The DFV design used a similar cylinder head to the one Duckworth had prototyped on the four-cylinder FVA units on a custom Cosworth cylinder block and crankcase, forming a single 90 ° V8 engine, thus creating a legend in its own right, the DFV-literally meaning " Double Four Valve ".

The formula used was a four-cylinder pushrod ( Over Head Valve ) design that came to be known as the " pre-crossflow " version as both inlet and exhaust ports were located on the same side of the head.

The VTEC engine used Variable Valve Timing to provide increased power in the high rev range, while still allowing low fuel consumption and better idling at low RPMs.

Most 1980s 4-cylinder Fords used the Ford CVH engine, CVH meaning " Compound Valve, Hemispherical ( Head )".

Valve oscilloscopes share this very high input impedance and thus can be used to measure voltages even in very high impedance circuits.

Later mod making tools include The Elder Scrolls Construction Set which shipped with Morrowind, the Aurora toolset which was included with Neverwinter Nights, FRED and FRED2, the mission editors for Freespace and Freespace 2 respectively, the Obsidian tool set for Neverwinter Nights 2, the Garden of Eden Creation Kit SDK for Fallout 3 and the Valve Hammer Editor which is used to create maps for Half-Life, Half-Life 2 and various other games based on the Source engine ( older versions also supported the Quake engine ).

For example the " Regina Valve " is a valve very much similar to the Presta and mostly being used in Italy.

* Pressure Control Valve, used to reduce the amount of pressure in a tank or system of pipes.

In addition, Pitchford commented that Valve and Gearbox had agreed not to " severely modify " the game engine used by Half-Life and Opposing Force as it " risks breaking all of the wonderful work " that the game's custom content community was creating.
