London bus and was pushing out some good speed, so it was claimed. the same system was also put into a large lorry but fuel enomony is far shiodrt of conclusion. I believe I styil have the hard copy somewhere, if anyone is interested, I will scan it and put it up here. The company that marketed this invention is no longer trading.

The product was basically a heat exchanger ( a block of metal with internal channels) bolted to the exhaust manifold. It is connected to a large water tank, trickling a small amount of water into the block and turn in to steam. The steam is then channelled into the intake of the engine. The idea and physic is sound, it does work.

How much energy can be recovered or mpa improvement is still yet to be exploited. Unfornately the company did not servive long enough to make this product to the market place, either through a lack of fund or government red tapes (grant assisted product for the buses and lorries).
