Old thread I know, but a couple of thoughts. Take an engine with individual intake runners, say an air cooled VW with dual port heads, build a fuel injection system with individual throttle plates in the runners, and the air intake through a common Mass Airflow Sensor near the air cleaner. Have a lever system built into the valve covers, which when operated holds both valves in two cylinders open a little bit, the pistons will need to have the valve pockets recessed enough so they didn't hit the valves. When activated, the "4 to 2" switch would turn off the fuel, and hold the valves open. The main pumping loss in a "dead" cylinder is the pulling a vacuum against a close butterfly plate and compressing the air in a cylinder by 9 or 10 times. Try turning an air compressor by hand, and then do it with the reed valve held open.
Thoughts anyone?
