SomptinGuy,
Who were you working for at Lucas, was it BGB? If you get a copy of SAE Paper 880602, you will find that at the time you were working in west London there were other people at the same site, working on an integrated camless valvetrain and common rail fuel injection system. Very advanced for it's time, but simplified versions of this will appear in the future, I am convinced.
