  1. They all used Bosch engine management so no surprise they were all up to the same fakery.

  2. Konisegg Freevalve solves the IC engine cost, emissions and consumption issues. But VW and others ignore it because they can’t claim it’s their idea. The same things happened with Orbital direct injection - we can’t see it - not invented here.

  3. Lean mixtures don’t send enough HCs down to the cat. Catalysts overheat when the exhaust gas is too rich. Burning off the unburnt fuel overheats the cat. Cooling the exhaust gas allows the turbo to work harder at lower power settings without getting over cooked at full throttle.
