The first experimentation with variable valve timing and lift was performed by General Motors. GM was actually interested in throttling the intake valves in order to reduce emissions. This was done by minimizing the amount of lift at low load to keep the intake velocity higher, thereby atomizing the intake charge. GM encountered problems running at very low lift, and abandoned the project.

The first functional variable valve timing system, including variable lift, was developed at Fiat. Developed by Giovanni Torazza in the 1970s, the system used hydraulic pressure to vary the fulcrum of the cam followers. The hydraulic pressure changed according to engine speed and intake pressure. The typical opening variation was 37%.

Variable valve timing was the sole domain of overhead cam engines until 2005, when General Motors began offering the LZE and LZ4, pushrod V6 engines with VVT. For the 2006 model year, General Motors will introduce the Vortec 6200, the first mass-produced pushrod engine with variable valve timing.

Thanks for that, anyone who has really played with a dohc vtec motor and didint really know what they where looking at, that probably made alot more sense to them now.

Works better as very tall engine cooling.
