A 2.0L naturally aspirated with this new tech will increase the peak power of the conventional same engine, but not too much. The increase is expected by the optimization of the compression ratio at and above peak power revs where the aspiration of the engine worsens. On the other hand, a good...

The hybrid cars are way better in CO2 emissions (i.e. in fuel economy) in downtown traffic compared to conventional cars of same weight. In the hybrid car the thermal engine operates only from time to time (at optimum – as regards economy and emissions – conditions, like 3500 rpm and 80%...

When you move the crankshaft up to increase the compression the flywheel is doing nothing. It does not feel the displacement of the secondary crankshaft (light brown). Only the eccentric rings feel the displacement of the secondary crankshaft (blue) and through the conrods the pistons move a...

The basics of V8 patcrank VCR are shown in this simple gif animation: The main crankshaft (red) is conventionally supported on the crankcase and drives conventionally the flywheel and the gearbox. If you do not want to open the "exe" animation for more, you can alternatively open the...

This is the pat-head pattakon VCR. It is similar to SAAB's SVC, yet quite different. For more about pat-head VCR : http://www.pattakon.com/pattakonVCR.htm Thanks Manousos

Take a look at http://www.pattakon.com . The patcrank VCR in a V-8: All it takes is four slim and lightweight secondary connecting rods and one thin and lightweight crankshaft, i.e. 5 lightweight, and cheap to make, moving pieces in total, plus one slow moving control frame. A...
